Fiber-reinforced resin composition |
摘要 |
A fiber-reinforced resin composition which is capable of providing a light-weight molded article that has a high mechanical strength. The 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. |

1. A fiber-reinforced resin composition comprising a resin-impregnated long fiber bundle including (A) a thermoplastic resin and (B) a rayon fiber, wherein
the rayon fiber of component (B) has a fiber diameter of 5 to 30 μm and an X-ray orientation degree of 90% or more, and the resin-impregnated long fiber bundle is obtained by impregnating a bundle of 2,000 to 30,000 rayon fibers of component (B) in a state where the rayon fibers are arranged in the longitudinal direction, with the thermoplastic resin of the component (A) in a molten state to thereby form an integrated bundle, and then cutting the integrated bundle into a length of 3 to 30 mm. |
