SYSTEMS AND METHODS FOR MAKING PREPREG COMPOSITE SHEETS INCLUDING CONTOURED CHARGES

摘要

A system (100) for making a prepreg composite sheet (300) comprising contoured charges (308) comprises first means (102) for forming precursor outline regions (206) in a resin film layer (200). The system (100) also comprises second means (106) for impregnating a fiber reinforcement (220), comprising fibers (222), with the resin film layer (200), comprising the precursor outline regions (206), to form the prepreg composite sheet (300). The prepreg composite sheet (300), as so formed, comprises non-impregnated outline regions (310) that define the contoured charges (308). The non-impregnated outline regions (310) in the prepreg composite sheet (300) correspond to the precursor outline regions (206) in the resin film layer (200). The system (100) further comprises third means (104) for guiding the fiber reinforcement (220) and the resin film layer (200) to the second means (106). The resin film layer (200) comprises the precursor outline regions (206) formed by first means (102).
