Abstract
A pressure container manufacturing method for manufacturing a pressure container by forming an outer shell made of a fiber reinforced composite material on a periphery of a liner, by: preparing a first fiber bundle which has a large diameter fiber bundle unimpregnated with a resin, and a second fiber bundle which has a small diameter fiber bundle and a thermoplastic resin covering the small diameter fiber bundle; forming a body on the periphery of the liner by braiding the first fiber bundle and the second fiber bundle with a braider; impregnating the first fiber bundle with the thermoplastic resin in the second fiber bundle which is heated and melted; and curing the thermoplastic resin to form the outer shell, wherein tension applied to the first fiber bundle is larger than tension applied to the second fiber bundle when forming the body and/or impregnating the thermoplastic resin.
