 Abstract:
Carbon fiber reinforced polymers (CFRP) have taken over from aluminum for aircraft structures for lightweight purpose, but this leaves vulnerability for lightning strike. To make polymers lightning strike proof, a conductive media must be either embedded in or coated on the polymers. Cold spray is one approach to achieve this. The aim of this work is to cold spray a metal film with sound mechanical properties and good electrical and thermal conductivity on polymers used in aircraft for lightning strike protection. Copper, aluminum and tin were used as the coating materials, and different gas pressure and preheating temperature combinations were used for the cold spray process. The electrical conductivity of the metal coatings was measured to investigate the lightning strike protection potential of the cold sprayed coatings on CFRP.
