摘要 利用材料试验机对玻璃钢(FRP)夹芯板面外压缩性能进行实验测试与模拟研究。结果表明:夹芯板面外压缩变形可分为弹性变形与断裂两个阶段。蜂窝芯中part 2胞壁厚度t1与part 2高度h比值t1/h较大时,夹芯板以屈服方式变形;t1/h较小时,夹芯板以屈曲方式变形。蜂窝芯中part 2为夹芯板主要承载构件,蜂窝芯中part 1与part 3对part 2起到固支作用,面板对蜂窝芯起到固支作用。蜂窝芯中part 2胞壁厚度为夹芯板面外压缩抗压强度影响的主要因素,蜂窝芯胞壁边长影响次之,而蜂窝芯中part 1,part 3与面板厚度的影响较小。夹芯板总高度一定时,随着蜂窝芯层数增加,夹芯板抗压强度逐渐增大。

Abstract:The experiment and simulation investigations on out-plane compressive characteristics of FRP sandwich panel were conducted. The results show that two deformation stages are elastic deformation and fracture stages in out-plane compressive deformation. The yielding mode deformation as t1/h which is very big,while the buckling mode deformation as t1/h which is very small. The part 2 in the honeycomb core is main bearing part for sandwich panel,and the part 2 is supported by the part 1 and part 3 in the honeycomb core,while the honeycomb core is supported by the panel. So,the cell wall thickness of part 2 has the most significant influence on the compressive strength,and the influence by the cell wall side length of honeycomb core is the secondary,while the influence by the cell wall thickness of part 1 and part 3 in honeycomb core and the thickness of panel is the weakest. When the honeycomb core height is fixed,the compressive strength of FRP sandwich panel gradually increases along with honeycomb core layers increase.
