Abstract:In this paper,conductive layer was made on the surface of composite ply,such as flame spraying aluminum coating,expanded aluminum foil,aluminum foil.The preparation process,the analysis of electrical resistance as well as the applicability on the large airplane were investigated and analysed in detail.The results show that,the above three lightning protection layer significantly improved the conductivity of the composite materials and has the very good applicability.
Keywords:Lightning strike protective layer  Ablation  Co-curing  Conductivity  Applicability
