High Performance Ablative Rubber Nanocomposite Heat Shield Based on NBR

Rubbery ablative materials are widely used in heat shields. Thermal insulation by ablation is achieved through the degradation of material itself and the formation of a refractorychar on the material surface, thereby hindering the transfer of heat into the interior of material. Rubber basednanocomposites have some excellent properties due to combination of thermal, ablation and improved mechanical properties which are important to enhance the material performance especially for rocket motor chamber in aerospace application [1-3].
