1. An exterior surface protective layer for protecting a composite structure from environmental conditions, said exterior surface protective layer comprising:
at least first and second curable film layers; and
a wire-free electrically conductive layer,
wherein each of the at least first and second curable film layers independently comprises at least one of polyurethane, polyimide, and polyester upon curing,
wherein the wire-free electrically conductive layer is selected from the group consisting of a nanomaterial and an electrically conductive polymer weave comprising non-metallic conductive fibers and/or metallic fibers, wherein the non-metallic conductive fibers and/or the metallic fibers of the electrically conductive polymer weave are not composite materials prepared by coating non-conductive filaments, 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,
wherein the wire-free electrically conductive layer is disposed between the first and second curable film layers,
wherein electrically conductive materials are not incorporated into the first and second curable film layers,
wherein the first and second curable film layers do not comprise epoxy, and
wherein the first and second curable film layers each independently have a thickness ranging from 0.05 millimeters to 0.33 millimeters.
