“Copper-Carbon Nanotube Composites For Lightning Strike Protection”

Abstract
Copper-carbon nanotube composites (Cu-CNT composites) were recently identified as promising materials to withstand large electrical current densities, with their use being considered in a variety of domains where materials progressively hit their current-carrying capacity limits (ampacity). In our work, we aimed to integrate Cu-CNT composites into the lightning strike protection used in aircrafts. The expected outstanding properties of this material result from a synergy between copper, which is among the best electrical and thermal conductors, and CNT, which can have a high ampacity, a low temperature coefficient of resistance, a high conductivity, and a very low density. As a result, pure copper could be replaced in lightning strike protection by a significantly lighter material that has a better resistance to lightning strikes.
