| description | A random mat including carbon fibers and a thermoplastic resin, wherein a pressure applied when molding can be reduced and high mechanical strength is obtained when a shaped product of fiber reinforced composite material is formed, is provided. A random mat including carbon fibers having an average fiber length of from 3 mm to 100 mm and a thermoplastic resin, wherein a fiber areal weight of the carbon fibers is from 25 to 10,000 g/m 2 , a proportion of carbon fiber bundles (A) constituted by single carbon filaments of a critical single fiber number or more defined by the formula (1) to the total amount of fibers in the random mat is from 40 to 99 Vol%, and an average number (N) of fibers in the carbon fiber bundles (A) satisfies the formula (2): Critical single fiber number = 600 / D 2.0 × 10 5 / D 2 ¤ N < 8.0 × 10 5 / D 2 wherein D is an average fiber diameter (µm) of carbon fibers. |
