High-pressure tank, vehicle including high-pressure tank, and method for manufacturing high-pressure tank

A method for manufacturing a high-pressure tank, the method comprising:

• preparing a liner having an internal space to store a fluid;
• preparing a porous member having a plurality of pores extending through the porous member in a thickness direction of the porous member;
• winding, around a surface of the liner, fibers impregnated with a thermosetting resin;
• arranging the porous member on the fibers;
• and
• thermally curing, by heating the liner having the porous member, the thermosetting resin impregnated in the fibers while causing the thermosetting resin to flow into the pores of the porous member;
• wherein the porous member includes a tubular mesh member having a mesh that defines the pores and surrounding an outer periphery of the liner,
• wherein the tubular mesh member has a stretching property in which a restoration force is generated when the tubular mesh member is stretched;
• and
• wherein the arranging step comprises
• attaching the tubular mesh member to an attachment device,
• inserting the liner having the fibers wound along a central axis of the attachment device into the tubular mesh member, and
• increasing the diameter of the tubular mesh member by the attachment device.
