ABSTRACT:
A molding process for a composite article uses a textured film layer to shape the surface of the composite article. The film layer is placed in the mold with the textured film surface exposed and a composite material is placed over the textured film surface. Preferably, the film layer is vacuum-formed onto the mold to take the shape of the mold. As it cures, the composite article takes the shape of the textured film layer to form a textured article surface. After demolding, the film layer adheres to the article as a protective coating, but can be readily removed from the article to expose an underlying textured surface of the article.
