Abstract
A manufacturing method and a jig for a high-pressure tank includes a filament winding step in which a reinforcing shaft is inserted from a cap toward the other end of a liner, the axial length of the liner is fixed by the reinforcing shaft, and a fiber-reinforced resin is wound; and a thermal curing step in which the fixing of the reinforcing shaft to the other end of the liner is released so that the liner can change in the axial direction, and the fiber-reinforced resin is heated.
Claims5
A manufacturing method for a high-pressure tank including a liner having a filling space therein, and a reinforcing layer provided on an outer peripheral portion of the liner, the method comprising:
- a step of inserting a reinforcing shaft through a first end portion and a second end portion of the liner, fixing the reinforcing shaft to the liner, and fixing a length of the liner in an axial direction with the reinforcing shaft;
- a filament winding step of winding a fiber-reinforced resin around the outer peripheral portion of the liner while keeping an interior of the liner pressurized;
- a step of releasing a fixed state between the reinforcing shaft and at least one of the first end portion or the second end portion of the liner, thereby allowing the liner to be deformed in the axial direction;
- and
- a thermal curing step of heating the fiber-reinforced resin, in a state, in which the fixed state between the reinforcing shaft and the second end portion of the liner is released, and forming the reinforcing layer on the outer peripheral portion of the liner.
