Abstract
Fiber reinforced molded plastic articles, without fiber readout surface defects, are prepared in either resin transfer molding or reinforced reaction injection molding processes, by disposing a surface finishing film across the mold cavity prior to the insertion of the fiber preform and the injection of the curable polymeric precursor materials, thereby producing a finished article wherein the surface finishing film is bonded to the surface of the article filling the areas between those fibers near the surface which would otherwise cause fiber readout.
