Top-down design of tailored fiber-metal laminates
- 228 Downloads
Researchers at the University of Paderborn have developed a top-down approach for the design of fiber-metal laminates. The thickness-dependent characteristics profile of the multi-layered material is derived from full-vehicle simulations. The researchers are also focusing on inherent transitions between the different layers’ stiffness gradients, as well as good formability.
Drawbacks of Single Materials
Automotive lightweight design is a considerable measure to meet the worldwide need for reducing CO2emissions. This led to an excessive portfolio development of conventional metals like steel or aluminum in the last decade. However, the lightweight potential of common materials like steel, aluminum or even fiber-reinforced plastics is limited. High-strength steels play a significant role in the design of safe and light car body structures. Nevertheless, the high density and buckling problems related to reduced sheet thickness limit the achievable mass reduction. Aluminum alloys are...
