Single-layer or multilayer structure for transporting, storing or distributing compressed gas

A method for transporting, storing, or distributing compressed gas, comprising:

• preparing an envelope of a structure from at least one composite reinforcing layer consisting of a fibrous material in the form of continuous fibers impregnated with a composition comprising at least one ductile thermoplastic polymer, having a glass transition temperature (Tg) measured according to the standard ISO 11357-3:2013, said Tg being less than or equal to the operating temperature To, or said Tg being greater than the operating temperature To with |To−Tg|≤+120° C.,
• said composite reinforcing layer having, after consolidation, a transverse breaking strain greater than the breaking strain of said fibers at the operating temperature and at the strain rate representative of the use,
• to constitute the envelope of a structure for transporting, storing or distributing compressed gas;
• inserting compressed gas into the envelope;
• and
• transporting, storing, or distributing the compressed gas.
