Pole-cap-reinforced pressure vessel

Abstract

The invention relates to a pressure vessel (1) with reinforced pole caps (22) and a method for producing such a pressure vessel (1), which comprises an inner vessel (2) of a cylinder-shaped central part (21) and two dome-shaped pole caps (22) closing the central part (21) on both sides and an outer layer (3) wound on the inner vessel (2) for the reinforcement of the inner vessel (2) against a pressure load, wherein the outer layer (3) comprises at least one pole cap reinforcement layer (31) and a pressure vessel reinforcement layer (32) of fiber composite material (FVM), wherein the pole cap reinforcement layer (31) at least partially covers the pole caps (22) and the pressure vessel reinforcement layer (32 )covers the pole caps (22) and the central part (21) and a contour-stable preform (5) is arranged as the pole cap reinforcement layer (31) on at least one of the pole caps (22), preferably on both pole caps (22)
