Multi material design in lightweight applications is most probable the challenging task of the future. Only the right material in the right place can exploit full use from the positive properties of each material. Under many environmental and economical points of view hybrid structures moved into the center of the interest in different branches. In particular the automotive industry is looking for alternative materials and appropriate joining techniques. Thereby self-pierce riveting (SPR) is a convenient process of joining dissimilar materials like aluminum alloy and composites. In this study semi-tubular self-pierce riveting joints between carbon fiber reinforced laminates (T700SC/RIM935) and aluminum alloy sheets (AlMgSi0,5 T6) were investigated experimentally and then compared to numerical results of a finite element analysis.
