Abstract：

Warpage deformation is prone to occur during the traditional rolling process of Cu/Al laminates, and the new corrugated roller rolling has a positive effect on improving the warpage deformation. Therefore, in order to explore the influence laws of corrugated roller profile parameters on the warpage of rolled Cu/Al laminates, with the help of numerical simulation method, the influences of corrugation amplitudes and period of roller on the warpage of rolled Cu/Al laminates were studied. The results show that for Cu/Al laminates with a given initial thickness, the warpage curvature first decreases and then increases with the increasing of corrugation amplitude, and increases with the increasing of corrugation period. When the corrugation amplitude of corrugated roller is 0.2 mm and the corrugation period is π mm, the Cu/Al laminate rolled has the smallest warpage curvature. The research results can provide technical reference for the preparation of Cu/Al laminates with high quality of plate shape.
