蜂窝芯体厚度对Nomex蜂窝夹层复合材料压缩性能的影响

Influence of Honeycomb Core Thickness on Compressive Property of Nomex Honeycomb Sandwich Composites

以NRH-2-48芳纶纸为蜂窝芯体,碳纤维层合板为面板,制备了不同芯体厚度的Nomex蜂窝夹层复合材料,通过压缩试验研究了芯体厚度对复合材料压缩性能的影响,并探讨了芯体厚度与复合材料屈曲载荷和压缩破坏载荷的关系。结果表明:随芯体厚度的增加,复合材料的屈曲载荷和破坏载荷都相应增大,当复合材料的屈曲载荷与面板的破坏载荷相同时,蜂窝芯体厚度最佳。

Nomex honeycomb sandwich composites with different core thickness were prepared using NRH-2-48 aramid paper as core and carbon fiber laminates as panels.The effect of core thickness on compressive property was studied by compression testing,and the relationships of core thickness with buckling load and compressive breaking load were investigated.The results show that with the increase of core thickness,the buckling load and the breaking load of the composite increased.When the buckling load of composites was as high as the breaking load of the panel,the core thickness was the best.
