A method of making a prepreg composite sheet comprising contoured charges includes receiving, at a computer-numerically-controlled (CNC) device, a mapping, corresponding to shapes of layers of a laminated precursor article to be formed from the contoured charges. The method also includes forming, by the CNC device using the mapping, precursor outline regions in a resin film layer, wherein the precursor outline regions have the shapes of the layers of the laminated precursor article, and wherein the resin film layer has a viscosity. The method further includes impregnating a fiber reinforcement having fibers with the resin film layer to form non-impregnated outline regions that define the contoured charges in the prepreg composite sheet, wherein the non-impregnated outline regions correspond to the precursor outline regions in the resin film layer.
