Abstract
A method for protecting an underlying structure from directed energy including combining an intumescent material with the underlying structure. The intumescent material forms a barrier to directed energy received on the intumescent material, the barrier suppressing or impeding transmission of the directed energy, and heat generated in the barrier by the directed energy, to the underlying structure.

A fabric comprising:
- fibers forming the fabric, wherein the fibers are woven, non-woven, or embedded in a resin, and wherein the fibers comprise intumescent material.
A composite material comprising:
- fibers forming a fibrous mat, wherein the fibers are woven, non-woven, or embedded in a resin, wherein the fibers comprise intumescent material.
A system comprising:
- an underlying structure comprising one or more of:
- a skin, a structural frame, a fuel tank, a fuel conduit, an aperture for an optical system, or an electronics box;
- a protective layer arranged on the underlying structure;
- the protective layer comprising:
- intumescent material;
- and
- a gap comprising air or thermally insulating material arranged between the underlying structure and the intumescent material, wherein the gap is configured to form a thermal break between the intumescent material and the underlying structure.
