METAL-FOILED LAMINATED PLATE

摘要

PURPOSE:To improve bendability with exhibition of characteristics of both resin and substrate, by combining a specific resin and a specific substrate into a metal-foiled laminated plate. CONSTITUTION:A sheet of substrate comprising meta-type aramid fibers and polyethylene terephthalate fibers is used. This substrate is integrated with metal foils on one side or both sides of a layer impregnated with expoxy resin containing an acrylonitrile/butadierne copolymer having carboxyl group at the terminal. The sheet of substrate may be a composition of meta-type aramid fibers and glass fibers or a composition of glass fibers and polyethylene telephthalate fibers. These sheets of substrate may be woven fabrics or non- woven fabrics. In this manner, excellent bendability can be imparted to resin by making expoxy resin contain an acrylonitrile/butadiene copolymer having carboxyl group in the terminal.
