Repair apparatus and method for composite panels having a conductive layer

摘要

A repair apparatus for an electrically conductive layer of a composite structure includes a dielectric layer, having a perimeter, secured to the structure, and a conductive layer, secured over the dielectric layer and to the structure around an entirety of the perimeter of the dielectric layer, the conductive layer being treated along a perimeter region thereof to improve a conductive path between the conductive layer and the structure.

主权项

1. A method for temporarily repairing a conductive composite panel having a damaged area near a metal fastener, comprising:
preparing a surface of the panel in the region of the damaged area and the fastener; affixing a dielectric material to the panel with an adhesive, the dielectric material covering the damaged area and the fastener; providing an adhesive on a conductive patch; scoring the adhesive along a perimeter region of the adhesive on the conductive patch; affixing the conductive patch to the dielectric material and the panel with the adhesive, the conductive patch entirely covering the dielectric material and defining a perimeter region in contact with the panel; and wherein scoring the adhesive increases an electrical conductivity between the panel and the conductive patch.
