Abstract:
1. A random mat comprising: carbon fibers having an average fiber length of 5 to 100 mm; and a thermoplastic resin, wherein a fiber areal weight of the carbon fibers is from 25 to 3,000 g/m the random mat comprises a carbon fiber bundle (A) in a ratio of from 30 vol % to less than 90 vol % to a total amount 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, and an average number (N) of single carbon fibers in the carbon fiber bundle (A) satisfies formula (2): wherein D is an average single fiber diameter (μm) of the carbon fiber bundle (A).
