FIBER-REINFORCED POLYAMIDE RESIN MATERIAL

摘要

Provided is a fiber-reinforced polyamide resin material which has high stiffness, low water absorbability and excellent moldability and can be molded into a molded article having excellent mechanical properties. A fiber-reinforced polyamide resin material comprising 100 parts by mass of a polyamide resin (A) that is a polycondensation product of a diamine and a dicarboxylic acid and 5 to 300 parts by mass of carbon fibers (B), wherein xylylene diamine makes up 70 mol% or more of the diamine, a linear aliphatic dicarboxylic acid having 4 to 20 carbon atoms makes up 50 mol% or more of the dicarboxylic acid, the concentration of a terminal amino group ([NH2]) in the polyamide resin (A) falls within the range represented by the formula: 5 < [NH2] < 150 (unit: µeq/g), and each of the carbon fibers (B) has a compound (C) having reactivity with an amino group on the surface thereof.
