ABSTRACT:
An integral lightning protection system and method for its use with an aircraft graphite epoxy structure. If a repair is to be made to an aircraft composite structure, the hole to be repaired is first cleared of broken composite material and replaced with a bonded adhesive patch. Over the patch and conformal to the surface of the aircraft composite structure, a dielectric layer is placed, and over the dielectric layer, at least one metal-plated graphite fiber fabric ply is placed. Where fasteners are inserted through an aircraft composite panel, the heads of the fasteners are left flush with the outer surface of the composite material, and the composite material and fastener heads are adhesively covered by a dielectric cover. Thereafter, at least one metal-plated graphite fiber fabric ply is placed over the dielectric layer. Subsequently, either structure may be given a primer and paint coating.
