PURPOSE:To provide a method for manufacturing a fiber reinforced thermoplastic resin molded body having a high strength and excellent appearance by using fiber composite sheets wherein fibers have already been jointed by a thermoplastic resin. CONSTITUTION:Two fiber composite sheets 8 wherein fibers have been jointed by a thermoplastic resin of 10-80wt.% are superposed and arranged in a cavity 11 of a lower mold 10 of a compression mold 9 whose temperature is adjusted. An outlet 12 of a movable extruder is moved on the fiber composite sheets 8, while a melted homopolypropylene is supplied from a nozzle 13. An upper mold 15 is made to descend and opened at about 100kg/cm<2>, cooled to a product temperature of about 70 deg.C with pressure, and a molded body 16 on a plane plate is taken out. Thus, a product having a high strength can be obtained by melting a fiber jointing thermoplastic resin and a supplying thermoplastic resin. As a thermoplastic resin layer is formed on the surface of the molded body, a product having excellent appearance can be obtained. |
