Carbon-Fiber-Reinforced Resin Composite Material

Abstract

A carbon-fiber-reinforced resin composite material includes: carbon fibers including carbon fiber bundles and a thermoplastic resin, in which (1) a coefficient of variation (CV1) of a total areal weight of the carbon-fiber-reinforced resin composite material is 10% or lower, (2) a coefficient of variation (CV2) of a carbon fiber volume fraction (Vf) in the carbon-fiber-reinforced resin composite material which is defined by Expression (a) is 15% or lower, and (3) a weight average fiber length of the carbon fibers is 1 to 100 mm. Carbon Fiber Volume Fraction (Vf)=100×Volume of Carbon Fibers/(Volume of Carbon Fibers+Volume of Thermoplastic Resin) . . . Expression (a).
