Abstract (en)
[origin: CA3221459A1] Disclosed is a multilayer structure for transporting, distributing and storing hydrogen, the structure comprising, from the inside to the outside, at least one sealing layer (1) and at least one composite reinforcing layer (2), the innermost composite reinforcing layer being wound around the outermost adjacent sealing layer (1), the sealing layers consisting of a composition predominantly comprising: at least one semi-crystalline, aliphatic thermoplastic polyamide polymer P1i, i=1 to n, n being the number of sealing layers, the Tf of which, as measured according to ISO 11357-3: 2013, is greater than 200°C, with the exception of one polyether block amide (PEBA), said thermoplastic polyamide polymer being a polyamide having an average number of carbon atoms per nitrogen atom of 7 to 9, up to 30% by weight of impact modifier relative to the total weight of the composition and up to 1.5% by weight of plasticiser relative to the total weight of the composition, the composition being free of nucleating agent, the at least one thermoplastic polyamide polymer of each sealing layer being able to be identical or different, and at least one of the composite reinforcing layers consisting of a fibrous material in the form of continuous fibres impregnated by a composition predominantly comprising at least one polymer P2j, the polyamide polymer layer being the outermost layer and adjacent to the outermost composite reinforcing layer.
