摘 要：The aluminum sheet/powders/aluminum sheet sandwich rolling process which was applied to manufacturing precursor of foam aluminum sandwich panel was put forward. The purpose of sandwich rolling was to obtain high densification precursor and bonding of metal face-sheet/ powders interface. Compared with mold-compacting, powder densification process and deformation characteristic of interface were studied for the first time in the process of aluminum sheet/powders/aluminum sheet sandwich rolling. The experimental results show powder deformation is a continuous deformation process. Elastic deformation and plastic deformation were produced in powders, thus powders became lamellar structure under rolling pressure. Powders were compacted bonded and atomic force formed among the powders. Metal aluminum sheet exposed fresh metal surface under tensile rolling force. Powders near the interface filled the fresh surface of the metal face sheet and bonded each other.
