摘　　要：通过对不同的z-pin角度、面板厚度、去除泡沫处理的X-Cor夹层结构试样进行平压性能试验和分析比较,得到其破坏模式及不同设计参数对性能的影响。试验结果表明:X-Cor夹层结构中z-pin和泡沫存在协同增强效应;增大z-pin端部约束和减少z-pin的植入角度能提高平压性能;但z-pin角度为0°的夹层结构平压性能对植入角的角偏差缺陷更敏感,缺陷的存在影响承力性能。Comparison tests of compressive properties were carried out on different z-pin angle, face skin thickness ,with and without foam, which could be acquired the failure modes of X-Cor sandwich and the effect of different design parameters on compressive properties. Experimental results show that the combination of z-pins and foam core lead to a synergistic strengthening. Increasing restriction of z-pin＇ s end and decreasing the angle between z-pin and face sheet can enhace the compressive properties. But the compressive properties of z-pin angle with 0° are more to sensitive to angle deviation error, and it directly affects behavior of perfect mechanicals properties.
