Document Type and Number:
WIPO Patent Application WO/2023/074305
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a fiber-reinforced thermoplastic resin molded article that has, as a molded article, excellent mechanical properties, in particular flexural modulus, and appearance qualities, in particular warpage prevention effect. The fiber-reinforced thermoplastic resin molded article contains a reinforcing fiber (A) having a weight average fiber length of 0.4-1.5 mm inclusive and a heat conductivity in the fiber axial direction of 5 W/mK or higher, a polyamide resin (B) a matrix resin of which has a melting point of 210°C or lower, and a modifier (C), wherein, relative to 100 parts by mass of the aforesaid (A) to (C): the content of the reinforcing fiber (A) is 10-30 parts by mass inclusive; the content of the polyamide resin (B) is 60-89 pars by mass inclusive; and the content of the modifier (C) is 1-10 parts by mass inclusive.
