Abstract

Carbon fiber reinforced plastic (“CFRP”) composite layups and processes for manufacturing CFRP composite layups that integrate z-conductivity features directly into CFRP composite layups during the manufacturing processes for lightning protection, more particularly, inherent edge glow protection from lightning direct effects, and electrical current flow path control. CFRP composite layups are configured during the manufacturing processes to provide inter-ply electrical connections between composite plies of the CFRP composite layups, therefore avoiding the need for add-on protection features that result in significant cost and weight penalties.
