RELEASE SHEET FOR MOLDING PREPREG MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a release sheet for molding a prepreg material excellent in mechanical strength and preventing the contamination of a mold caused by the oligomer or fretting powder precipitated from the release sheet at the time of thermoforming. SOLUTION: The release sheet for molding the prepreg material is constituted by laminating a polyolefin resin film having heat resistance and releasability, a resin film, and a heat-resistant engineering plastic film having a phenyl group in its skeleton in this order.
