    摘要: A fiber-reinforced thermoplastic resin prepreg that is a fiber-reinforced polyamide prepreg which contains (A) reinforcing fibers, (B) a sizing agent and (C) a polyamide resin, and wherein the sizing agent (B) and the polyamide resin (C) satisfy the following condition. N m /N 0 m is the average of torques necessary for maintaining the number of revolutions of a roller type blade at 100 rpm/15 minutes, said average representing the fluidity of a mixture, which is obtained by mixing the sizing agent (B) and the polyamide resin (C) at 3:100 (mass ratio), in cases where the mixture is filled into a mixer having the roller type blade and heated and melted at a temperature that is higher than the melting point of the polyamide resin (C) by 30°C.)

    摘要: Provided are: chopped carbon fiber bundles which have high fluidity without decreasing the dispersibility of carbon fibers and the physical properties of a molded product; and a method for producing chopped carbon fiber bundles with high productivity. Chopped carbon fiber bundles, each of which contain a carbon fiber bundle having a total fineness of from 25,000 dtex to 45,000 dtex (inclusive) and a sizing agent in an amount of from 1% by mass to 5% by mass (inclusive) relative to the total mass of the chopped carbon fiber bundle. The length (L) of each chopped carbon fiber bundle along the fiber direction of the carbon fiber bundle is from 1 mm to 50 mm (inclusive); the ratio of the longest diameter (Dmax) to the shortest diameter (Dmin) of a cross section perpendicular to the fiber direction of each chopped carbon fiber bundle, namely Dmax/Dmin is from 6.0 to 18.0 (inclusive); and the orientation parameter of the single fibers present in the surface of each chopped carbon fiber bundle is 4.0 or less.
