Abstract: A multifunctional surfacing material capable of providing lightning strike protection (LSP) and burn-through resistance. In one embodiment, the multifunctional surfacing material is composed of a conductive layer positioned between two resin layers, at least one of which contains one or more fire retardant compounds. In another embodiment, the multifunctional surfacing material is composed of a conductive layer positioned between two resin layers one of which is a thermally-stable layer. The surfacing material is co-curable with a composite substrate, e.g. prepreg or prepreg layup, which contains fiber-reinforced matrix resin.
