Abstract
A fiber structure body includes a several fiber layers stacked in a stacking direction and has a multi-axial orientation that includes axial-force directional yarns, orthogonal directional yarns, and intersecting yarns. The fiber structure body includes a flat plate portion and a bend portion that is bent to the flat plate portion and includes a surface intersecting with a surface of the flat plate portion. The axial-force directional yarns are made of continuous fiber of reinforced fiber. Of yarns that form the bend portion and are other than the axial-force directional yarns, yarns that form at least one axis of the bend portion are provided by spun yarns made of discontinuous fiber.
