Abstract
A three-dimensional fiber-reinforced composite includes a laminate having a plurality of fiber bundle layers that are layered in a lamination direction and include first and second outermost layers, a matrix resin; and a binding yarn. The binding yarn has first and second traverse yarn sections, and a surface-layer yarn section. The surface layer yarn section has bifurcated sections extending in opposite directions from the first and second traverse yarn sections on the surface of the second outermost layer. An additive and the matrix resin are arranged in a space enclosed by the bifurcated sections and the fiber bundles of the second outermost layer adjacent to the bifurcated sections, and also in a space between each of the first and second traverse yarn sections and fiber bundles adjacent thereto, and in a space between the first and second traverse yarn sections.
