A manufacturing method of three-dimensional textiles strengthening compound material and three-dimensional textiles strengthening compound material

Japanese Patent JP5920471

B2

A three-dimensional fiber-reinforced composite is provided with 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; a retention yarn, and a binding yarn for binding the fiber bundle layers. The binding yarn has a fold-back section folded back through the outside of the retaining yarn, first and second traverse yarn sections continuous with the folded-back section, and a surface-layer yarn section that extends on the surface of the second outermost layer in a direction substantially perpendicular to the retention yarn along the plane of the second outermost layer. The surface layer yarn section has bifurcated sections extending in opposite directions from the first traverse yarn section and the second traverse yarn section 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 traverse yarn section and the second traverse yarn section.
