Abstract
A molding process that uses a textured interfacial layer to isolate the surface of a mold from the surface of a composite article produced with the mold. A solution is deposited on the mold surface to form the interfacial layer, whose surface opposite the mold is textured. The texture of the interfacial layer is then transferred to the surface of the composite article produced with the mold. After demolding, the interfacial 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.
