FIBER REINFORCED THEREMOPLASTIC RESIN STRUCTURE AND PRODUCTION THEREOF

摘要

PURPOSE:To efficiently and economically produce a fiber reinforced thermoplastic resin structure having high mechanical strength reinforced by a long fiber and markedly improved in the dispersibility of a reinforcing fiber. CONSTITUTION:The continuous reinforcing fiber bundle taken out of a reinforcing fiber bundle aggregate is impregnated with a molten thermoplastic resin while pulled to produce a fiber reinforced thermoplastic resin structure containing substantially parallelly arranged reinforcing fibers in an amount of 5-800% by wt. of the whole of the structure. In this method, the reinforcing fiber bundle to be used is obtained by forming a fiber bundle composed of fibers subjected to sizing treatment into a cylindrical wound body and drying the same so as not to substantially generate the evaporation from the upper and lower side surface parts of the wound body.
