Objective of this paper is to research the damage characteristic of ceramic-metal interpenetrating phase composite (IPC) under dynamic loading.To this end,uniaxial dynamic compression was performed to characterize the failure of SiC/Al composite with 15% porosity using a modified SHPB.High speed photography was used to capture the failure procedure and set up the relationship between deformation and real stress.The deformation control technology was used to obtain collected samples in different deformations beard dynamic loading.Micro CT technology was utilized to acquire real damage distribution of these specimens.And then,SEM is employed in comparing the damage characteristic in IPC.A summary of the available experimental results shows that IPC without lateral confinement formed double cones.The different feature compared with ceramic materials without restrained is shown to be the result of the lateral restraint effect provided by metal phase to ceramics skeleton.
