    摘要: A long-fiber-reinforced polymer alloy resin composition (C) prepared by compounding a master batch (A) comprising a long fiber reinforcement (a2) having a length of 3-30 mm and contained in a polyamide resin (a1) matrix with a substantially polymer-alloyed resin diluent material (B) prepared by melt-kneading 45-20 wt.% of a crystalline polyolefin resin (b1) containing a crystalline olefin polymer (b11) modified with an unsaturated carboxylic acid (b12) and 55-80 wt.% of a polyamide resin (b2). In the composition (C), the content of the reinforcement (a2) is 10-60 wt.% and that of the polyolefin resin (b1) in the resin components (a1, b1 and b2) is 20-45 wt.%. The composition is excellent in tensile strength and particularly in repeated impact characteristics.

    摘要: Disclosed is a long fiber-reinforced columnar product (D) comprising a modified propylene crystalline resin (A) having been modified with either an organosilane compound, an unsaturated carboxylic acid or its acid anhydride, 10 to 60 % by weight (based on the composition) of a long fiber reinforcement (B) having a mean fiber length of 3 to 30 mm and a mean diameter of 3 to 21 µm, and 3 to 20 % by weight (based on the composition) of an elastomer (C), said long fiber reinforcement (B) being arranged in the major axis direction of the long fiber-reinforced columnar product (D) having a length substantially equal to the mean fiber length of the long fiber reinforcement (B). Injection molding of this long fiber-reinforced columnar product can provide a propeller fan which is not broken and has low rotation creep even at a high rotational speed, though such a high rotational speed is hardly attained in the case of a short fiber-containing resin material.
