Abstract: Provided is a protection film including a plurality of layers, including a first carrier layer having a plurality of electrically conductive fibers; a metal layer; and a second carrier layer having a plurality of electrically conductive fibers. Each of the first and second carrier layers has a void volume at least partially filled with a hardenable composition. Also provided is a protection film including a first metal layer, a carrier layer, and a second metal layer, in which the carrier layer is at least partially filled with a hardenable composition. These films can provide lightning strike protection with suitable tensile, rigidity and tack properties for automatic tape layup and automatic fiber placement applications.

Abstract: A lightning protective seal cap comprising a seal cap that defines an interior, and a quantity of an uncured sealant that is curable by the application of actinic radiation so as to bind the seal cap to a fastener. The interior of the seal cap contains the quantity of uncured sealant, the seal cap is positionable over the fastener such that at least a portion of the fastener resides in the interior of the seal cap, and when the seal cap is in position over the fastener, the sealant containing seal cap prevents electrical arcing to the fastener from a lightning strike.
