Abstract
A system for fabricating a composite article includes a pre-impregnation station for forming a prepreg comprising a reinforcement impregnated with a resin. The prepreg is provided to a blanking station where a blank is cut from the partially cured prepreg and arranged onto a preforming mold. The blank is then transferred to a forming station, and is formed into the composite article using a compression mold. The pre-impregnation station, the blanking station and the forming station are co-located. During forming of the blank into the composite article using the compression mold, additional prepreg is formed in the pre-impregnation station and passes to the blanking station so as to form a next blank for being formed into a next composite article during a subsequent molding cycle. Optionally, the prepreg is partially cured prior to being cut in the blanking station.
