Hydrogen tank body and method of producing the same, and hydrogen tank and method of producing the same
A hydrogen tank body includes a base layer formed of a synthetic resin selected from the group consisting of silicon resin, polyphenylene sulfide, polybutylene terephthalate, polyvinyl chloride, polypropylene, polyethylene, and polycarbonate, and a liner layer formed of hydrogen impermeable resin, on an inside wall surface of the base layer.
1. A method of producing a hydrogen tank body, the method comprising:
forming a base layer of the hydrogen tank body, using a synthetic resin selected from the group consisting of silicon resin, polyphenylene sulfide, and polyvinyl chloride; and
forming a liner layer along an inside wall surface of the base layer, by subjecting a hydrogen impermeable resin to blow molding, using the base layer as a mold form for the blow molding.
2. The method according to claim 1 , wherein the base layer is formed by subjecting the synthetic resin to injection molding.
3. The method according to claim 1 , wherein the hydrogen impermeable resin is polyamide 6.
4. The method according to claim 1 , wherein the synthetic resin is the silicon resin.
5. The method according to claim 4 , wherein the silicon resin is dimethylpolysiloxane.
6. A method of producing a hydrogen tank, the method comprising:
forming a hydrogen tank body by the method according to claim 4 ; and
forming a pressure resistant layer by directly winding carbon fiber reinforced resin around the hydrogen tank body.
7. The method according to claim 6 , wherein the silicon resin is dimethylpolysiloxane.
