Abstract
A three-dimensional fiber-reinforced composite includes a laminate having fiber bundle layers that are laminated in the laminating direction and include first and second outermost layers, primary and secondary retention yarns, and a binding yarn. The binding yarn includes a fold-back section, primary and secondary traverse yarn sections, a surface yarn section that extends along the surface of the second outermost layer in the direction substantially perpendicular to the secondary retention yarn, and a bifurcated section that is formed on the surface of the second outermost layer and connected to the primary and secondary traverse yarn sections. The bifurcated section is formed by crossing the surface yarn section that extends in opposite directions in the outside in the laminating direction of the secondary retention yarn.
