The lighter the better. That is the golden rule, at least in the automobile, aircraft and aerospace industries. Materials like fiber-reinforced plastics and light metals are paving the way for components with lower densities. The firm and secure fusion of different materials poses a major challenge, however, which is why researchers from the Technical University of Munich (TUM) are working on ways to improve joining techniques - for example by laser surface treatments.
