In recent years, composite use in air and space craft has expanded dramatically. Composite materials present unique challenge for vehicle survival in lightning and related electromagnetic environments. The current approach is to incorporate expended metal foils onto the outer layer of vehicles which protrude at the edges to facilitate bonding. These metal foils add significant weight and processing complexity. A number of alternative materials have been proposed to replace metal foils. Further, addition of thermal protection materials or other coatings such as paint can cause metal foil-treated composites to fail in the lightning environment. In order to design lightning hardened vehicles with metal foils or to evaluate materials to replace the foils, advanced simulation technologies are required. This submission describes our measurement and simulation approach that is useful to advance the electromagnetic compatibility of composite materials.
