Abstract

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.
