Fiber structure, pressure container, and method of producing fiber structure

A method of producing a fiber structure, the fiber structure comprising:

• a liner including:
• a body portion having a cylindrical shape;
• a dome-shaped portion being continuous with at least one end of the body portion in an axial direction thereof;
• and
• a mouthpiece having a shape protruding from the dome-shaped portion in the axial direction of the body portion;
• and
• a fiber reinforcement base material formed of a fabric, the fiber reinforcement base material externally covering the body portion and the dome-shaped portion of the liner;
• warp yarns arranged in such a way that a direction in which a yarn main axis of each of the warp yarns in the body portion and the dome-shaped portion proceeds is a circumferential direction of the liner;
• and
• weft yarns forming the fabric with the warp yarns, wherein the method of producing the fiber structure comprising:
• arranging the warp yarns along the axial direction of the body portion and the dome-shaped portion of the liner;
• inserting each of the weft yarns into a shed formed between the warp yarns adjacent to each other in the axial direction of the liner;
• pressing the inserted weft yarn toward the liner by beating with a reed to weave the fabric out of the warp yarns and the weft yarns;
• and
• winding the woven fabric around the liner by rotating the liner around a center axis of the liner.
