Abstract
A conductive fastening system, a fastened assembly, and a method of fastening an assembly composed of layers of carbon fiber reinforced plastic (“CFRP”) and/or metallic material includes fasteners with an electrically conductive coating and electrically conductive gap filler materials between the fasteners and sidewalls of holes formed through the layers of the assembly. The sidewalls of the holes are coated with the electrically conductive gap filler material by abrading, injection or spraying. The fasteners with the electrically conductive coating are inserted through the holes. The conductive coating on the fasteners and electrically conductive gap filler material work together to enhance electrical conductivity between the fastener and assembly. The conductive coating also acts as a lubricant to reduce the amount of force required to insert the fastener into the hole thereby reducing damage to the assembly.
