ABSTRACT:
A polymeric ablative liner material based on carbon and silicone polymers and particulate fillers which is tailored to control the endothermic chemical reaction and thereby optimize the ablation process to provide maximum cooling and remaining char. The ablative liner material includes hydrocarbon polymers and has a molar ratio of carbon to silicon within the range of about 2 to 8. This composition optimizes the generation of gases for transpirational cooling, the cooling resulting from the endothermic chemical reaction, and the amount of stable char that remains after the ablation process is completed.
