This invention is directed to a light weight fire resistant material. The material is constructed of a plurality of oxidized polyacrylonitrile (OPAN) fibers. The fire resistant material having a weight in the range of less than about 9.0 oz/yd, an Arc Thermal Performance Value of greater than about 8.0 and a Thermal Protection Performance of greater than about 13.0.

Fire retardant material and method of making the same

A safe, environmentally-friendly, fluorocarbon-free temperature suppressing composition includes water in combination with a sugar alcohol in solution with the water and having a general formula H(HCHO)H. Sorbitol is a preferred sugar alcohol (n=5) but sugar alcohols having n=3 to 4 or 6 to 11 may be used. The composition provides a heat absorption greater than the water alone and the sugar alcohol alone. Other sugar alcohols having the general formula H(HCOH)HC, where n=10, may also be used. The composition may further include a wetting agent, an emulsifying agent, a viscosity adjusting agent, a preservative or biocide, or a freeze suppression agent. The composition affords levels of protection suited to a variety of applications including possibility of damage from exposure to excessive heat, combustion or explosion such as may be experienced in military combat.
