Abstract
PURPOSE: To prepare a glass fiber reinforced resin composition having excellent mechanical strength, heat resistance, and heat distortion resistance, by compounding polyethylene terephthalate with glass fiber having a length to diameter ratio in a specific range.
CONSTITUTION: A polyethylene terephthalate (PET) having an intrinsic viscosity of 0.45W1 or a mixture of said PET and a rubbery polymer and/or an epoxy compound is compounded with 20W150pts.wt., based on 100pts. of the PET, of glass fibers wherein the weight-average ratio of the length (L) to the diameter (D) is 5W30, preferably 5W20, and the content of the fibers having L/D of 5W10 is ≥50wt%. Addition of 2W20pts. of a rubbery polymer, based on 100pts. of the sum of PET and glass fiber, remarkably improves the falling ball impact strength, and addition of 0.05W3pts. of an epoxy compound remarkably improves the thermal stability in melt molding.
