PROBLEM TO BE SOLVED: To provide a fiber structure capable of suppressing a variation in density and a variation in thickness of a weave texture, a fiber-reinforced composite material, a method for producing a fiber structure, and a method for producing a fiber-reinforced composite material.SOLUTION: The fiber structure 11 has a cylindrical structure including a first cylindrical part 12 and a second cylindrical part 13 that is continuous with the first cylindrical part 12 and has a longer peripheral length than the first cylindrical part 12. The fiber structure 11 includes a fabric in which a plurality of first axial direction yarns 21 that extend in a direction parallel to an axial direction over the whole length of the first cylindrical part 12 and the second cylindrical part 13 in the axial direction, and a circumferential yarn 22 that spirally extends along a circumferential direction of the first cylindrical part 12 and the second cylindrical part 13 and over the whole length in the axial direction are weaved. The fiber structure 11 includes a second axial direction yarn 23 that is weaved therein, extends between the first axial direction yarns 21 in the second cylindrical part 13 in the axial direction and is provided over a part of the whole length in the axial direction of the second cylindrical part 13. |
