PRESSURE VESSEL AND PRODUCTION METHOD THEREFOR

摘要

PROBLEM TO BE SOLVED: To solve the problem of increase in the mass and volume of a pressure vessel due to the presence of a protective layer.SOLUTION: A second protective member (62) protects the thin-walled section of a second panel section (92) by covering the thin-walled section and the periphery thereof. The thin-walled section is the part where the wall thickness of a reinforcement layer (20) is thin. The second protective member (62) has a two-layer structure in which the inner layer is molded from polyurethane and the outer layer is molded from a material in which expanded graphite has been mixed into polyurethane.
