Comparison tests of compressive properties were carried out on different z鄄pin angle,face skin thick鄄
ness,with and without foam,which could be acquired the failure modes of X鄄Cor sandwich and the effect of different
design parameters on compressive properties. Experimental results show that the combination of z鄄pins and foam core
lead to a synergistic strengthening. Increasing restriction of z鄄pin爷s end and decreasing the angle between z鄄pin and
face sheet can enhace the compressive properties. But the compressive properties of z鄄pin angle with 0毅are more to
sensitive to angle deviation error,and it directly affects behavior of perfect mechanicals properties.
