摘要
In this paper, experimental investigation and theoretical analysis are earned out in an attempt to study the response of SiC ceramic matrix composite reinforced with three dimensional braided fabric(3D C/SiC) under high velocity impact. The results show that 3 D C/SiC composite will be turned into comminution if the pressure of the impact point resulted from the projectile impacting 3D C/SiC composite sample is larger than 780Mpa. Based on the analysis of the mechanism of composite comminution, a theoretical model has been developed.
