PRESSURE VESSEL AND PRODUCTION METHOD THEREOF |
| 摘要 |
A second protective member (62) is provided to cover a thin wall portion and its periphery of a second tank head section (92), so as to protect the thin wall portion. The thin wall portion is a region of the second tank head section (92) in which a reinforcing layer (20) has a smaller wall thickness. The second protective member (62) has a double layer structure including an inner layer made of polyurethane and an outer layer made of a material mixture of polyurethane and expanded graphite. This structure suppresses the mass and the volume of a pressure vessel from being increased by the presence of a protective layer. |
