Abstract
A high-pressure tank includes a cylindrical portion including a fiber-reinforced resin and a dome portion including a fiber-reinforced resin. The cylindrical portion includes an axial fiber layer including a fiber oriented in a center axis direction of the high-pressure tank, and a circumferential fiber layer including a fiber oriented in a circumferential direction of the high-pressure tank. An end portion of the axial fiber layer and an end portion of the dome portion are joined to each other.
Claims6
A high-pressure tank comprising:
- a cylindrical portion including a fiber-reinforced resin;
- and
- a dome portion including a fiber-reinforced resin, wherein
- the cylindrical portion includes
- an axial fiber layer including a fiber oriented in a center axis direction of the high-pressure tank, and
- a circumferential fiber layer including a fiber oriented in a circumferential direction of the high-pressure tank, and
- an end portion of the axial fiber layer and an end portion of the dome portion are joined to each other.
A method for manufacturing a high-pressure tank including a cylindrical portion including a fiber-reinforced resin and a dome portion including a fiber-reinforced resin, the method comprising:
- (a) a step of preparing an axial fiber layer included in the cylindrical portion, the axial fiber layer including a fiber oriented in an axial direction of the high-pressure tank, and the dome portion;
- (b) a step of forming a joined body by joining an end portion of the axial fiber layer and an end portion of the dome portion to each other;
- and
- (c) a step of forming a circumferential fiber layer including a fiber oriented in a circumferential direction of the high-pressure tank, on an outer side or an inner side of the axial fiber layer.
