  • Patent number: 8034876
    Abstract: There are provided an organic fiber-reinforced composite resin composition which is good in fiber dispersion, excellent in appearance, excellent in mechanical properties such as tensile elongation at break or impact strength and easy in thermal recycle; and a molded article obtained therefrom. An organic fiber-reinforced composite resin composition comprising (a) 60 to 95% by weight of a polyolefin resin (provided that an acid-modified polyolefin resin is excluded) and (b) 40 to 5% by weight (provided that (a)+(b)=100% by weight) of organic fiber to which a polar resin (provided that an acid-modified polyolefin resin is excluded) is attached, or an organic fiber-reinforced composite resin composition comprising organic fiber in an amount of 10 to 200 parts by weight based on 100 parts by weight of a polyolefin resin and having an Izod impact strength at ?40° C. of 10 kJ/m2 or more, and further, an organic fiber-reinforced composite resin molded article obtained therefrom.
