| Popis: | Carbon fiber reinforced polymers (CFRPs) are increasingly used in the latest generations of aircraft, but their low electrical conductivity is a concern for lightning strike protection. During the past few years, development of lightning strike protection solutions for CFRP has attracted increasing interest, and cold spray is one coating approach to achieving this. In this work, pure tin coatings and tin–copper composite coatings were cold sprayed on CFRP as possible lightning strike protection materials. The coatings were subjected to various mechanical and electrical characterizations. The effect of annealing on electrical conductivity was also examined. Furthermore, continuous current injection tests, which duplicated component C of a lightning waveform, were performed on the coatings. The results showed that the cold-sprayed coatings can provide effective protection to the CFRP underneath when subjected to currents up to 200 A with 1-s duration. |
