Abstract

The sheet formability of single AA5182 sheets and sandwich sheets comprising of AA5182/polypropylene/AA5182 (AA/PP/AA) was studied. Rolling without lubrication and subsequent recrystallization annealing led to the formation of favorable ｛111｝//ND fiber textures in AA5182 sheets, which provided a higher plastic strain ratio of $R_m=1.5$. $R_m$ value of 1.58 was obtained in the AA/PP/Ah sandwich sheet sample. Furthermore, a proper combination of the sample direction of the upper and lower skin sheet gave rise to an optimization of the sheet formability of the sandwich sheets.
