The possibility of fabricating the metallic bonded truss structured aluminum board was studied by the combination of the roll bonding process and superplastic forming. Al–1.6%Mn alloy sheet was first pre-clad to the superplastic 5083 aluminum alloy sheet. These sheets were piled in three layers and then hot roll bonded. Here, the anti-bond coat was printed on both sides of the core sheet in striped pattern before hot roll bonding. These hot rolled bonded sheets were next subjected to cold rolling to obtain the superior superplasticity. The three layered roll bonded sheets were set between flat dies at superplastic temperature and the truss structured board was formed superplastically by applying the internal gas pressure to the un-bonded area with gradual opening of the flat dies. It was found that a higher pressure and a slower gap opening speed was desirable to obtain a flat surface board. As the results, the truss structured high rigidity board with flat surfaces was obtained.
