Abstract
Impregnated veil and compression molding process of reinforcing fiber pre-impregnated continuous and discontinuous thermoset and thermoplastic materials. Veils are incorporated within the process, filming or laminating stages of the pre-pregging, either hotmelt or solvent based processes, in a variety of chosen resins. The veils help to improve visual part quality, reduce fiber splitting, and provide an isolating material in applications where incompatible materials must exist.
