COMPOSITE MATERIAL IMPROVED IN JUNCTION STRENGTH AND METHOD FOR FORMING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a composite material in which metal is provided on the surface of a resin substrate, and the junction strength between the substrate and the metal is improved by heat-cladding the metal on the substrate. SOLUTION: The composite material has the metal on the surface of the resin substrate which is obtained by subjecting the surface of the substrate to ion exchange group introduction treatment, treats the surface of the substrate with a solution containing metal ions to introduce the metal ions, and reduces the metal ions. The metal is heat-clad on the substrate. The junction strength between the metal and the substrate of the composite material is higher than that of a composite material obtained by electroless plating. Since a heat- cladding method is available for forming the composite material, the composite material can be produced simply.
