N2 - The Thermal Protection System of the spacecraft will inevitably suffer the external shocks in service. 2D plain-woven C/SiC (2D-C/SiC) composite is a typical ceramic-matrix composite, which has been widely applied in the thermal protection structure. In this paper, firstly, the experiments that the steel balls impact to 2D-C/SiC composite under the velocity of 79 m/s ∼ 219m/s are investigated by using the air gun. Secondly, the material parameters of 2D-C/SiC are obtained based on an orthotropic constitutive material model in Autodyn, and numerical simulations corresponding to experimental conditions are carried out based on Smooth Particle Hydrodynamics method. The comparisons of the debris cloud structure, the B scan results and the axis velocity of debris cloud between the calculation results and the experimental data validate the ability of this model for describing the brittle characteristics and the softening behaviour of 2D-C/SiC under the impact load. Finally, the limit penetration depth of 2D-C/SiC under the impact by steel ball is predicted based on the simulation results.
