<P>PROBLEM TO BE SOLVED: To provide a carbon fiber-reinforced resin composition with excellent mechanical properties, surface appearance, and the like, in particular, tensile strength, flexural moduli, appearance and designability. <P>SOLUTION: The carbon fiber-reinforced resin composition includes, based on 100 pts.wt. of (A) a thermoplastic polyamide resin, 20-160 pts.wt. of (B) a carbon fiber of 5.1 GPa or higher tensile strength. (A) The thermoplastic polyamide resin preferably comprises a repeating unit including (a1) a dicarboxylic acid component unit made of a terephthalic acid component unit, an aromatic dicarboxylic acid component unit other than that of terephthalic acid and/or an aliphatic dicarboxylic acid component unit of a 4-20 carbon atom number, and (a2) a diamine component unit made of an aliphatic diamine component unit and/or an alicyclic diamine component unit, and an aromatic diamine unit. <P>COPYRIGHT: (C)2013,JPO&INPIT |
