GLASS FIBER-REINFORCED RESIN MOLDED ARTICLE

WIPO Patent Application WO/2022/254914

A1

The present invention provides a glass fiber-reinforced resin molded article which is reduced in anisotropy of shrinkage, while being remarkably reduced in the occurrence of a warp.　A glass fiber-reinforced resin molded article which is configured such that: the glass fibers have a flat cross-sectional shape that has a ratio of length to breadth (length/breadth) within the range from 5.0 to 10.0; the thermoplastic resin is a polyaryl ether ketone; the number average fiber length L of the glass fibers having a length of 25 μm or more in the glass fiber-reinforced resin molded article is within the range from 50 μm to 300 μm; the proportion PS of the glass fibers having a length within the range from 25 μm to 100 μm in the glass fiber-reinforced resin molded article is within the range from 20.0% to 60.0%; the proportion PL of the glass fibers having a length of 500 μm or more in the glass fiber-reinforced resin molded article is within the range from 1.0% to 15.0%; and the proportions PS and PL satisfy formula (1).　(1): 39.5 ≤ L × PS 2/(1000 × PL) ≤ 82.4
