Glass-fiber-reinforced resin composition and molded glass-fiber-reinforced resin article

Abstract

Provided is a glass fiber-reinforced resin composition that has excellent strength and an excellent modulus when processed into a glass fiber-reinforced resin molded article and has excellent processability on producing a glass fiber-reinforced resin molded article. In the glass fiber-reinforced resin composition, the content of SiO2S is 48 to 70% by mass and the content of Al2O3 A is 9 to 30% by mass with respect to the total amount of the glass fiber included therein, the glass fiber comprises a flat cross-sectional shape having a minor axis DS of 6.0 to 15.0 μm and a major axis DL of 20.5 to 50.0 μm, the glass fiber content C in the glass fiber-reinforced resin composition is from 65.0 to 85.0% by mass, and S, A, DS, DL, and C satisfy the following formula (1). 2.24 ≤ ( 100 × ( A 2 / S ) × ( C / 100 ) 8 ) / ( DS 3 / 4 × DL 1 / 4 ) ≤ 5.85 ( 1 )
