<P>PROBLEM TO BE SOLVED: To provide a fiber-reinforced resin composition which is capable of providing a lightweight molded article that has high mechanical strength. <P>SOLUTION: A fiber-reinforced resin composition contains (A) a thermoplastic resin and (B) resin-impregnated filament bundles containing rayon fibers. The rayon fibers of the component (B) have a fiber diameter of 5-30 μm and an X-ray orientation degree of 86% or more. The resin-impregnated filament bundles are obtained by: tying 2,000-30,000 rayon fibers of the component (B) lined up in the longitudinal direction together in a bundle; integrating the bundle of the rayon fibers by impregnating the bundle with the thermoplastic resin of the component (A) in a molten state; and then cutting the integrated bundle into pieces 3-30 mm long. <P>COPYRIGHT: (C)2013,JPO&INPIT |
