An open-cell nickel foam was joined with a polymethyl methacrylate (PMMA) sheet with a thickness of 1.0 mm by friction stir incremental forming (FSIF) process under rotation rate of the tool faster than 2000 rpm and feed rate of the tool slower than 60 mm/min. The joining strength between the foam and the sheet was obtained over the fracture strength of the foam in uniaxial tensile test. On the other hand, the compressive specific strength of the foam–sheet composite was obtained approximately 33 times higher than that of the foam in uniaxial compression test. This was due to not only high specific strength of the sheet but also sandwich structure of the foam–sheet composite.
