Hybrid Joints - Lightweight Automotive Engineering by the Use of Multi-Material Design

Tim Schleicher

Research output: ThesisDiploma Thesis


With the increasing political pressure on the automotive industry to reduce CO2 emissions, engineers are forced to come up with lightweight solutions. The idea of using the right material at the right place results in multi-material structures with joining technologies of such structures as a critical part. The main goal of this diploma thesis is giving an overview of the present multi-material joining technologies with respect to their process limits. In a first part, the different methods are listed in groups which are represented by process characteristics. Within the second part, the mentioned joining methods are evaluated and compared from multiple points of view with respect to automotive mass production. These views guide the way to the identification of economically producible and well performing multi-material joints for different use cases in automotive engineering. The third part of this diploma thesis presents an exemplary choice of a joining technology for a specific scenario (multi-material-multi-geometry substructure) in automotive engineering and especially the methodology to do so. Further, the results of the applied methodology can be used as an identification process of future interesting research fields/projects with exemplary characteristics like multi-material joinability, joint and joining characteristics.
