Abstract
PURPOSE: To provide the titled molding material having excellent molding property and shape stability by incorporating glass fibers with a polyester copolymer consisting of polyethylene terephthalate units and polyethylene diphenyl-4,4'-dicarboxylate units.
CONSTITUTION: A base resin uses a polyester copolymer consisting of 10W90mol%, or preferably 20W80mol%, of polyethylene terephthalate units and 90W10mol%, or preferably 80W20mol%, of polyethylene diphenyl-4,4'-dicarboxylate units (to give 100mol% in total). To the polyester copolymer, 5W50wt% of glass fiber is added to provide a glass fiber-reinforced polyester molding material.
EFFECT: Provides a molding material having good molding properties represented by the crystallizing rate and molding cycle, a good shape stability against heat, and excellent mechanical properties.
