对采用包套轧制工艺及胶粘工艺制备的泡沫铝三明治板进行了准静态三点弯曲实验，分析了材料的变形行为及界面结合强度与失效模式间的关系。研究结果表明，包套轧制法制备的三明治板的极限载荷明显高于胶粘三明治板，具有界面冶金结合特征的泡沫铝三明治板的失效特征体现为剪切失效与面板凹陷共同作用。通过叠加原理修正了相关的模式公式，该模型具有较高的精度，可对预测三明治板极限载荷提供理论依据。

The sandwich structure with metallurgy bonding interface and glu-bonding interface were carried out by the static three-point bending test.The effect of material deformation behavior and interface bonding strength on the failure mode were investigated.The results showed that the limit load of sandwich structure during pack rolling process higher than those with stickiness technology,the failure characteristic of sandwich structure with metallurgy bonding interface was the combination of core shear failure and indentation.We cor-rect the related model through applying the superimposition effect of indentation and core shear failure to pro-vide a theoretical basis for the limited load of sandwich structure.
