Carbon fiber composite material |
| abstract |
A composite material includes: carbon fibers having an average fiber length of more than about 10 mm and about 100 mm or less; and a thermoplastic resin. The carbon fibers are substantially two-dimensionally-randomly oriented. The composite material includes a carbon fiber bundle (A) in a ratio of about 30 volume % or more and less than about 90 volume % to a total volume of the carbon fibers, the carbon fiber bundle (A) including the carbon fibers of a critical single fiber number defined by formula (1) or more. An average number (N) of the carbon fibers in the carbon fiber bundle (A) satisfies formula (2).n nCritical single fiber number=600/ D (1)n n6×10 4 /D 2 <N <2×10 5 /D 2 (2)n nD is an average fiber diameter (μm) of the carbon fibers. |
