Abstract: According to the present invention, a carbon-fiber preform for a carbon-fiber-reinforced plastic is formed from mutually intersecting warp and weft each of which including a carbon-fiber multifilament yarn. At least one of layer surfaces has fluff formed by cutting some of filaments of the carbon-fiber multifilament yarn, and a total fluff length of fluff formed on the warp and a total fluff length of fluff formed on the weft are not equal. The present invention provides a CFRP in which the delamination strength (interlaminar shear strength) is improved and that has a high strength.

Abstract: A reinforced fiber/resin fiber composite is provided in which the ratio and arrangement of a long fiber and a thermoplastic resin fiber included in an intermediate material are accurately controlled to simultaneously provide good impregnation characteristics of the long fiber and good interfacial characteristics between the long fiber and the thermoplastic resin. A reinforced fiber/resin fiber composite (50) is provided which is an intermediate material for a long-fiber reinforced thermoplastic resin structure. The reinforced fiber (15) is a long fiber extending in a longitudinal direction. The resin fiber (25) includes at least two thermoplastic resin fibers. The at least two thermoplastic resin fibers are arranged around the reinforced fiber (15) to surround the reinforced fiber (15).
