Design Chassis

Fraunhofer IWU and the TU Chemnitz have developed a wishbone made of a high-strength sandwich with a metal foam core and hybrid laminate cover layer. The potential is shown in the form of a lightweight wishbone as technology demonstrator, in which the weight reduction leads to a reduction of unsprung masses and thus to a direct improvement of the driving properties.

High Damage Tolerance

Hybrid components made of fiber-reinforced plastic (FRP) composites and metal components make it possible to open up lightweight design applications for complex loads in large-scale production by significantly extending the range of properties compared to monolithic metal structures[1]. Metal foam is therefore very well suited as a sandwich core due to its properties. This applies especially for components that are subject to bending stress, for which flat sandwiches with metallic top layers of aluminum or steel are used almost exclusively. This implies that hybrid core composites and complex...
