Abstract
The present invention relates to a thermoplastic composite composition comprising (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.
