Abstract : The development of a fabric that would be protective against high-intensity thermal energy was approached using three criteria, the first being that the majority of the fiber in the fabric be a textile material. After evaluating various fibers, Nomex was determined to be the primary fiber for this structure. The second parameter examined was that of a known spacing between two layers of fabric studied in various ways. The final concept arrived at was a two-layer fabric that was intimately tied together at 3/8 inch intervals. The third effort was directed toward finding a fibrous material that would absorb or distribute the thermal energy within the fabric itself. Of the many metallic and inorganic materials evaluated, a slit aluminum foil/Mylar film yarn was considered to be the optimum structure for its weight and bulk. The fabric developed from this fiber and structure evaluation was a 7.3 oz/sq yd two-layer Nomex fabric tied together at intervals, either with or without a slit aluminum scrim between the two layers.
