Abstract (en)
[origin: WO2022214753A1] The present invention relates to a multilayer structure for transporting, distributing or storing a gas, in particular hydrogen, comprising, from the inside outwards, N composite reinforcement layer(s) which are deposited one on top of the other and consist of a fibrous material in the form of continuous fibres impregnated with a composition mainly comprising at least one semi-crystalline thermoplastic polymer P1, the melting point of which, measured in accordance with ISO 11357-3:2013, is greater than or equal to 150°C, or at least one amorphous thermoplastic polymer, the glass transition temperature of which is greater than 80°C, N being between 1 and 2000 layers, and an outer sealing layer (1) which adheres to the outermost composite reinforcement layer (2) and comprises a composition mainly comprising said at least one thermoplastic polymer P1, said composition of the outer sealing layer (1) being formed from at least the outermost composite reinforcement layer (2) adhering to the sealing layer, said outer sealing layer (1) having a thickness of at least 2 µm, the sum of the thicknesses of each composite reinforcement layer (2) and of the thickness of the sealing layer being equal to the sum of the thicknesses of said N layers prior to their deposition, less any porosities.
