Porous aluminum is a lightweight material with high energy absorption properties. In this study, sandwich panel consisting of ADC 12 porous aluminum and dense ADC6 plates was fabricated by friction stir processing (FSP) route. In the FSP route, lightweight sandwich panel, which has ADC 12 porous aluminum core with porosity of approximately 70 %, can be successfully obtained. Also, fabricated sandwich panel has good bonding between porous aluminum core and dense ADC6 plates. From the result of tensile test of obtained sandwich panel, fracture occurred in porous aluminum core. Therefore, it was shown that the strength of bonded interface is higher than the strength of porous aluminum core with porosity of approximately 70 %.
