HIGH-PRESSURE GAS TANK PRODUCTION METHOD

摘要

The FW technique is employed to suppress a non-fiber-wound space from being left during formation of a fiber layer for reinforcement on a liner. A process of forming a fiber-reinforce resin layer 20 on a liner 10 winds and fixes a winding start end fiber Ws of a resin-impregnated carbon fiber W on a fiber fixation flange 114, which is away from the top of a dome section 10b (step S100). The process subsequently forms an innermost helical layer 20H1 from the winding start end fiber Ws extended from the fixation position and the subsequently fed resin-impregnated carbon fiber W (step S110). The process subsequently forms an inner hoop layer 20F1 over the innermost helical layer 20H1 and cuts the winding start end fiber Ws extended from the fixation position of the fiber fixation flange 114 at a position on the periphery of the top of the dome section 10b, prior to formation of a subsequent second helical layer 20H2.
