Abstract：

The tensile-shear strength is an important indicator for evaluating the quality of rolling bimetallic composite sheets, which is affected by many factors such as material properties, thickness proportion, rolling speed, rolling temperature and reduction rate. For the rolling Cu/Al composite sheet with the thickness of 10 mm, the influence laws of thickness proportion on the length of rubbing rolling zone and the tensile-shear strength were analyzed by numerical simulation and experimental methods. The simulation results show that the length of rubbing rolling zone increases with the increasing of thickness proportion for Cu. Furthermore, the measured results of tensile-shear strength for the rolling Cu/Al composite sheets show that with the increasing of thickness proportion for Cu, the crack on the copper side of tensile-shear separation surface perpendicular to the rolling direction increases, and the tensile-shear strength increases. When the thickness proportion of Cu accounts for 50%, the crack on the copper side of tensile-shear separation surface is the most, the rubbing rolling phenomenon is the most obvious, and the length of rubbing rolling zone and the tensile-shear strength reach the peak. Thus, the above research provides valuable reference for preparing high-strength bimetallic composite sheets.
