Abstract:
A fiber reinforced thermoplastic resin molding material includes a carbon fiber reinforced thermoplastic resin molding material, comprising 5 to 45 parts by weight of carbon fibers, 94 to 35 parts by weight of a thermoplastic resin, and 1 to 20 parts by weight of a compound having a melt viscosity lower than the thermoplastic resin based on 100 parts by weight of the total amount of the carbon fibers, the thermoplastic resin, and the compound having a melt viscosity at 200° C. lower than that of the thermoplastic resin, wherein the thermoplastic resin is contained at an outer side of a composite obtained by impregnating the carbon fibers with the compound, and the length of the carbon fibers and the length of the carbon fiber reinforced thermoplastic resin molding material are substantially the same.
