MANUFACTURE OF MOLDED SHEET MATERIAL, FIBER REINFORCED MOLDED SHEET MATERIAL MANUFACTURED THEREBY, AND FRONT CORE OF SAFETY SHOES USING THE MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a fiber reinforced molded sheet material which does not lower moldability and has high strength. SOLUTION: A molded sheet material in which pellets prepared by cutting a rod in which a bundle of reinforcing monofilaments is impregnated with a resin, or chips prepared by cutting a plate in which a cloth woven with the reinforcing fibers is impregnated with the resin are collected and heat-pressed. Since the content of the reinforcing fibers is large in the sheet material, high strength is obtained. Since the resin of smaller molecular weight is used, the fluidity is not lowered. Therefore, a product of high strength is obtained.
