PURPOSE:To mold a thin resin film excellent in brittleness by placing a fiber fabric on a crystalline thermoplastic resin film and placing a second crystalline thermoplastic resin film on the fabric and pressing the whole under heating in an autoclave to quench the same at a cooling speed of 10 deg.C/sec or higher. CONSTITUTION:Glass cloth 12 with a thickness of 50mum is placed on a first resin film 11a composed of a polyphenylene sulfide resin with a thickness of 25mum and m.p. of 281 deg.C and a second resin film 11b with a thickness of 25mum is placed on the glass cloth 12. The whole is introduced into an autoclave to be heated and pressed at 300 deg.C or higher under pressure of 5kg/cm<2> to form an integrated fiber fabric composite polyphenylene sulfide resin film 13 with a thickness of 75mum. Since the whole is uniformly heated and pressed under vacuum within the autoclave, the resin is sufficiently infiltrated in the fabric. The film taken out of the autoclave is suddenly cooled at a cooling speed of 10 deg.C/sec or higher and the crystal growth of the resin is suppressed and brittleness is improved. |
