PREPARATION METHOD OF FIBER REINFORCED COMPOSITE MATERIAL AND FIBER REINFORCED COMPOSITE MATERIAL PREPARED THEREBY

PURPOSE: A manufacturing method of fiber reinforced composite materials and a fiber reinforced composite material manufactured by using the same are provided to reduce manufacturing costs and simplify manufacturing processes. CONSTITUTION: A manufacturing method of fiber reinforced composite materials comprises the following steps: cutting a thermoplastic resin film to fit into a mold(10); laminating the thermoplastic resin films(70,70') between fiber textiles(60,60',60") by turns; and autoclaving and press molding the laminated mold materials. In the molding step, the thermoplastic resins are impregnated between the fiber textiles by temperature and pressure. The fiber reinforced material is one or more selected from a natural fiber, a synthetic fiber, carbon fiber, ceramic fiber, glass fiber, metal fiber and metallized fiber. In the molding step, the pressurization condition is 1-5kgf/cm^2 and a temperature is 100-200 deg. Celsius.
