摘要:
The present invention provides a glass fiber-reinforced thermoplastic resin composition in which a particular relationship is satisfied between the glass fiber content (W (parts by weight)) and the melt viscosity (·) of the thermoplastic resin composition at molding temperature as determined at a shear rate of 1,000 sec -1 . According to the present invention, there can be obtained a glass fiber-reinforced thermoplastic resin having increased strength and rigidity and excellent in practical characteristics such as impact resistance and antifreeze liquid resistance. In addition, molded articles obtained by injection-molding the composition are available as components having reduced anisotropies of mechanical characteristics and mold shrinkage factor.
