▎ 摘  要

NOVELTY - Manufacturing composite material pellets comprises (a) preparing a metal-coated carbon fiber (MCF); (b) passing the bundle of the metal-coated carbon fibers through a thermoplastic resin impregnation tank to produce a metal-coated carbon fiber impregnated with a thermoplastic resin; (c) preparing a long fiber reinforced thermoplastic (LFT) by curing the thermoplastic resin of the metal-coated carbon fiber impregnated with the thermoplastic resin; and (d) cutting the long fiber-reinforced thermoplastic plastic to a predetermined length to form pellets. USE - The composite material pellets is useful for electromagnetic wave shielding product comprising molded body manufactured by injecting electromagnetic wave shielding composite material pellet (claimed). ADVANTAGE - The composite material pellet has excellent mechanical properties with high electromagnetic wave shielding performance even when the content of metal-coated carbon fiber is increased to more than 10 wt.%.
