摘要
采用静态三点弯曲加载方式对粘结法制备的泡沫铝夹芯板的力学性能进行研究,通过实验分析不同面板材料和芯层厚度对夹芯板弯曲性能、能量吸收以及失效模式的影响。结果表明:泡沫铝夹芯板的抗弯极限载荷值及吸能性能由面板材料和芯层厚度共同作用,随着芯层厚度的增加,极限载荷强度有所提高,铝面板泡沫铝夹芯板的极限载荷强度和能量吸收能力的增加远高于钢面板的夹芯板;失效模式主要有压入、芯层剪切和面板屈服。
Aluminum foam sandwich（AFS） were tested in three -point bending to characterize their mechanical properties. Tests were performed on AFS with different thicknesses and panel to identify bending properties, energy absorption and failure modes. The results show that the maximum bending load inereases with the core thickness of AFS. The maximum bending load increases as the growth of its thickness in core materials. The maximum bending load and energy absorption of AFS vary with the panel material and thickness. The maximum bending load and energy absorption of Al - AFS are higher than those of the Steel -AFS. The main failure modes include indentation, core shear, face yield.
