HIGH-RIGIDITY AND HIGH-HEAT RESISTANCE THERMOPLASTIC COMPOSITE MATERIAL COMPOSITION AND MOLDED PRODUCT MANUFACTURED THEREFROM

WIPO Patent Application WO/2021/060882

A1

The present invention relates to a thermoplastic composite material composition and a molded product manufactured therefrom and, more specifically, to a high-rigidity and high-heat resistance thermoplastic composite material composition and a molded product manufactured therefrom. The thermoplastic composite material composition comprises: (a) a first polymer resin containing a polyphenylene sulfide polymer having a melt index (ASTM D-1238, 235°C) of 100-150 g/10 min; (b) a second polymer resin containing a polyphenylene sulfide polymer having a melt index (ASTM D-1238, 235°C) of 250-850 g/10 min and an amorphous monomer having aliphatic cyclobutanediol; (c) carbon fibers surface-treated with a polyimide; (d) a fatty acid compound; and (e) a heat-resistant additive. The thermoplastic composite material composition according to the present invention uses a polymer resin containing an amorphous monomer having aliphatic cyclobutanediol, and thus can increase the compatibility of carbon fibers and a thermoplastic resin, leading to an improvement in impregnation properties, so that the thermoplastic composite material composition can be used to manufacture high-rigidity and high-heat resistance aeronautical interior and structural moldings.
