Abstract

An EOD suit is designed to shield personnel from the effects of explosions, such as those caused by improvised explosive devices. Beside ballistic protection, it must ensure thermal comfort of the operator. Here we demonstrate the efficiency of a subvestimentar cooling system based on 1 teradecanol as phase change material macro encapsulated in aluminized polypropylene. DSC studies prove the thermal stability of the system during 10 heating/cooling cycles, maintaining the temperature in the range 23.83 oC 45.77 oC with a mean enthalpy of transformation 224.78 229.27 J/g and mean thermal conductivity measured with the planar hot disk method 0.30165 W/mK.
