Definitions
- the invention relates to the field of fluid storage, in particular a fluid forming a fuel contained in a tank of a transport device such as a motor vehicle, an aircraft, a boat, or any other mobile equipment.
- the invention is of particular interest, in no way limiting, in the sector of vehicles using hydrogen or other fuels including, for example, biogas.
- the hydrogen, gas or liquefied gas tanks known in the prior art are generally formed of a body comprising a cylindrical jacket on which pre-impregnated technical fibers, for example made of carbon, are deposited by winding. filamentary, so as to form a shell capable of withstanding the pressure of such a fluid which typically ranges from 2 to 70 MPa in use, with admissible ruptures ranging from 8 to 157.5 MPa in rupture.
- the known reservoirs are bulky, expensive taking into account in particular the time required to carry out the filament winding, and likely to undergo significant deformation under the effect of variations in pressure of the fluid carried.
- the known tanks are poorly suited to current and future motorized vehicles which, on the one hand, for reasons of mass to be transported, have an increasingly restricted space to accommodate such tanks and, on the other hand, on the other hand, pose problems of energy autonomy.
- the invention aims to remedy the aforementioned problems and in particular to respond to the need for additional autonomy of vehicles.
- a particular aim of the invention is to provide a reservoir capable of storing a fluid of the biogas or hydrogen type, or more generally of containing a high pressure fluid.
- Another aim of the invention is to provide a solution making it possible to maximize the useful storage volume with regard to the spaces actually available for this in vehicles such as a motor vehicle, aircraft, boat or other mobile equipment.
- the subject of the invention is a reservoir for a transport device such as a motor vehicle, an aircraft or a boat, comprising a body which delimits a cavity intended to contain a fluid, the body comprising a shell forming a tank shell.
- the shell comprises an assembly of fibers forming one or more layers each having several plies linked together by certain of said fibers, called “binding bias fibers”.
- the shell of the tank includes braiding with interlacing of plies, that is to say braided fibers, some of which bind different plies together, which makes it possible to obtain excellent mechanical properties in terms of tenacity.
- 3D interlock H. Lansiaux, D. Soulat, F. Boussu and A. R. Labanieh, Mechanical characterization of 3D warp interlock fabrics linen with different numbers of layers, 24th French Mechanics Congress, Brest, August 26 to 30, 2019.
- Such a braiding technique makes it possible to deposit, at the same time, on a mandrel made to the interior shape of the tank for example, a certain number of braids while interweaving them together in order to avoid, in use, any delamination or any movement between the different braids and thus bring them to work together.
- This technique also allows the construction of a polymorphic shell, whether it is a shell having a simple or classic geometry of the cylindrical type or a complex heteromorphic geometry.
- a shell made of braided fibers with interlaced plies makes it possible in particular to improve the fatigue resistance of the tank compared to a shell produced by filament winding.
- the invention also makes it possible to produce high pressure tanks, with cylindrical or other geometry, and low pressure tanks such as those, for example, used for transporting liquefied petroleum gas.
- the braided shell of the invention makes it possible to reduce the very large deformations which occur on conventional tanks.
- the shell of the tank of the invention thus forms a texture comprising mainly continuous technical fibers.
- These fibers can be of organic, plant, mineral or metallic origin.
- each of the layers comprises a number NI of plies greater than two, the binding bias fibers passing through a number N2 of plies at least equal to two.
- NI can be equal to five and N2 can be equal to two for at least some of the binding bias fibers.
- the body comprises a jacket defining an internal surface which delimits the cavity and an external surface matching an internal surface of the shell.
- the liner may comprise a material such as plastic capable of making the liner impermeable to the fluid contained in the cavity.
- the shirt may comprise a material of organic, plant, mineral or metallic origin.
- the tank comprises one or more reinforcements which each connect the parts of the body arranged opposite to each other.
- these parts connected together by one or more reinforcements can be flat, convex or even concave walls.
- Such reinforcements make it possible to increase the resistance of the tank to the pressure of the fluid carried in the tank, in particular by increasing the resistance to tensile forces.
- each of the reinforcements may comprise a wall made integrally with the jacket.
- the wall of the reinforcement(s) can form a continuous extension of material with the shirt.
- each of the reinforcements can extend along a connection direction.
- connection direction of each of the reinforcements can be perpendicular or oblique relative to one and/or the other of the parts of the body which are connected to each other by this reinforcement.
- each of the reinforcements forms a circumferentially closed external surface around the connection direction along which it extends.
- the entirety of this external surface delimits the cavity of the tank.
- each of the reinforcements forms an internal surface delimiting a hollow space.
- This hollow space can define an opening passing through the tank in the connection direction.
- a given reinforcement can include a wall which forms a solid of revolution or more generally a solid closed around the direction of connection that it constitutes.
- such a reinforcement may have a generally annular or frustoconical geometry, which may be different on different sections of the reinforcement along the connection direction.
- a tank comprising reinforcements forming such hollow spaces can thus form a cellular structure, the jacket delimiting a volume comprising the storage cavity of fluid crossed by cells formed by the hollow spaces of the reinforcements, in which can in particular be housed members of the tie type.
- each of the reinforcements comprises a tie rod housed in the hollow space formed by said wall of the reinforcement.
- the tie comprises one or more layers made up of fibers, the majority of which extend along the bonding direction.
- the tension of the reinforcement(s) can thus form a fibrous texture, which is preferably manufactured using a technique other than braiding with interlacing of plies.
- a majority of fibers can be arranged longitudinally and grouped together by light braiding.
- the orientations of the respective fibers of the shell and the tie(s) make it possible to respond to loading conditions which are completely different between the body and the reinforcement(s).
- the reinforcement(s) are in fact particularly exposed to tensile forces when the pressure is internal to the tank.
- the structure of the body is exposed to all kinds of stresses, namely tensile, bending, compression or even shearing forces.
- the invention makes it possible to manufacture tanks withstanding high internal functional pressures, compatible with the carriage of different types of fluid, for example natural gas at medium pressure (26 MPa in use and 47 MPa in rupture) or hydrogen at high or very high pressure (from 35 to 70 MPa in use and from 78.75 to 157.5 MPa in rupture), impervious to the fluid carried, particularly when it is a gas presenting molecules of very small sizes such as hydrogen, methane or butane molecules, and presenting resistance to different types of environment (e.g. acid, basic, humidity, salt spray, etc.), static mechanics pressure, vibration, shock, endurance, fatigue, aging, fire, ballistic and more generally mechanical, which increases their safety and reliability in use.
- the invention also relates to a method of manufacturing such a tank, comprising a step of braiding the fibers with interlacing of plies so as to form the shell.
- This braiding is preferably carried out on the shirt used as a mandrel.
- the method comprises, for each of the reinforcement(s), a step of manufacturing the tie rod by braiding the fibers forming this tie rod and a step of inserting the tie rod into the hollow space formed by said wall of the reinforcement.

- FIG. 8 is a schematic perspective view, partially cut away, of a tank according to the invention, comprising reinforcements oriented in three mutually orthogonal directions, forming a network of tri-axial reinforcements.
- Figures 1 and 6 to 8 include a frame of reference defining three mutually orthogonal directions DI, D2 and D3.
- DI is a longitudinal direction
- D2 a first transverse direction
- D3 a second transverse direction.
- FIG. 1 a tank 1 conforming to a first embodiment of the invention.
- the tank 1 is intended to equip a motor vehicle in order to supply it with fuel.
- the reservoir 1 of Figure 1 has a generally ovoid shape extending along a longitudinal axis Al, parallel to Dl, so as to present two longitudinal ends IA and IB.
- the tank 1 has a transverse dimension, in particular along D2, which varies along the axis Al. Starting from the longitudinal end IA, this transverse dimension increases to a median longitudinal coordinate, then decreases up to the longitudinal end IB.
- the maximum transverse dimension of the tank 1 according to D2 which is located in this case at said median longitudinal coordinate, can be approximately 500 mm.
- the tank 1 comprises a body which is in this example provided with a jacket 2, a shell 3 and a reinforcement 4.
- the jacket 2 forms an internal surface and an external surface defining a thickness of this jacket 2, which is in this example substantially constant in the different parts of the tank 1.
- the cavity 5 is intended to contain a fluid fuel, gas or liquid, having a pressure of around 70 MPa.
- the shell 3 also comprises an internal surface and an external surface defining a thickness of this shell 3, which is in this example substantially constant in the different parts of the tank 1.
- Shell 3 forms an envelope of tank 1.
- the internal surface of the shell 3 matches the external surface of the liner 2.
- the jacket 2 and the shell 3 thus constitute a double-walled body and each have respective and complementary properties taking into account their respective material and manufacturing process (see further below).
- the reinforcement 4 is in this example configured to connect two parts of the body to each other which are located opposite each other, these opposite parts forming two transverse ends of the body according to D2.
- the reinforcement 4 makes it possible to improve the mechanical resistance of the tank 1, taking into account in particular the pressures and depressions which it undergoes during its use.
- the reinforcement 4 has a generally elongated shape along a direction D4, called “connection direction”, which is in this example parallel to the direction D2 and which passes through said median longitudinal coordinate of the tank 1.
- the reinforcement 4 comprises an external envelope 6, a tie rod 7 and two diffusers 8 (only one diffuser being visible in this figure).
- the reinforcement 4 and its outer envelope 6 comprise a central part 4A and end parts 4B and 4C respectively connected to said transverse ends of the body in the manner described further below.
- the central part 4A of the envelope 6 of the reinforcement 4 has a generally cylindrical geometry defining an axis of symmetry which corresponds to the direction D4.
- the end parts 4B and 4C have a flared geometry, in this case an increasing dimension from the respective end of the central part 4A to which they are connected towards the corresponding part of the jacket 2 to which they are connected.
- the external envelope 6 of the reinforcement 4 defines, radially inside with respect to the direction D4, a hollow space which passes through the jacket 2 of the body of the tank 1 in the direction D4 so as to open onto the external surface of this jacket 2.
- the envelope 6 thus forms a wall which extends circumferentially around D4, forming an internal surface and an external surface which define a thickness of this wall.
- the internal surface of the envelope 6 delimits said hollow space.
- the external surface of the envelope 6 is a circumferentially closed surface around the direction D4.
- the entirety of this external surface delimits the cavity 5 of the tank 1 so that the cavity 5 extends all around the reinforcement 4.
- the external envelope 6 of the reinforcement 4 thus forms a well which passes through the cavity 5.
- the external envelope 6 of the reinforcement 4 is made integrally with the jacket 2, in this case with parts of the jacket 2 forming said transverse ends of the body, so as to form a continuous extension of material.
- the envelope 6 and the jacket 2 comprise a thermoplastic material, making it possible to ensure a sealing function to the fluid contained in the cavity 5.
- the external envelope 6 of the reinforcement 4 is in this example made from a part previously manufactured by machining, injection, roto-molding or even extrusion-blowing.
- the subassembly comprising in continuity of material the jacket 2 and the external envelope 6 of the reinforcement 4 is called "membrane”.
- the membrane can be obtained by crystallization or crosslinking of thermoplastic material constituted on the one hand by said prefabricated part and on the other hand by wall elements held in relation to each other using a appropriate tooling, or more generally by implementing any shaping process such as roto-molding, blowing, or other molding or casting technique, so as to create an assembly by adhesion of material elements.
- the shell 3 is first braided onto the membrane using a ply interlacing braiding process, the membrane being used as a mandrel during braiding.
- Each of the layers comprises an assembly of fibers which are in this example carbon fibers and which are braided so as to form five plies.
- the fibers are called "axial fibers” when they are arranged in a manner substantially linear and “bias fibers” when they are arranged in such a way as to successively intersect other fibers.
- Figure 3 schematically shows a sectional view of part of a layer Cl of the shell 3, in which the assembled folds P1-P5 define a thickness of the layer Cl in a direction D5.
- Each of the folds P1-P5 comprises a series of axial fibers 21, also called “longis”, which are spaced from each other in a direction D6 perpendicular to the direction D5 and to a direction D7 along which they extend.
- the axial fibers 21 specifically increase the mechanical resistance of the layer Cl in the direction D7, making it possible in particular to reduce the deformations of the shell 3 in this direction.
- the layer Cl of Figure 3 comprises ten bias fibers braided on the axial fibers 21, including two external bias fibers 22 and eight binding bias fibers 23-30.
- One of the external bias fibers 22 is braided around the axial fibers 21 of the PI fold.
- the other external bias fiber 22 is braided around the axial fibers 21 of the ply P5.
- the external bias fibers 22 make it possible to smooth the external surfaces of the Cl layer.
- the binding bias fibers 23-30 are braided so as to connect the plies PI to P5 to each other.
- binding bias fibers 23 and 24 connect the folds PI and P2 to each other
- the binding bias fibers 25 and 26 connect the folds P2 and P3 to each other
- the Binding bias fibers 27 and 28 connect the plies P3 and P4 to each other
- binding bias fibers 29 and 30 connect the plies P4 and P5 to each other.
- the binding bias fibers 23-30 are braided so as to each connect two respective adjacent plies, for example the plies PI and P2, so that two non-adjacent plies of the layer Cl, for example the plies PI and P3 , are not linked together directly, but indirectly via, in this example, the fold P2.
- the binding bias fibers 24, 26, 28 and 30 are braided so as to evolve along parallel curves in directions D5 and D6 and in phase opposition to the binding bias fibers 23, 25, 27 and 29 (see figure 3).
- the different layers of the shell 3 can be braided in a similar manner, preferably by modifying the relative orientation of the axial fibers 21 from one layer to another, so as to provide the shell 3 with improved mechanical resistance according to several directions of space.
- the shell 3 thus forms a fibrous texture which can essentially consist of intertwined continuous fibers.
- the number of layers of the shell 3 and/or the number of plies per layer and/or the number of plies directly connected together by binding bias fibers can be modified depending on the desired mechanical properties.
- other technical fibers can be used to braid the shell 3, for example fibers made of glass, basalt, aramid, linen, hemp or even mixed fibers comprising, for example, polyamide or polyethylene filaments.
- the braiding of the shell 3 can also be carried out using a combination of such technical fibers and thermoplastic filaments.
- Such a braiding process makes it possible to deposit layers of dry material in the form of several folds of fibers intertwined with each other, one by one or two by two or even more depending on the needs. This operation can be reproduced several times, by stacking layers, in the same direction or in different directions in order to ensure a good framework of contextures capable of responding to the pressure forces generated by the fluid on the shell 3 of the tank 1.
- Such a braiding process makes it possible to make the deposited fibers conform to the required shapes without fiber distortion and provides considerably improved properties in terms of tenacity, particularly in comparison with filament winding.
- openings can be made in the shell 3 by spacing of fibers which constitute it using a tool such as a conical point, so as not to cut the fibers and allow the shell 3 to retain its mechanical properties.
- the tie rod? prefabricated is inserted into the hollow space formed by the external envelope 6 of the reinforcement 4 through one of the openings thus made in the shell 3.
- a tool comprising a mold 31, metallic or composite, and an axis 32 is then pre-positioned, by introducing the axis 32 through an opening made in the tie rod 7 and passages made in the mold 31.
- the mold 31 is then moved so as to come to rest on the external surface of the shell 3, by tightening nuts 33 cooperating with the axis 32, resulting in a folding of the ends 9 of the tie rod? against parts 10 of the shell 3 which delimit said openings formed by spacing of fibers.
- the parts 10 of the shell 3 are thus enclosed between the tie rod 7 and the membrane formed by the jacket 2 and the external envelope 6 of the reinforcement 4, ensuring a robust mechanical connection between the reinforcement 4 and the body of the tank 1.
- this assembly is then consolidated by injection of a thermosetting resin via orifices (not shown) made in the tooling, after formation of a vacuum in the space delimited by the mold 31 and the membrane integrating the shirt 2 which provides a counter-mold function.
- the injection is carried out using a process known under the Anglo-Saxon name “Vacuum-Assisted Resin Transfer Molding” (VARTM).
- VARTM Vacuum-Assisted Resin Transfer Molding
- the assembly is then subjected to heat treatment in order to stiffen the resin.
- thermosetting resin can be replaced by a thermoplastic type resin, in particular with low viscosity allowing injection into the fibrous structure of the shell 3, or even by a bio-sourced resin.
- the tie rod? is made by light braiding of carbon fibers mainly arranged in a longitudinal / unidirectional manner.
- the majority of fibers forming the tie? extends substantially in the same direction which corresponds to the connection direction D4 when the tie rod 7 is assembled with the other parts of the tank 1.
- Such an assembly of fibers allows the tie rod 7 and subsequently the reinforcement 4 to oppose tensile forces exerted on the reinforcement 4 under the action of the pressure of the fluid carried into the cavity 5.
- tie rod 7 Of course, other technical fibers or different combinations of fibers can be used to form the tie rod 7, including for example glass fibers.
- Figure 4 shows tooling similar to that of Figure 2 which is specifically adapted to the assembly of a reinforcement 4 with a tank body 1 having parts connected by the reinforcement 4 which are inclined relative to the connection direction D4.
- the preceding description applies by analogy to this embodiment.
- the tooling of Figure 4 is distinguished in particular from that of Figure 2 in that it comprises heads 41 forming molds, centered on the axis 32 in openings of the mold 31.
- the heads 41 are arranged at the ends of the tie rod 7 so as to conform these ends when they are folded against the hull 3.
- the geometry of the folded ends of the tie rod results from the shape of the molds 31 themselves.
- the diffusers 8 are here rigid rings comprising for example a reinforced thermoplastic material each enclosed between a respective one of the end parts of the external envelope 6 of the reinforcement 4 and the shell 3 after folding down the ends 9 of the tie rod 7.
- Such diffusers 8 make it possible to improve the distribution of loads on the shell 3, in particular when the ends 9 of the tie rod 7 are folded down.
- the nuts 51 are also rigid rings which may comprise a reinforced thermoplastic material and which in this example have an ogive shape.
- the nuts 51 are arranged in the end parts of the tie rod 7 so as to be axially retained in the direction D4 by the folded ends 9 of the tie rod 7.
- the tooling and the tie rod 7 are in fact configured so that, when the ends 9 of the tie rod 7 are folded, a radially internal part of these ends 9 comes to bear on the nuts 51 and a radially external part of the ends 9 come to rest on the shell 3 (see figure 5).
- the nuts 51 are configured to work in compression, so as to achieve an anti-stricture function capable of reducing the phenomena of sliding of the ends of the reinforcement 4 relative to the shell 3.
- Such anti-restriction nuts 51 are particularly useful for tanks 1 intended to contain a fluid under high or very high pressure, such as hydrogen.
- the diffusers 8 and the nuts 51 can include materials of the polyurethane, polyamide or even polyethylene type, and be reinforced by glass, carbon or other fibers.
- the reinforcement 4 of the tank 1 is in this case similar to that illustrated in Figure 5, the anti-restriction nuts 51 however not being shown in Figure 1.
- the tank 1 in Figure 1 further comprises a filling nozzle 61 integrated into the structure of the shell 3 at the longitudinal end IA of this tank 1.
- the nozzle 61 is configured to establish fluid communication between the cavity 5 and the exterior of the reservoir 1, with a view to filling it or sampling the fluid it contains. It follows from the preceding description that the invention makes it possible to produce a composite tank 1, in this case having a body formed of an internal jacket 2 impermeable to the transported fluid and a braided shell 3 both monolithic, capable of 'endure very high pressures while considerably improving the aspects of fatigue, aging and explosion safety.
- one or more reinforcements similar to the reinforcement 4 described above make it possible to significantly reduce the deformations of the body and to design a tank 1 of varied shape, conformable to the location reserved for its installation in a vehicle.
- a tank 1 according to the invention makes it possible in particular to withstand pressures of several tens of MPa.

- the height according to D2 of tank 1 can be approximately 100 mm.
- the jacket 2 and the shell 3 of the body define different parts 101-103 which define the shape of the tank 1.
- the parts 101 and 102 have a generally planar shape defining a lower wall 101 and an upper wall 102 of the body which extend parallel , facing each other.
- the parts 103 form side walls connecting the walls 101 and 102 so as to form rounded edges of the tank 1.
- the tank 1 comprises in this example a series of reinforcements 4 as described above and which are each configured to connect the parts 101 and 102 of the body to each other.
- the reinforcements 4 are distributed in the tank 1 being spaced two by two at a substantially constant distance in the direction DI and in the direction D3.
- FIG. 7 shows another example of tank 1 according to the invention which is described below only according to its differences compared to tank 1 of Figure 6, the preceding description applying by analogy.
- Tank 1 in Figure 7 has a dimension in direction D2 relatively greater than the height of the tank in Figure 6.
- the upper part of the body comprises several upper walls 104-108 facing the lower wall 101 as well as two transverse walls 109.
- the upper walls 104, 106 and 108 are parallel to the lower wall 101 while the upper walls 105 and 107 are inclined relative to the walls 104, 106 and 108 so as to create a bulge in the tank 1 at its central longitudinal part. .
- the maximum height of tank 1 that is to say the distance along D2 between the lower wall 101 and the upper wall 106, can be approximately 150 mm.
- transverse walls 109 are parallel to the directions DI and D2 and are spaced apart from each other in the direction D3 so as to define a constant width of the tank 1 .
- the reinforcements 4 comprise on the one hand reinforcements 121 similar to those of the tank in Figure 6, that is to say reinforcements 121 connecting the lower wall 101 and the upper part of the body to each other.
- the reinforcements 4 also comprise reinforcements 122 which connect the transverse walls 109 of the body to each other and which in this case have a connection direction perpendicular to these walls 109 and to the direction connection of reinforcements 121.
- the reinforcements 4 of the tank 1 of Figure 7 thus extend by intersecting in two different directions of space, in this case D2 and D3, forming a bi-axial network of reinforcements 4.
- FIG 8 shows another example of tank 1 according to the invention which is described below only according to its differences compared to tank 1 of Figure 7, the preceding description applying by analogy.
- the upper part of the body comprises two upper walls 131 and 132 facing the lower wall 101, two lower longitudinal walls 133 and two upper longitudinal walls 134.
- the upper walls 131 and 132 are parallel to the lower wall 101.
- the distance along D2 between the lower wall 101 and the upper wall 131 is greater than the distance along D2 between the lower wall 101 and the upper wall 132, forming a stepped tank.
- the maximum height of tank 1 that is to say the distance along D2 between the lower wall 101 and the upper wall 131, can be approximately 400 mm.
- the lower longitudinal walls 133 are substantially parallel to the directions D2 and D3 and are spaced apart from each other in the direction DI so as to define a length of the tank 1.
- One of the upper longitudinal walls 134 provides the connection between one of the lower longitudinal walls 133 and the upper wall 131, while the other upper longitudinal wall (not visible in Figure s) ensures the connection between the upper wall 131 and the upper wall 132.
- the upper longitudinal walls 134 face each other and extend along a plane slightly oblique to the plane D2-D3.
- the reinforcements 4 include reinforcements 121 similar to the reinforcements 121 of the tank in Figure 7, that is to say reinforcements 121 connecting the lower wall 101 and the upper part of the body to each other, as well as reinforcements.
- reinforcements 122 similar to the reinforcements 122 of the tank in Figure 7, connecting the transverse walls 109 of the body to each other.
- THE reinforcements 4 also include reinforcements 123, some of which connect the two lower longitudinal walls 133 to each other and others which connect the two upper longitudinal walls 134 to each other.
- the reinforcements 4 of the tank 1 of Figure 8 thus extend crisscrossing in three different directions of space, in this case DI, D2 and D3, forming a tri-axial network of reinforcements 4.
- the invention makes it possible to create polymorphic reservoirs which can include a network of multi-axial/multi-directional reinforcements.
- this may comprise a peripheral layer comprising intertwining of metal filaments such as copper, in order to protect the tank 1 against electrostatic charges.
- the tank 1 may comprise a dimensional control device formed by an interweaving of optical, inductive or laser-charged filaments allowing the detection of defects or failures generated during the life of the tank 1.
- certain wells formed during the production of the membrane can be used not to produce additional reinforcements but to fix the tank 1 to a vehicle, for example using fixing studs passing through these wells.
- the jacket 2 and/or the external envelope 6 of the reinforcement(s) 4 may be devoid of fibers, which makes it possible to reduce the cost, or on the contrary include fibers, for example to improve the adhesion of these elements. .
- a tank according to the invention can be used in a transport device other than a motor vehicle, for example in an aircraft or in a railway or naval vehicle.
