摘要： Provided is a molded article that has both a low specific gravity and high rigidity and further has suppressed wrinkles and scrapes, and a manufacturing method for the same. Hence, provided is a press-molded article manufacturing method for press-molding a sheet-shaped molding substrate that is disposed in a cavity of a molding die and contains reinforcing fibers randomly dispersed in a matrix resin using a press molding machine provided with a molding die that is a convex molding die provided with a cavity formed between a concave mold for forming an opening of a molded article and a convex mold that matches with the concave, and has at least one surface (B) on which a pressure is loaded in a range of 0% to 70% of a pressure loaded on a surface (A) when the pressure loaded on the surface (A) from the press molding machine is 100% with respect to the surface (A) orthogonal to a direction of pressure applied to the molding die from the press molding machine, the press-molded article manufacturing method comprising: a shaping step (III) of loading a surface pressure of 1 MPa or more as an external pressure from the press molding machine to the surface (A); and a pressure holding step (IV) of setting a pressure loaded as an external pressure from the press molding machine on the molding substrate to 0.1 MPa or less without releasing the molding die after the shaping step (III).

摘要： Systems (300, 900) and methods (200) are provided for fabricating composite parts. One embodiment is a method (200) that includes heating (202) a female die (120, 920) having a receptacle (124, 924) and a complementary male die (110, 910), heating (206) an extruder (320, 800, 950) above a melting point of a thermoplastic within chopped prepreg fiber (652, 860, 956), in order to melt the chopped prepreg fiber (652, 860, 956) disposed within the extruder (320, 800, 950), extruding (208) the chopped prepreg fiber (652, 860, 956) from the extruder (320, 800, 950) into the receptacle (124, 924) of the female die (120, 920) while the chopped prepreg fiber (652, 860, 956) remains molten, pressing (210) the male die (110, 910) into the female die (120, 920), causing the molten chopped prepreg fiber (652, 860, 956) to fully enter the receptacle (124, 924), and cooling (212) the chopped prepreg fiber (652, 860, 956) in the receptacle (124, 924) of the female die (120, 920) to form the composite part.
