Definitions

  • the technical sector of the present invention is that of tanks intended to contain compressed gas, for example natural gas to equip motor vehicles.
  • Gas powered vehicles are becoming more common around the world and there are known tanks containing liquefied petroleum gas (LPG) and tanks containing compressed natural gas (CNG).
  • Natural gas is generally methane.
  • Liquefied petroleum gas is generally at a pressure of 30.10 5 Pa.
  • natural gas is compressed to a pressure of around 300.10 5 Pa.
  • the technologies used in these two types of tanks are not the same.
  • CNG tanks are designed to withstand very high pressure and are most often metallic.
  • patent US-A-5443578 proposes a metallic steel tank. It is well known that these tanks, although resistant to pressure, are very heavy, of the order of 100 kg for a capacity of 100 liters. This mass requires a particular layout study on the passenger vehicle because their assembly supposes a reinforcement of the structure. It reduces the number of passengers and the payload and it can disrupt the road behavior of the vehicle. However, this type of tank remains cost competitive. This tank can only be used with difficulty on passenger vehicles without special arrangements.
  • Patent 09851962 proposes to improve this type of tank by providing a tank comprising an internal envelope of sufficient strength and an external honeycomb envelope. This tank is penalizing in terms of size.
  • Document DE-19935516 describes a reservoir made up of an internal metallic envelope and an external envelope made of material reinforced with fibers.
  • the concrete construction of this reservoir is not specified.
  • this kind of tank can be made from monobloc aluminum liners obtained by flow-forming processes. and / or repelling, the cost of which is high.
  • the patent WO9412396 describes a reservoir whose internal envelope consists of a polymer and whose external envelope consists of a matrix of non-metallic fibers impregnated with thermosetting resin.
  • This reservoir has the disadvantage of not being completely sealed and of being of high cost, but the advantage of having a reduced mass.
  • the object of the present invention is to provide a method for producing a reservoir containing compressed gas offering a compromise between mass and economically acceptable cost on a passenger vehicle.
  • the subject of the invention is therefore a method of manufacturing a reservoir for compressed gas, for example natural gas intended for a motor vehicle, of the type comprising an internal metallic envelope and an external envelope made of external composite material, characterized in that '' the metal casing is made from stainless steel sheets comprising a cylindrical trunk and two hemispherical end caps welded together and in that the outer casing is produced around said inner casing made of composite material by a filament winding.
  • motor vehicle By motor vehicle is meant vehicles of all types operating with this kind of fuel, such as private or utility vehicles, buses, trucks, construction equipment, etc.
  • the internal envelope has a thickness of the order of mm.
  • the filament winding is produced from a carbon wire impregnated with a resin of the epoxy type, possibly combined with wires of another nature.
  • At least one threaded end piece is attached by welding to the base of the hemispherical or elliptical caps.
  • one uses a carbon wire of diameter less than mm.
  • the invention also relates to a tank for a vehicle operating on compressed natural gas obtained according to the method.
  • the reservoir has an internal diameter of the order of 350 mm and a length of 1400 mm.
  • a very first advantage of the method according to the invention lies in the fact that the manufacture of the reservoir requires only the implementation of conventional welding and filament laying technologies. Another advantage lies in the fact that the manufactured tank can be incorporated into a vehicle without any particular modification.
  • FIG. 1 is an external view of the metal casing
  • FIG. 1 is a section through the tank.
  • the liner 1 of a tank that is to say the internal metal casing which mainly provides the seal.
  • This liner 1 comprises a trunk 2 of generally cylindrical shape and two hemispherical caps 3 and 4, these three elements being made of stainless steel.
  • the trunk 2 is made from a sheet of stainless steel with a thickness of the order of mm which is welded edge to edge longitudinally.
  • the caps 3 and 4 are identical and produced by stamping a sheet of stainless steel with a thickness of the order of mm.
  • the two caps 3 and 4 are then welded to the trunk 2.
  • the caps are provided with end caps 5 and 6 which can be threaded. These nozzles 5 and 6 make it possible to fix the liner 2 on the winding device on the one hand and to integrate the tank in a vehicle.
  • One of the end pieces can be hollow to communicate with the interior of the body to allow filling and feeding of the vehicle.
  • FIG 2 there is shown a reservoir 7 consisting of the liner 1 and an outer casing 8.
  • This casing 8 is produced as explained above by winding a carbon wire impregnated with a resin, for example an epoxy resin .
  • the carbon thread may possibly be combined with fibers of another nature.
  • the winding operation is in itself conventional and it is not necessary to describe it in detail.
  • the reservoir 7 is fixed to the winding machine by means of the nozzles and this machine is programmed in a conventional manner to produce a satisfactory winding of the wire on the liner both at the level of the body 2 and of the caps 5 and 6.
  • the wire carbon is a known type of wire having conventional characteristics in the production of filament wound.
  • the casing 8 is intimately linked to the internal casing and bears on the end caps.
  • Such an embodiment makes it possible to guarantee the resistance of the reservoir to an internal pressure of compressed gas service greater than 200 ⁇ 10 5 Pa.
  • the wire used is preferably made of carbon but one could use a “wire” of another nature, for example a metal wire , mineral or synthetic.
  • the mass is of the order of 40 Kg.
  • the tank according to the invention can be used not only to supply natural gas to vehicles , but it can also contain compressed air, hydrogen, and any other gas used in compressed form.
