  • Gas tank and manufacturing method of gas tank
    Patent number: 9140408
    Abstract: A gas tank is provided which can ensure high gas barrier properties even with respect to a gas having a small molecular size, for example, a hydrogen gas. In a high-pressure gas tank comprising a resin liner inside an FRP layer, an oxide layer is formed on the inner surface of the resin liner. When a reinforcing fiber is wound around the outer surface of the resin liner by a filament winding process, air is beforehand enclosed inside the resin liner. Next, when the reinforcing fiber is thermally cured to form the FRP layer, the inner surface of the resin liner is thermally oxidized to form the oxide layer.
    Type: Grant
