Abstract:
A glass fiber reinforced polyamide resin composition comprising:(A) a polyamide resin; and, per 100 parts by weight thereof, (B) from 20 to 170 parts by weight of glass fibers; (C) from 0.01 to 5 parts by weight of a higher fatty acid amide compound; and (D) from 0.005 to 5 parts by weight of a higher fatty acid metal salt having an acid value of 0.5 mg KOH/g or less, further having a graft polyamide resin layer in an interface region between the polyamide resin (A) and glass fiber (B), wherein the graft polyamide resin layer has a modulus of elasticity of dynamic viscoelasticity function as calculated from an amplitude of response stress signal and a phase difference between a stimulation distortion signal and a response stress signal, each measured by a scanning viscoelasticity microscopic method, of at least larger than 1 when regarding the modulus of elasticity of the polyamide resin as 1, and wherein the graft polyamide resin layer has a thickness of from 1.0 &mgr;m to 20 &mgr;m.
