Moldable composite

Abstract

The formation of a composite formed by spreading a liquid thermosetting resin over a continuously moving plastic film or sheet. Chopped fiber is added and a fabric or veil, such as dacron polyester cloth, is continuously laid over the top to form a reinforced composite. This continuously produced thermosetting resin composite is rolled into a coil. After a maturation period, the plastic film or sheet may be removed from the SMC composite and sections of appropriate size and weight are cut from the coil and placed over the die of a compression molding machine, veil side down, up or both. The material is then compression molded at a pressure of 500-3000 p.s.i. (35 to 210 kg. per sq. cm.) and a temperature of 100.degree.-165.degree. C., and cured into an article. The fabric used has a grab break strength of at least 10 lbs. (4.5 kg.) in both longitudinal and transverse directions, and a tensile elongation of at least 10%, and is sufficiently permeable to permit liquid resin to pass therethrough during compression molding.
