Abstract: A resin composition includes 90 to 50% by weight of (A) a polyamide having 7 or more average carbon atoms per amide functional group and containing no aromatic ring; 10 to 50% by weight of (B) a polyamide having an aromatic ring and being crystalline, based on 100% by weight of the total of the component (A) and the component (B); and 5 to 75 parts by weight of (C) a carbon fiber, based on 100 parts by weight of the polyamide including (A) and (B).

Abstract: Disclosed is a polyamide resin composition, a method for producing the composition, and articles from the composition. The polyamide resin composition polyamide resin composition is formed by melt-kneading (A) 100 parts by weight of nylon resin, and (B) 5-150 parts by weight of at least one of a non-fibrous inorganic filler having an average particle diameter of 0.05-10 &mgr;m and a fibrous inorganic filler, excluding glass fiber, having a fiber diameter of 0.05-10 &mgr;m. In the polyamide resin composition, an amount of a polyamide resin component deposit remaining on the inorganic filler when the inorganic filler is recovered by dissolving the polyamide resin composition into hexafluoroisopropanol is at least 4 g/m2 per unit surface area of the inorganic filler measured by a BET method. The nylon resin composition is excellent in rigidity and toughness and particularly excellent in high-speed surface impact fracture characteristic.

Abstract: A composite particulate material for resin reinforcement which comprises an inorganic particulate material (A) and an elastic polymer (B) having a glass transition temperature of -10.degree. C. or below and also having functional groups capable of forming chemical bonds with resins to be reinforced, said components (A) and (B) accounting for 50-99 wt % and 50-1 wt %, respectively, of their total amount. A process for producing said composite particulate material. A reinforced resin composition incorporated with said composite particulate material. The resin composition yields molded articles which are improved in mutually contradicting properties (that is, impact strength vs. stiffness and elongation at break vs. heat resistance) and which have mechanical properties with less anisotropy. It offers good characteristic properties which are hardly attained by conventional engineering plastic materials.
