摘　　要：为研究整体中空夹层复合材料的冲击防护性能,结合冲击试验分析了厚度、基体含量、冲击能量变化对其材料冲击防护性能的影响。实验结果表明:随着材料厚度增加,其冲击防护性能先是有所提升,而后变化趋于平缓;材料的基体含量对冲击防护能力影响明显,在较低冲击能量下,低基体含量就有较高的冲击防护性能,而在较高冲击能量下,只有高基体含量才具有高的冲击防护性能。将整体中空夹层复合材料应用于冲击防护领域时,应根据具体的使用情况设计合理的制作工艺。To study the impact protection performance of integrated hollow core sandwich composite,the impact experiments were done from the thickness,the matrix concentration and the impact energy. The result indicates that the impact protection performance is improved as the thickness increases,but it is not obvious when the thickness increases to a certain extent,matrix concentration will significantly influence on impact protection,and this effect will change with the change of impact energy,low matrix concentration is suitable for low impact energy protection,high-energy protection requires high matrix concentration. We should make a reasonable production process according to the specific situation when applying the integrated hollow core sandwich composite to the field of impact protection.
