Abstract

Systems and methods are provided for fabricating composite parts. One embodiment is a method that includes heating a female die having a receptacle and a complementary male die, heating an extruder above a melting point of a thermoplastic within chopped prepreg fiber, in order to melt chopped prepreg fiber disposed within the extruder, extruding the chopped prepreg fiber from the extruder into the receptacle of the female die while the chopped prepreg fiber remains molten, pressing the male die into the female die, causing the molten chopped prepreg fiber to fully enter receptacle, and cooling the chopped prepreg fiber in the receptacle of the female die to form a composite part.
