  • High performance tanks are understood to mean tanks optimized in terms of mass, such as those used in the transport industries in general, space transport in particular.
  • High performance composite tanks intended for the storage of pressurized fluids are generally designed by separating the functions of sealing and mechanical resistance to pressure.
  • These tanks comprise a shell in principle thin made of metal or polymer called a "liner" which is responsible for ensuring the confinement of the fluid and in particular the sealing and / or the protection of the composite material wall of the tank vis-à-vis. fluid.
  • this shell is thin because it does not normally have a structural mechanical function and we seek to minimize the masses .
  • These reservoirs further comprise a coil of composite fibers which are then deposited by filament coil on the liner.
  • the role of this coil is to ensure the mechanical strength under pressure of the reservoir.
  • the emptying operations result in compression of the liner by the composite.
  • the liner may have a sufficient thickness to withstand this compression without buckling due to the technological minimum that can be used and the use of the liner as winding tool.
  • the total deformation of the liner linked on one side to the composite and on the other to the base, can become very significant.

  • a material with a low coefficient of friction is applied to said annular junction region 5, between the tank body and the base, surrounding the base before winding the composite body and gluing the liner and the composite body.
