Patent ID: 11969963

Abstract:
A light-weight, highly-conductive material useful for repairing a lightning protection system in an aircraft. The material includes a nonwoven carbon fiber veil and a metal coating covering the veil. The veil includes a plurality of carbon fibers looped randomly throughout the veil and a binder material that binds the plurality of fibers together. The metal coating covers a portion of a surface of the plurality of bound fibers of the veil, and preferably the entire surface of both the plurality of bound fibers and the binder material, forming a highly-conductive network that follows the shape of the plurality of fibers in the veil. The areal weight is in a range from at least 5 grams per square meter (gsm), up to 12 gsm, and the sheet resistance is in a range from at least 0.5 ohms per square (Ω/□), up to 2Ω/□.
