Abstract

A fiber reinforced thermoplastic resin molded article includes 5 to 45 parts by weight of carbon fibers (A), 1 to 45 parts by weight of organic fibers (B), and 10 to 94 parts by weight of a thermoplastic resin (C), based on 100 parts by weight of the total amount of the carbon fibers (A), the organic fibers (B), and the thermoplastic resin (C). The carbon fibers (A) in the fiber reinforced thermoplastic resin molded article have an average fiber length (L) of 0.3 to 3 mm. The organic fibers (B) in the fiber reinforced thermoplastic resin molded article have an average fiber length (L) of 0.5 to 5 mm, and a number average fiber diameter (d) of 35 to 300 μm. The fiber reinforced thermoplastic resin molded article is excellent in impact strength and surface appearance.
