PRODUCTION OF LAMINATED SHEET

摘要

PURPOSE:To produce a laminated sheet reduced in warpage and distortion. CONSTITUTION:A vinylester resin impregnated long fabric having warp yarns whose twist direction is composed of a mutually reverse combination is arranged on the upper and rear surfaces of a vinylester resin impregnated long nonwoven fabric and a long metal foil is further arranged to the outermost layers thereof to form each of long laminates. The long laminates thus formed are continuously laminated and molded to be cut into a required dimension to be reheated to a glass transition point or higher before quenched.
