Abstract:
There is provided a shaped product made of a fiber-reinforced composite material including reinforcing fibers having an average length of 5 mm or more and 100 mm or less and a thermoplastic resin, in which a volume fraction of reinforcing fibers (Vf=100×volume of reinforcing fibers/(volume of reinforcing fibers+volume of thermoplastic resin)) is 5 to 80%, grains are formed on a surface of the shaped product, and a ratio of a reinforcing fiber bundle (A) including the reinforcing fibers of a critical number of single fiber or more, the critical number defined by Formula (1), to the total amount of the reinforcing fibers is 20 Vol % or more and 99 Vol % or less: Critical number of single fiber=600/D (1) (wherein D is an average fiber diameter (μm) of single reinforcing fiber).
