The production of metallic sheet composites (layered, multi-material structures) by rolling is a manufacturing route that enables the integration of complementary material properties within a single product. This poster investigates the rollability of different composite architectures, with emphasis on how the layer arrangement, material pairing, rolling schedule (pass design), and process parameters influence final product quality. Special attention is paid to layer co-deformation and interfacial stability, as these factors largely define structural integrity and the viable processing window. The methodology combines targeted experimental pass design with numerical modelling. The rolling schedule is defined in multiple steps, including the total and per-pass thickness reduction and the rolling mode (cold/hot, pre-rolling and subsequent rolling), aiming to achieve deformation with minimal relative displacement (slip) between layers. The modelling approach is used to evaluate stress-strain states, deformation compatibility of the layers, and interfacial loading conditions. Product quality is assessed using multiple criteria: layer thickness uniformity, dimensional accuracy and shape defects, surface integrity, and interface-related defects with a focus on bonding reliability. The expected outcome is a practice-oriented overview showing which pass-design logic and parameter ranges lead to stable layer co-deformation for various metallic sheet composite structures, and which critical factors may trigger quality degradation or unreliable bonding. The presented framework supports rolling process design and quality prediction of layered sheet composites in both research and industrial applications.
