Abstract
(EN)
The present invention provides a glass fiber-reinforced resin molded article which has excellent static and dynamic strength and excellent fluidity in a balanced manner. This glass fiber-reinforced resin molded article is configured such that: the glass fibers contained in this glass fiber-reinforced resin molded article have flattened cross-sectional shapes, each of which has a breadth D1 within the range of 3.0-10.5 μm and a length D2 within the range of 11.0-29.0 μm; the number average fiber length L (μm) of the glass fibers contained in this glass fiber-reinforced resin molded article is within the range of 150-475 μm; the glass fiber content C (wt%) in this glass fiber-reinforced resin molded article is within the range of 40.0-75.0 wt%; and D1, D2, L and C satisfy formula (1). (1): 260.0 ≤ C2 × L/(D1 × D22) ≤ 400.0
(FR)
