摘要：
A sandwich rolling processing technique was proposed for preparation of aluminum alloy foam sandwich with a metallurgical bonding interface. The practical bonding property of the interface and the bending resistance were demonstrated using three-point bending tests carried out with the prepared aluminum alloy foam sandwich panel. By analyzing the load-deflection curve, deformation behavior of two kinds of porosity sandwich panels was discussed. The deformation behavior was obviously different between two kinds of porosity sandwich panels. Both bending strength and bending elastic modulus of low porosity (58.81%) sandwich panel were larger than those of high porosity (76.21%) one. Both fracture energy and fracture deflection of high porosity sandwich panel were higher than those of low porosity one. The experimental results can be technological guidance to the practical design of the foam aluminum sandwich in the industry.
