The objective of this study was to develop formability evaluation techniques in order to apply aluminum sandwich panel for automotive body parts. For this purpose, formability evaluation by using FLD (forming limit diagram) was carried out in order to secure the fundamental data for the measurement of sheet metal forming and the establishment of optimum forming conditions of the aluminum sandwich panel. From the results of these formability evaluation, the formability of aluminum alloy sheet which was the skin component for the sandwich panel was higher than that of sandwich panel. In addition, the formability of sandwich sheet which was made by present study was same as that of sandwich panel made by foreign country. Also, it was found that sandwich panel made in present study could have the excellent deep draw-ability when it was compared to the foreign made sandwich panel.
