Definitions
- Textiles and fibrous structures are obtained by different fiber forming techniques.
- the main ones are: knitting, weaving, braiding, fiber placement, glazing and filament winding.
- the technique, the production parameters and the type of fibers used depend on the characteristics sought.
- Fibers shape, mechanical, electrical, surface appearance, fitness or impregnation ability, injection
- the nature of the fibers that can be used is very varied: natural fibers, organic fibers, mineral fibers or ceramics (glass, carbon, silicon carbide, basalt, ).
- Fibrous structures are generally used as reinforcement of composite materials (hulls, panels and structures, tanks, ...) but also have some direct applications (filtering or heating fabrics, braided cables, insulating knits, ).
- the braiding presents the peculiarities of a very great flexibility of geometrical design of the thread paths (generic term) of the structures, a good dimensional stability and good properties mechanical properties (rigidity, torsion behavior, damage resistance) of the structures obtained as well as the possibility of directly producing complex shapes (braiding on a mandrel) with a high level of fibers.
- This technique is, however, a little less used than weaving or knitting, because of its relative slowness and the lower mechanical properties of composites in compression.
- Braiding has many similarities with filament winding. It does not make it possible to obtain such high fiber levels, but allows more complex parts to be obtained and better impact behavior. Both techniques can sometimes be used in a complementary way to make objects.
- Textile braids are fibrous architectures obtained by interlacing of threads (threads, rovings, ribbons or bundles of threads).
- the dispositions of the Sons relative to each other are defined by the form and characteristics of the object that one wishes to obtain.
- the simplest braid that can be made, still called mat consists of only three Sons where, alternatively, one of the two outer Sons comes to take the place of the middle one by intercrossing, which leads each Wire to pass periodically in the center, one side then the other of the braid.
- Braids consisting of a larger number of threads are made on the same principle of interlacing, but with, so generally, Sons who follow the same direction for a longer distance.
- "2-D" braids consist of biaxial and triaxial braids.
- the biaxial braids consist of two groups of wires which intersect each other with an angle of + ⁇ , where ⁇ is defined as the braiding angle.
- Figure 1 is a representation of a biaxial braid consisting of a first group of son 1 and a second group of son 2 which intersect.
- the braiding angle ⁇ can vary between about 5 ° and 85 °, which are the practical limits of realization, between a braiding axis x and a tilting axis y.
- Figure 2 is a representation of a triaxial braid consisting of a first group of wires 3, a second group of wires 4 and a third group of wires 5 aligned in the braiding direction.
- the interleaving patterns are defined by two numbers: the number of Sons above which a thread of the opposite group passes and then the number of Sons below which it passes.
- the main reasons used are (1,1) (diamond braiding), (2,2) (normal braiding), (3,3) (Hercules braiding).
- the braiding thickness is constant and equal to the thickness of 2 wires (biaxial).
- the ratio of the diameters must remain between about 1 to 3, corresponding to an angle vary between 20 ° and 70 °. It should be noted, however, that the mechanical strength is not the same in areas of different diameters and also varies by a factor of 1 to 3.
- the tubular braids are obtained by braiding or directly on a liner (or envelope) constituting the part to be obtained, or on a mandrel. Thick structures are made by stacking several layers of braids (possibly different patterns) on top of one another.
- the "3-D” braids are an extension of the “2D” braids, obtained with the simultaneous braiding of several layers of “2D” braids having a periodic link from layer to layer. This type of texture is still known by the name of "interlock braid”. This makes it possible to obtain greater thicknesses, bonds between the layers (leading to better mechanical properties, such as better resistance to delamination), and more complex and precise shapes.
- Braiding is a traditional textile technique, very old (1748, Thomas Wadford's loom), originally used to make ropes, laces or tube reinforcements.
- Figure 3 shows the block diagram of a circular braiding machine, as described in "Handbook of Composite Reinforcements" by Y. Ed. Lee et al.
- a 2D braider that can be either vertical or horizontal, consists of a set of spindles 11 (wire reel stands) that move within a guide path defined on a table and according to a braiding plane 12.
- the spindles follow paths waving at the periphery of the circular table, half in one direction of the circle, the other half in opposite direction, the two paths interleaving as shown in Figure 4.
- a rectilinear displacement system 14, perpendicular to the braiding table, and synchronized with the movement of the spindles, allows to receive the braid 13, possibly on a mandrel 15.
- Reference 16 represents the convergence zone of the braiding yarns.
- the reference 18 represents an axial yarn, the reference 19 representing an axial yarn guide.
- the ratio of the speed of movement of the spindles relative to that of displacement of the mandrel defines the angle of braiding.
- the ratio of the number of reels with respect to the number of crossings defines the type of braiding pattern produced.
- the addition of fixed coils makes it possible to obtain triaxial braids. If the spindles do not make complete turns but turn back after a certain distance, we obtain flat braids.
- the spindles comprise uniform tensioning systems, allowing the tensioning or the compensation of the yarns (the distance from a spindle to the convergence zone on the braid being not constant), to obtain braids of uniform patterns and desired compactness.
- the thickness of a layer is equal to twice the thickness of a wire.
- 3D braiders There are two types of 3D braiders. The first type is called rectangular, with an alternating movement in two directions, and to obtain “Cartesian” braids. The second type is circular, with an alternating movement in the radial and circular directions, leading to "polar" braids. Obtaining profiles of different cross-sectional shapes is possible by a predetermined positioning of the spindles on the machine in the initial state. Hollow sections are obtained by polar braiding, massive sections by Cartesian braiding. One can refer to this subject in the article N 2511 of the Techniques of the Engineer, already cited, and in "Handbook of Composites" by G. Lubin et al., Springer, 1998.
- Structural composite materials consist of fibrous reinforcements, such as braids, and a matrix, which is the material between the fibers (and gives cohesion to the material). They are characterized by different types of matrices:
- thermoplastic or thermosetting thermoplastic or thermosetting
- US Pat. No. 7,204,903 describes, very briefly, an original solution.
- the braiding is carried out on a cylindrical liner at the center and hemispherical (domes) at the ends. At least one domes has an insert at its end (pole).
- the braiding is carried out conventionally on the cylindrical part and, on the hemispherical part, up to the insert.
- the innovation lies in the fact that at this moment, instead of going back in the opposite direction, to make a second layer, the braiding is stopped and the coils turn (about 180 °), half in one direction, the other half in the other direction, which places the coils away from their original location.
- the braiding then resumes (next layer), following the reverse direction of the previous one.
- the advantage cited, compared to conventional braiding, is to avoid, during the transition of braiding from one layer to another, having to cut the son, or, when they have sufficient flexibility, to bend and fold them back.
- the manufacturing method employed leads, during the 180 ° rotation, in the hemispherical part, to every second layer which corresponds to placements of non-interconnected wires (equivalent to filament winding) and to a considerable thickness at level of the insert (the wires overlap against this one). It should be noted that no value or precision is given on the braiding itself, on the diameters of the cylinder or insert, whether in the description of the invention or the examples (the only value numeric is that of the angle of rotation between two braids).
- the teaching of this patent does not solve the closure at one end but only the integration of an insert. Moreover, the invention also does not provide a solution for the problem of small diameters.
- the document US 2008/0264551 describes the manufacture of composite tanks (cylinder and hemispherical bottoms) based on dry yarns (not impregnated with resin) for the storage of low or high pressure gas.
- the invention resides in the fact that the inner liner serves as a mold during the injection of the resin and also as a heating or cooling system during the polymerization.
- the braiding is performed by combining bi-axial or tri-axial braiding, on the faces of the domes, by folding and deforming the bi-axial braid and sealing the ends of the son by a means such as gluing. This method allows, according to the authors, a good control of the thickness and the contour.
- This system uses conventional braids and does not allow to have a continuity of the wires on the domes, since their ends are glued, nor closure based on wires.
- the document WO-A-89/05724 describes the production of a bottle of composite material, of moderate price, for the storage of high pressure gas.
- the ends of the bottles comprise two end pieces interconnected by a central rod, one of which serves to introduce or withdraw the gas.
- the body of the bottle consists of coaxial braids with a resin matrix.
- the tips may be frustoconical or hemispherical, metal or plastic.
- This document does not describe the braiding technique, it seems that the braids used are standard type.
- This invention also makes it possible to produce closed braids since the ends consist of inserts at the ends.
- ⁇ - ⁇ -0 487 374 discloses a pressurized gas storage tank consisting of filament wound wires and / or a braid. The tank is cylindrical with bottoms. There is no information on the braid used other than the fact that it serves as longitudinal reinforcement, so, a priori, on the cylindrical part. There is no description of closure by a continuous wire.
- US Patent 3,765,557 discloses a means for producing a pressure vessel which is made by filament winding where the standard wire is replaced by a braided wire. This patent is therefore not relative to the braiding technique and leads to very different structures. It is also conventional to obtain, by filament winding, a closed end, nevertheless with an extra thickness.
- US Patent 5,070,914 discloses a new woven architecture and its manufacturing means. The technique relies on weaving, with radially departing yarns and woven circumferential yarns, describing a spiral. These structures are based on a wire path in the form of a spiral and do not have cylindrical or axial symmetry, contrary to the invention which will be the subject of the appended claims.
- the shapes that can be obtained with braiding are solid forms (cables, strands), flat braids and tubular shapes, of varied and variable sections on the same part (for example air ducts for airplanes).
- For tubular braids there is a technical limitation that does not allow, at the ends of the braids, either to close them or to achieve a reduction of important section.
- the object of the present invention is to overcome this limitation, by allowing continuity of the fibrous architecture, keeping the same reinforcing wires between the closed part, or bottom, and the body, or tubular part, of the part .
- the subject of the invention is both a new type of tubular (or hollow) fibrous architecture closed at least at one end, and also its method or method of manufacture.
- the subject of the invention is therefore a method for manufacturing a tubular fibrous architecture, closed at one of its ends, the method comprising the following steps:
- each pair of coils being made by winding a first part of a yarn, from a first end of the wire, on a first coil of the pair and by winding a second portion of the wire, from the second end of the wire, on the second coil of the pair,

- the son of the coils, in step d), can be supported, positioned and maintained, so as to obtain a biaxial tubular architecture. They can also be supported, positioned and maintained, so as to obtain a triaxial tubular architecture.
- the job of step d) can be the job of step b).
- the Primary Structure can be made according to a technique chosen from weaving, braiding, topping and placement of threads. It can be a multi-layered, multidimensional or multi-directional texture, whose resulting threads are used to make the tubular part which is then multilayered.
- the tubular portion of the fibrous architecture can be made on the support, according to a technique chosen from weaving, braiding, topping and son placement. It can also be performed on the support, in multilayer, multidimensional or multidirectional texture modes.
- step d) can be chosen from a loom, a braiding machine, a loom and a loom son placement.
- the method may comprise an additional step g) during which the tubular portion of the fibrous architecture is extended on one end of the support to form a second bottom of the fibrous architecture.
- the additional step g) can be carried out until a second bottom closed by braiding, weaving, topping or wire placement.
- the making of the Primary Structure is carried out by incorporating into the Primary Structure at least one insert or at least one endpiece.
- the tubular portion of the fibrous architecture is produced by incorporating into the tubular portion at least one insert or at least one endpiece.
- the invention also relates to a tubular fibrous architecture having a tubular portion closed at at least one of its ends or bottom, in which:
- the tubular part consists of an architecture in which each thread, wick, ribbon or bundle of threads, hereinafter referred to generically as Thread, is derived continuously from the bottom,
- the junction between the bottom and the remainder of the tubular part has a continuity of all the wires and a transition of continuous geometry between the architecture of the bottom and that of the rest of the tubular part,
- the threads of the tubular portion intersect, preferably in a braiding or weaving mode.
- the bottom may consist of a structure obtained by layering web, bidirectional fabric, three-way fabric, multilayer fabric or multidirectional.
- the tubular portion may be constituted by superposition of web, tridirectional fabric, multilayer or multidirectional fabric.

- FIG. 5 illustrates a primary structure 30 with, for each wire 31 constituting it, the ends wound on two coils 32.
- the primary structure 30 constitutes a bottom for the tubular structure to be obtained.
- the primary structure 30 constituting the bottom of the tubular structure is disposed on one end of a tubular braiding mandrel 34 mounted on a braiding tray 35.
- the braiding is continued so as to coat the mandrel 34.
- FIG. 6 is a schematic diagram of the realization of the braiding of the tubular structure to obtain, from Sons derived from the Primary Structure constituting the bottom.
- the design of the primary structure requires that the portion made has the number of son (or pair of coils) corresponding to that desired for the tubular shape (determinable from the characteristics of the part that one wants to achieve). This can be seen in the article by Munro et al. cited above.
- first pairs of coils are made with a single wire (for each pair).
- the reels thus produced are placed on the spindles of the braiding machine with intersecting threads or without intersecting in the case of a single topping, to achieve the primary structure.
- FIG. 7 shows a first group of parallel wires 41 whose ends of each wire are wound on coils 42, a second group of parallel wires 43 and a third group of parallel wires 44, the groups of Son being arranged one on the other without intercrossing.
- the mandrel is then positioned on the machine and one of its ends is covered with the bottom of the tubular structure thus obtained. Then, the braiding can continue in a conventional way.
- the primary structure is first made with wires each of which is wound at each of its ends to a coil.
- the primary constitutive structure of the bottom can also be made directly on the form or liner to be coated, especially if the shape is moving away from a flat shape and is strongly curved (hemispherical for example).
- the primary structure can be realized by different techniques.
- the following three techniques can be cited.
- the wires are simply placed in three different directions (see Figure 7). This technique provides very good conformability and is simple to implement.
- Figure 8 illustrates this arrangement. There is shown a first group of parallel wires 51 arranged in a first direction and whose ends of each wire are wound on coils 52, a second group of parallel wires 53 arranged in a second direction and a third group of parallel wires 54 disposed in a third direction.
- This technique allows to keep a homogeneity of the structure.
- a third technique consists of a conventional weaving as illustrated in FIG. 9. It shows a first group of parallel wires 61 arranged in a first direction, and the ends of each wire are wound on coils 62, and a second group of parallel wires 63 arranged according to a second direction perpendicular to the first direction.
- Braiding made for the tubular part can be 2D (biaxial or triaxial) or 3D.

- the primary structure comprises three groups of wires arranged in different directions: a first group of parallel wires 71, a second group of parallel wires 73 and a third group of parallel wires 74.
- a first architecture incorporating son connected to coils, each of the son being connected at each of its ends to a coil
- First (first step) is carried out the primary structure of the bottom or closure (first layer).
- first layer For this, twelve Tyranno SA3 1600 filament fiber coils (diameters 7 ⁇ m) are unwound and rewound on twelve other coils in order to have twelve pairs of coils with a length of yarn between the two coils of about 1 m.
- a triaxial structure is realized with twelve pairs of coils distributed in a balanced way (according to the orientations 0 °, + 120 °, -120 °).
- the rest of the braid (first layer) is then made (second step).
- the bottom and coils are brought on the braider.

- the braiding is done in the same way as in the second step.
- the other two other layers are made in the same way.
