COMPOSITE BODY OF METAL ALLOY AND CARBON FIBER REINFORCED PLASTIC AND ELECTRO-CORROSION INHIBITION METHOD THEREOF

摘要

PROBLEM TO BE SOLVED: To satisfy a demand for solving the following problems that; corrosion is generated on an aluminum alloy side of a composite body of an aluminum alloy and CFRP pre-preg by a battery reaction when the composite body is wet by rain or dew, and thus measures for such a phenomenon as above have already been demanded in an air plane technology field wherein CFRP is widely adopted and also demanded in future in an automobile technology field.;SOLUTION: Metal alloys having specific surface shapes and specific surface properties can strongly be adhered to each other by an epoxy adhesive agent, and also the metal alloy can strongly be adhered to CFRP by an epoxy adhesive agent. By using this technology, an aluminum alloy, CFRP and a copper alloy are compositely adhered to one another by an epoxy adhesive agent, a conductor is drawn out of an aluminum alloy part and a copper alloy part, then, a DC power supply is connected to the conductor, and a prescribed voltage is applied thereto, thus preventing a battery reaction.;COPYRIGHT: (C)2010,JPO&INPIT
