<p>PURPOSE:To obtain a laminated member which is superior in external appearance, electric insulation resistance and drill processing properties, by quenching the laminated member containing thermoplastic resin down to the vicinity of a room temperature after the same has been annealed down to a specific temperature after the same has been molded through heating. CONSTITUTION:As thermoplastic resin, polyamide resin or polyester resin or polyurethane resin is used and further as required thermosetting resin such as phenolic resin or epoxy resin can be used. As the thermoplastic resin, it is used in a form of a resin sheet or a resin film or a resin-impregnated base. As for the base, woven fabric or nonwoven fabric or mat or chesecloth or paper composed of an inorganic fiber or an organic fiber or a combined base of the foregoing can be used. As generation of internal strain can be prevented when the above things are quenched down to the vicinity of a room temperature after they have been annealed down to a temperature range of the fusion point - fusion point -50 deg.C of the applied thermoplastic resin by natural cooling after they have been laminated, heated and molded, an external appearance, electric insulation resistance and drill processing properties can be improved.</p> |
