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