摘要： The invention relates to a method for producing a pressure accumulator (1), in particular for accumulating hydrogen in motor vehicles, wherein first of all an inner liner (3) of the pressure reservoir (1) is produced, preferably by means of a plastic blow molding process, wherein subsequently the inner liner (3) is provided, preferably braided, on the outside with a multi-ply reinforcing layer (9) including reinforcement fibers (8), and wherein the reinforcing layer (9) is then impregnated with a resin, preferably an epoxy resin, which, after curing, fixes the position of the reinforcement fibers (8) in the reinforcing layer (9). According to the invention the impregnation takes place from the contact region (K) of the outer surface of the inner liner (3) with the reinforcing layer (9) to the outer region of the reinforcing layer (9).
