Abstract

Aircraft wing composite ribs having electrical grounding paths are described. An example composite rib includes a carbon fiber reinforced plastic (CFRP) panel, a metallic rib post, a metallic fitting, and a metallic grounding member. The metallic rib post is coupled to the CFRP panel and configured to be coupled to a spar of an aircraft wing, the spar being coupled to a current return network (CRN) cable. The metallic fitting is coupled to the CFRP panel and configured to be coupled to a skin panel of the aircraft wing. The metallic grounding member is positioned between the CFRP panel and the metallic fitting. The metallic grounding member provides an electrical grounding path extending from the metallic fitting to the metallic rib post.
