This paper aimed to study the superalloy honeycomb sandwich structures. The out-planethree-point bending behavior are investigated by experimental method and FEM. The failure mode are obtained by experiments; The finite element method is used to analyze the impacts of the panel thickness and welding angle on the mechanical properties.%本文通过力学实验和有限元模拟方法研究了金属蜂窝夹层结构的静态力学性能。通过三点弯曲试验分析了不同结构参数下的破坏模式；通过有限元方法模拟了不同面板厚度、不同焊接角度的蜂窝夹层结构的弯曲性能。
