摘要：

A novel method of compound casting with hot-rolling to prepare foamable precursor sandwich (FPS) is proposed in this paper, and aluminum foam sandwich (AFS) was obtained by subsequent foaming. The cores and interfaces of FPSs and AFSs made with different rolling passes were investigated. The results indicate that increase of the rolling pass can improve the foaming capacity of FPS, cell uniformity and interface bonding quality of AFS. The differences in load resistance and energy absorption of AFSs made with different rolling passes were compared under three-point bending tests. It is found that the deformation uniformity of core cells increases but the overall load resistance and energy absorption of AFS decrease with the rolling pass. The evaluation of facesheet/core interface effect on the load resistance and energy absorption of AFS showed increasing the facesheet thickness and rolling pass is a good way to enhance the load resistance and energy absorption for AFS.
