THERMOPLASTIC ORGANIC FIBER, METHOD FOR PREPARING THE SAME, FIBER COMPOSITE BOARD USING THE SAME AND METHOD FOR PREPARING THE BOARD

摘要

PURPOSE: A thermoplastic organic fiber containing maleic anhydride, polypropylene is provided to ensure low wetting property and to overcome limit of strength of adhesion power. CONSTITUTION: A method for fabricating a thermoplastic organic fiber used as a base material of fiber composite board comprises: a step of copolymerizing maleic anhydride with polypropylene to prepare copolymer resin; and a step of preparing the thermoplastic organic fiber using copolymer resin. The method further comprises a step of melting the copolymer resin with polypropylene resin to prepare a chip for spinning or a step of mixing the copolymer resin with polypropylene resin to prepare a mixture for spinning. The fiber composite board comprises a base layer(2) containing 30-90 wt% of base material fiber and 10-70 reinforced fiber.
