Hybrid design as a contribution to sustainability
Projects of the Automotive Lightweight Design Group | LiA
Various research projects have demonstrably shown that the combination of different materials to form a hybrid system leads to advantageous component properties. However, a decisive contribution to sustainability can only be guaranteed if the resulting energy requirement during material provision, production and the utilization phase is lower than for comparable components made from homogeneous material systems. Life cycle assessment (LCA) serves as a tool for evaluating the environmental impact of hybrid construction methods.

Correlation of microstructure and corrosion of additively manufactured aluminium components
Due to their good corrosion resistance, the demand for Al alloys from additive manufacturing processes in industrial applications is increasing rapidly. However, recent studies show a crucial dependence of the corrosion resistance on the microstructure of the Al components. By means of nano-additives (SiC and TiC), the microstructure of AlSi10Mg components could be significantly modified, which consequently also affects the corrosion resistance of the components. In this study, the microstructure of the heat-treated components could be correlated with the corrosion properties.

Hybrid lightweight construction made easy
At the Institute for Lightweight Construction with Hybrid Systems (ILH) at the University of Paderborn, more than 170 scientists are researching novel lightweight construction technologies. As part of the HyOpt project, a team of ILH researchers and industrial companies is dedicated to developing an automated approach for the design and production of hybrid multilayer composites with customised functional properties.

When it gets damp in the material
In close cooperation with the Chair of Technical and Macromolecular Chemistry, the Chair of Plastics Technology Paderborn is researching the macro- and microscopic interrelationships of the degradation reactions and, together with several industrial partners, is developing recommendations for action for material selection and processing conditions.

Hot forming process-integrated surface structuring for hybrid components
In cooperation with the Institute for Machine Tools and Production Engineering at the Technical University of Braunschweig, scientists at the Institute for Lightweight Construction with Hybrid Systems / Lightweight Construction in the Automobile have developed a process that integrates surface structuring in the press hardening process. The structuring ensures improved bonding of fibre-reinforced plastics to the metallic base component.
