Studies on Ablative Performance of Silicone Low-Density Ablative Material

In the present studies, silicon based low-density ablative material has been studied for its performance to protect flight hardware from temperature raises due aerodynamic forces a longer duration. The oxyacetylene flame test estimates properties at 100–120 W/m2 heat flux. time duration is taken 200 s. shows low mass and linear ablation rate with high effectiveness. degradation kinetics of ablator by Thermo Gravimetric Analysis (TGA) method. Non-isothermal TGA performed in range 30 °C 900 various heating rates, viz. 5, 10, 15, 20 °C/ min. Knowledge kinetic parameters thermal decomposition used predict which faces during aerospace applications. During ablation, silicone consists virgin zone, reaction char zone. These are explained determined help free software called Kinetic Calculation.
