Numerical simulation of dynamic ablation of carbon fiber composites

In order to carry out the high temperature ablation analysis of carbon fiber composites, the dynamic ablation numerical simulation of carbon fiber composites is carried out in this paper, and the high temperature ablation experimental results and calculation results are compared and analyzed. The results show that the ablation of the material is the result of multiple factors. With the increase of ablation time, the heat flow into the material reaches equilibrium. Compared with the experimental results, the error of the predicted ablation amount of the dynamic model is less than 10%. The dynamic calculation numerical method can truly reflect the ablation characteristics of the material.
