FILM FOR PRODUCTION OF COMPOSITE MATERIAL ARTEFACTS, PRODUCTION METHOD OF SAID FILM AND PRODUCTION METHOD OF COMPOSITE MATERIAL ARTEFACTS USING SAID FILM

摘要

A resin constraint film (1) to be used in production of composite material artefacts (2); the constraint film (1) being formed by a supporting film (6) made of biaxially oriented polypropylene, by an intermediate layer (7) of release chemical product that coats the front face (6a) of the supporting film (6) intended to come into contact with the semi-finished product (2') which will give rise to the composite material artefact (2), and by a surface layer (8) of metal coating material applied onto the intermediate layer (7) via vacuum vaporisation deposition.
