摘要

A resin constraint film to be used in production of composite material artefacts; the constraint film being formed by a supporting film made of biaxially oriented polypropylene, by an intermediate layer of release chemical product that coats the front face of the supporting film intended to come into contact with the semi-finished product which will give rise to the composite material artefact, and by a surface layer of metal coating material applied onto the intermediate layer via vacuum vaporisation deposition.
