Method for producing a three-dimensional fiber-reinforced composite material and a three-dimensional fiber-reinforced composite material

摘要

three-dimensional fiber reinforced composite material is a laminate comprising a plurality of fiber bundle layers stacked in a stacking direction, the fibers Tabaso is a laminate comprising a first and a second outermost layer, the matrix resin When provided with a lock yarn exit, and binding yarns that bind the fiber bundle layer. Binding yarn is missing a folded portion which is folded back through the outer lock yarn, and a first transverse thread portions and a second transverse thread portion continuous to the folded portion, the surface of the second outermost layer, the outermost layer of the second It has a surface layer yarn portion, the extending direction substantially orthogonal to the retaining threads missing along the surface. Surface thread portion has a bifurcated portion extending to the opposite direction from the second of the first cross-thread part on the surface of the outermost layer and the second cross-thread part. A bifurcated portion, a space surrounded by the fiber bundle of the second outermost layer adjacent to said bifurcated portion, the space between the first and respectively the fiber bundle adjacent to that of the second transverse thread portion, and a first transverse the space between the yarn portions second transverse thread portions, and the additive and the matrix resin is disposed.
