PURPOSE:To obtain the polypropylene film imparting a precise shape and a high strength to a fiber-reinforced composite material, excellent in releasability from the molded fiber-reinforced composite material after thermally cured, and used for processing. CONSTITUTION:This biaxially oriented polypropylene film contains 0.1-3.0wt.% of a polydiorganosiloxane having a polymerization degree of 3000-8000, e.g. polydimethylsiloxane, and has a thickness of 15-50mum and a tensile strength of 18-25kg/mm<2> in the longitudinal direction. |
