ABSTRACT:
The present invention provides composite material compositions using waste synthetic fiber released from fiber-related factories or general households. In an embodiment of the present invention, a thermoplastic synthetic resin may be incorporated with plasticizer(s), lubricant(s), and other additive(s), the mixture being molten and then kneaded with waste synthetic fiber which had been fibrillated into filaments, whereby said waste synthetic fiber is impregnated with the molten resin liquid to form a composite material composition. The present invention can thus provide inexpensive composite material compositions having excellent mechanical properties by making use of waste synthetic fiber which has been junked as waste so far, and lessening the rate of use of synthetic resins.
