Abstract: Provided is a thermoplastic resin composition including 30 to 50 wt % of a polybutylene terephthalate resin (A); 8 to 20 wt % of a polyethylene terephthalate resin (B); 3 to 15 wt % of an acrylate-aromatic vinyl compound-vinyl cyanide compound graft copolymer (C); 3 to 15 wt % of an aromatic vinyl compound-vinyl cyanide compound copolymer (D); 25 to 40 wt % of glass fiber (E); 0.15 to 1 wt % of a carbodiimide-based compound (F); 0.5 to 1.5 wt % of an epoxy compound (G); and 0.25 to 1.2 wt % of a hindered amine-based light stabilizer (H), a method of preparing the thermoplastic resin composition, and a molded article including the composition.
The thermoplastic resin composition has excellent impact strength, tensile and flexural strength, and flexural modulus, and excellent heat resistance; has excellent flexural strength retention rate after the Air-HAST test; and satisfies product reliability required by automotive exterior materials and materials for electric/electronic parts.

Abstract: The present disclosure relates to a thermoplastic resin composition and a molded article manufactured using the same. The present disclosure has an effect of providing a thermoplastic resin composition having tensile strength and flexural modulus equal or superior to those of a conventional polyester composite material; having greatly improved impact strength, flexural strength, and heat deflection temperature under high load; and thus being suitable for lightweight automotive parts requiring high rigidity, and a molded article manufactured using the thermoplastic resin composition.
