PRESSURE VESSEL AND METHOD FOR WINDING FILAMENT

摘要

Provided are a pressure vessel and a method for winding a filament which can make the thickness of a reinforcement layer uniform. The pressure vessel includes: a liner (2) having a hollow portion; and a reinforcement layer (4) covering the periphery of the liner (2). The reinforcement layer (4) comprises bands (11) of reinforced fiber laminated and wound around the liner (2), each of the layers of the reinforcement layer (4) having a lap portion (21, 22) formed by overlapping end portions of the adjacent bands (11), wherein the end portion of at least one of the adjacent bands (11, 11) in the lap portion (21, 22) is formed thinner than the other portions of that band (11).
