FIBER-REINFORCED THERMOPLASTIC RESIN PREPREG, MOLDED BODY OF SAME, AND METHOD FOR PRODUCING FIBER-REINFORCED THERMOPLASTIC RESIN PREPREG

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 4.0 (No 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 the polyamide resin (C) in cases where only the polyamide resin (C) 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; and N 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.)
