Abstract (en)
[origin: CA3163645A1] Multilayer structure, intended for the transport, distribution and storage of hydrogen, comprising, from the inside outwards, at least one sealing layer and at least one layer of composite reinforcement. Said at least one innermost layer of composite reinforcement is rolled around said outermost sealing layer. Said sealing layer consists of a composition mainly comprising a thermoplastic polymer PA11, up to 15% by weight of impact modifier and up to 1.5% by weight of plasticizer. Said composition is devoid of an enucleating agent and a polyether block amide. One of the said composite reinforcement layers consists of material in the form of continuous fibres impregnated with a composition mainly comprising at least one polymer P2j. Said structure is devoid of an outermost layer and adjacent to the outermost layer of polyamide polymer composite reinforcement.
