Title:

THREE-DIMENSIONAL FIBER-REINFORCED COMPOSITE MATERIAL

Document Type and Number:

WIPO Patent Application WO/2014/030631

Kind Code:

A1

Abstract:

A three-dimensional fiber-reinforced composite material which comprises: a laminated body consisting of a plurality of fiber bundle layers that are laminated in the laminating direction, said fiber bundle layers comprising first and second outermost layers; a matrix resin; a first falling-off preventing yarn; a second falling-off preventing yarn; and a binding yarn. The binding yarn comprises: a folded part that is folded so that the binding yarn passes through the outside in the laminating direction of the first falling-off preventing yarn; first and second crossing yarn parts that are connected to the folded part and extend in the laminating direction between the first falling-off preventing yarn and the second falling-off preventing yarn in the laminated body; a surface layer yarn part that extends along the surface of the second outermost layer toward the direction roughly perpendicular to the second falling-off preventing yarn; and a bifurcated part that is formed on the surface of the second outermost layer and connected to the first crossing yarn part and the second crossing yarn part. The bifurcated part is formed by intercrossing the surface layer yarn part that extends in the opposite directions in the outside in the laminating direction of the second falling-off preventing yarn.
