This paper is based on an effort to increase the protection from thermal and flash/flame threats due to explosion. The relatively recent threat of Improvised Explosive Devices, IEDs, the large thermal energy associated with them, as well as the secondary fires has prompted an investigation into whether the personal protective equipment available to the individual soldier provides adequate protection from injury. This is a continuation of a previous paper that investigated the full extent of the threat posed by explosions. The research included a profile of the thermal properties of the threat, typical injuries associated with explosions, as well as several possible means of alleviating the dangers. One means that was suggested was the use of intumescent materials. These are materials that expand when exposed to heat, thus increasing the distance between the threat and the person as well as altering their thermal conductivity to make them more resistant to burn. Using this suggestion, in this paper we seek to determine the feasibility of using these materials in a protective garment. It factors in soldier concerns of durability, comfort, et cetera but focuses mainly on the heat transfer aspects of the material.

By distributing boehmite nanofibers (BNFs) to a resorcinol-formaldehyde (RF) skeletal phase formed by phase separation in an aqueous sol, composite macroporous monoliths have been produced. The nanofiber reinforced monoliths have a skeleton in which BNF is arranged in parallel within the RF structure, and showed high Young's modulus against uniaxial compression for their bulk density. These materials can be expected to be applied to heat/flame protection materials using heat insulating properties and high flame resistance.<br>

There is a need for materials and battings which provide fire resistant properties and are lightweight, washable, and aesthetically accep table. Thermal properties of batts constructed from a new carbonaceous fiber were evaluated to determine its usefulness in military and commercial applica tions for thermal and fire protection. Carbonaceous batts were compared to batts available in commercial and military products on thermal transmittance (conductance and resistance) and thermal protective performance. Results indicated that experimental batts could be constructed to provide insulation comparable to available products. Thermal protective performance tests indicated that the carbonaceous batts provided flame protection superior to current military and commercial products.
