The present invention relates to a polycyclohexylene dimethylene terephthalate-based composite material composition. The invention includes: a polycyclohexylene dimethylene terephthalate resin; 0.1 to 55 parts by weight of a plate-like glass fiber based on 100 parts by weight of the polycyclohexylene dimethylene terephthalate resin; and 0.1 to 50 parts by weight of TiO_2 based on 100 parts by weight of the polycyclohexylene dimethylene terephthalate resin, wherein the plate-like glass fiber has 2 to 4 of W/D, and the TiO_2 is coated with an aluminum oxide and an organosiloxane. The polycyclohexylene dimethylene terephthalate-based composite material composition of the present invention is capable of an injection molding, has a low moisture absorption rate, shows excellent heat resistance, discoloration resistance by heat, and flame resistance, and has a high degree of whiteness and therefore, can be used in light-emitting diode (LED) reflectors. |
