Title:
GAS TANK AND PROCESS FOR PRODUCING GAS TANK
Document Type and Number:
WIPO Patent Application WO/2010/004813
Kind Code:
A1
Abstract:
A gas tank is provided which can ensure high gas barrier properties even with respect to gases having a small molecular size, such as hydrogen gas.
In producing a high-pressure gas tank comprising an FRP layer and a resin liner disposed inside the FRP layer, an oxide layer is formed on the inner surface of the resin liner. Reinforcing fibers are wound on the outer surface of the resin liner by the filament winding method, and air is enclosed inside the resin liner before the winding. In the subsequent step of forming an FRP layer by thermally curing the reinforcing fibers, the inner surface of the resin liner is thermally oxidized to form an oxide layer.
