This study aimed to investigate the formability of multilayer sheets in the deep drawing process. The three-layer sheets comprised a sandwich structure of aluminum 1050, a 304 stainless steel mesh, and another aluminum 1050 layer, produced by roll bonding. This configuration was examined to increase the limiting draw ratio and enhance formability. Experimental tests were performed under lubricated conditions on sheets annealed at 250°C and 350°C to assess the influence of temperature and lubrication on final drawing depth and part quality. Alongside the experiments, numerical simulation of the deep drawing process was conducted using ABAQUS 6.14 to predict the final cup depth and analyze stress and strain distributions during forming. Simulation results were compared with experimental data to evaluate modeling accuracy. The results showed that the steel mesh in the core layer markedly increased composite strength without substantially impairing formability. An annealing temperature of 350°C was determined as the optimal condition for maximizing drawing depth. The maximum cup depth achievable without failure was 10.1 mm, corresponding to a limiting draw ratio of 1.53. These findings demonstrate that multilayer sheets reinforced with stainless steel mesh, when combined with proper annealing and lubrication, can significantly improve formability in deep drawing.
