A method is disclosed for creating a strong point for the attachment of carbon composites to metallic bodies that is suitable at high temperatures (1600.degree. F.) as well as ambient temperatures. A pocket of suitable dimensions and depth is molded into the carbon composite structure on both sides at an edge, with the edge relieved and rounded. A hole for a fastening member is molded or drilled in the approximate center of the pocket. After preparation of the surface the pocket, through hole, and relieved edge are nickel-plated to produce a rigid strong point. A doubler can be brazed to the nickel plate to strengthen the bond. The disclosed method can be used for attaching any type of electrically conductive composite material to a metallic structure.
