FIBER-REINFORCED POLYESTER RESIN MOLDING MATERIAL, ITS PRODUCTION, AND ITS MOLDED PRODUCT

摘要

PROBLEM TO BE SOLVED: To provide a fiber-reinforced polyester resin material which can be easily subjected to a molding process, such as extrusion molding, blow molding, or an expansion molding, suited for a fiber-reinforced polyester resin molding material and can be desirably used in also injection molding to give a molding excellent in mechanical properties, to provide a method for producing the same, and to provide a molded product of the same. SOLUTION: There are provided a fiber-reinforced polyester resin molding material satisfying the relationship:λ/η= 15-40 (whereinλis the elongation viscosity andηis the shear viscosity as measured with a capillary rheometer at a shear rate of 100-1) and a fiber-reinforced polyester resin molding material having an elongation viscosity (λ) of 10-50 kPa s as measured with a capillary rheometer at 280 deg.C and a shear rate of 100-1.
