Title:
CARBON FIBER-REINFORCED RESIN COMPOSITE MATERIAL
Document Type and Number:
WIPO Patent Application WO/2016/152563
Kind Code:
A1
Abstract:
A carbon fiber-reinforced resin composite material which comprises carbon fibers containing carbon fiber bundles and a thermoplastic resin, wherein (1) the coefficient of variation (CV1) of the total fiber weight of the carbon fiber-reinforced resin composite material is 10% or less, (2) the coefficient of variation (CV2) of the volume fraction (Vf) of the carbon fibers, which is defined by formula (a), in the carbon fiber-reinforced resin composite material is 15% or less, and (3) the weight average fiber length of the carbon fibers is 1 to 100 mm.
Formula (a): volume fraction (Vf) the carbon fibers = 100 × (volume of the carbon fibers)/[(volume of the carbon fibers) + (volume of the thermoplastic resin)]
