GLASS FIBER-REINFORCED POLYESTER RESIN COMPOSITION AND MOLDED PRODUCT USING THE SAME

摘要

PURPOSE: A glass fiber-reinforced polyester resin composition and a molded product thereof are provided to secure the high tensile strength and flexural strength of the product after inserting the composition. CONSTITUTION: A glass fiber-reinforced polyester resin composition contains 30~80wt% of polyester resin, 5~30wt% of vinyl copolymer, and 10~50wt% of glass fiber including the aspect ratio at the cross section over 1.5. The polyester resin is an aromatic polyester resin selected from the group consisting of a polyethylene terephthalate resin, a polytrimethylene terephthalate resin, a polybutylene terephthalate resin, a polycyclohexane dimethylene terephthalate resin, a polyhexamethylene terephthalate resin, and their combination.
