摘要： Provided is a continuous fiber reinforced composite including a thermoplastic resin, fibers, and metal wires. Also provided is a method of preparing a continuous fiber reinforced composite, and the method includes impregnating fibers provided from at least one fiber creel or metal wires provided from at least one metal wire creel in a thermoplastic resin to form a melt; molding a shape of the melt by using a mold and curing the resultant by heating in a heating tube to form a primary cured product, as a primary molding process; re-molding the primary cured product by using the mold again and curing the resultant by heating in the heating tube to form a secondary cured product, as a secondary molding process; and cooling, pultruding, and cutting the secondary cured product to perform finishing of the product.

摘要： Disclosed herein are a fiber-reinforced plastic composition containing a thermoplastic resin, a reactive rubber (reactor-made thermoplastic poly olefin, RTPO), and a glass fiber; and a fiber-reinforced composite prepared from the fiber-reinforced plastic composition. Furthermore, provided is a method for preparing a fiber-reinforced composite, the method comprising the steps of: preparing a thermoplastic resin composition by feeding a thermoplastic resin and a reactive rubber into a first extruder, followed by melting and kneading; preparing a fiber-reinforced plastic composition by feeding the prepared thermoplastic resin composition and a fiber into a second extruder, followed by kneading; and molding the prepared fiber-reinforced plastic composition to prepare a fiber-reinforced composite.
