ABSTRACT:
An improved separator film that can be applied to a layer of composite prepreg material as well as resin based adhesive films to prevent sticking, voids and separator film contamination in formed articles, as well as providing useful handling and storage properties. The separator film of the present invention is designed to either degrade and/or volatilize away so as not to contaminate or leave voids or weak interfaces in the resulting article. The separator film also eliminates the need to inspect the formed article for remaining separator film. In general, the separator film of the present invention is made from a polymer or combination of polymers that can volatilize away or revert into monomers or simpler polymers. This volatilization or degradation into a plurality of reversion products occurs when the separator film is exposed to sufficient heat energy. The reversion products are generally capable of reacting with the resin in the composite prepreg material or alternatively, the adhesive film, such that the separator film actually becomes part of the article being formed.
