Patent ID: 11015047

Abstract:
To provide a fiber reinforced thermoplastic resin molded article having excellent impact strength and flexural strength, provided is a fiber reinforced thermoplastic resin molded article, including: a carbon fiber (A), an organic fiber (B) having a strand strength of 1500 MPa or more and, a thermoplastic resin (C), wherein the fiber reinforced thermoplastic resin molded article contains 5 to 45 parts by weight of the carbon fiber (A), 1 to 45 parts by weight of the organic fiber (B), and 20 to 94 parts by weight of the thermoplastic resin (C) with respect to 100 parts by weight of the total of the carbon fiber (A), the organic fiber (B), and the thermoplastic resin (C), wherein a ratio (Lco/lno) of the critical fiber length Lco of the organic fiber (B) to the number average fiber length lno of the organic fiber (B) is 0.9 or more and 2.0 or less, and wherein an interfacial shear strength between the organic fiber (B) and the thermoplastic resin (C) is 3.0 MPa or more and 50 MPa or less.
