Abstract
Official abstract text for this publication.
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 (η) 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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A thermoplastic resin composition comprising 30 to 90 parts by weight of a thermoplastic resin and 70 to 10 parts by weight of glass fibers having a weight average glass fibers length of 1.8 mm to 30 mm, wherein the glass fiber content (W) of the thermoplastic resin composition and the melt viscosity (η) of the thermoplastic resin composition at a molding temperature, as determined at a shear rate of 1,000 sec −1 , satisfy equation 1: η(Pa·s)≧2.5…
