Porous aluminum is a lightweight material with high energy absorption properties. In this study, porous aluminum core sandwich panel consisting of ADC 12 porous aluminum and dense ADC6 plates was fabricated by friction stir processing (FSP) route. In the FSP route, both fabricating ADC12 precursor and bonding the ADC12 precursor to dense ADC6 plate can be conducted simultaneously. It was shown that fabricated sandwich panel has good bonding between ADC 12 porous aluminum and dense ADC6 plates. Also, lightweight sandwich panel, which has porous aluminium core with porosity of higher than 70 %, can be successfully obtained.
