High temperature thermal chemical ablative calculation for carbon compositematerials by minimization of energy function

The high temperature thermal chemical ablative result s for carbon composite materials were calculated byminimization of the energy function. The experiment s of the high temperature thermal chemical ablation with archeater and plasma torch were carried out . The spect rum diagnoses of gaseous ablative result s for carbon compositematerials were made . The gaseous ablative result s of spect rum diagnoses are consistent with those of calculation byminimization of the energy function. It confirmed the validity of the thermal chemical ablative calculation by minimization of the energy function for carbon composite materials further. The method calculated the thermal chemicalgaseous ablative results not only for carbon composite materials , but also for complex hybrid carbon composite materials.
