Abstract
A lightning protection repair system for graphite epoxy structures. An aircraft graphite epoxy structure is repaired by fastening a repair plate over the hole to be covered, followed by a dielectric sheet covering the outer surface of the metal repair plate. An electrically conducting lightning diversion sheet, conforming to the outer surface of the repair plate, is fastened to the repair plate through the dielectric sheet. The edges of the lightning diversion sheet are bent toward the outer surface of the aircraft graphite epoxy structure to be adjacent or touching its outer surface. Sealing compounds can be used around the repair plate to prevent moisture intrusion, and the repair can be faired into the aircraft graphite epoxy structure by means of a fairing compound.
