Abstract
In an attempt to study the oxidation phenomena of the thermal protective materials, test on carbon fiber reinforced carbon (C/C) composite have been conducted in plasma arc facility under the similarly MARS and other planet entry conditions. An arc heated wind tunnel used for thermal protective testing of ablation materials for capsule, probe and space vehicle. The study of attempts of ablation phenomena related the plasma characteristics to the thermally decomposed gas, the chemical composition and material structure after an arc heating test. Sample heating test during virgin C/C and C/C composite penetrated with dimethyl silicone oil target in a CO2 arcjet flow is experimentally investigated on measurements of emission spectra in shock layer and internal temperature distribution in the ablation materials.
