摘要

First, the experiments that the steel balls impact to 2D-C/SiC composite under velocity of 79~ 219 m/s are investigated by using the air gun. Second, material parameters of 2D-C/SiC are obtained based on an orthotropic constitutive material model in Autodyn, and numerical simulation corresponding to experimental conditions are conducted based on smooth particle hydrodynamics (SPH) solver. The comparisons between the calculation results and experimental data of the debris cloud structure, the B scan results and the axis velocity of debris cloudvalidate the ability of this model for describing the brittle characteristics and the softening behaviour of 2D-C/SiC under impact load. Finally, the limit penetration depth of 2D-C/SiC under the impact of steel ball is predicted.
