A fabric laminate used as a reinforcing base material of a fiber-reinforced composite is constituted by laminating fabrics having warp yarns and weft yarns. Each warp yarn has a diameter-changing portion, in which the diameter of the yarn gradually changes in the yarn longitudinal direction in the vicinity of one end in the yarn longitudinal direction of the warp yarn.

Fabric for fiber reinforced composite material and fiber reinforced composite material

This fiber wound body has a plurality of reinforcing fiber yarns wound around a winding axis, each of the reinforcing fiber yarns having a thickness gradient portion in which the fiber content is uniform along the longitudinal direction of the yarn and the thickness gradually changes.

Fiber wound body, fiber-reinforced resin material, and method for manufacturing fiber wound body

A fiber-reinforced composite material () is constructed by laminating a plurality of fiber bundle layers formed of a reinforced fiber to form a laminated fiber bundle layer and further impregnating the laminated fiber bundle layer with a matrix. At either side of a neutral surface (), the number of +&#x3b8; layers which are fiber bundle layers having a fiber orientation angle of +&#x3b8; and the number of &#x2212;&#x3b8; layers which are fiber bundle layers having a fiber orientation angle of &#x2212;&#x3b8; are the same, the order of laminating the fiber bundle layers is inversely symmetrical with respect to the standard surface, and the number of other fiber bundle layers disposed between the +&#x3b8; and &#x2212;&#x3b8; layers at either side of the standard surface is the same.
