The present disclosure is directed to an exterior surface protective layer for protecting a composite structure from environmental conditions including: at least one curable film; such as at least two curable films, and an electrically conductive material, wherein the electrically conductive material comprises a wire-free electrically conductive material, and/or an electrically conductive polymer weave, wherein the at least one curable film includes at least one of polyurethane, polyimide, polyester or epoxy upon curing, and wherein a weight of the exterior surface protective layer ranges from about 0.02 pounds per square foot to about 0.1 pounds per square foot. An exterior surface protected composite structure and methods of forming an exterior surface protected composite structure are also provided. Il est décrit une couche protectrice de surface extérieure pour la protection dune structure composite contre des conditions ambiantes, y compris au moins un film thermodurcissable, ainsi quun matériau électroconducteur, le matériau électroconducteur comprenant un matériau électroconducteur sans fil, et/ou une armure de polymères électroconductrice, tout film thermodurcissable comprenant polyuréthanne, polyimide, polyester et/ou époxy après le durcissement, et un poids de la couche protectrice de surface extérieure variant denviron 0,10 kilogramme par mètre carré (environ 0,02 livre par pied carré) à environ 0,49 kilogramme par mètre carré (environ 0,10 livre par pied carré). Il est également décrit une structure composite de surface extérieure protégée, ainsi que sa méthode de formation.
