Job description:

Background and objective of the work:

The DLR Institute for Vehicle Concepts is researching innovative vehicle structures that reduce vehicle weight through intelligent lightweight construction and thus contribute to environmentally friendly mobility. One possible innovative approach is the use of thin-walled concrete-based materials for the vehicle structure. Concrete production has one of the lowest CO2 footprints (per kg) of all building materials to date. This makes it an attractive solution to reduce the life-cycle emission of CO2 for vehicles. In addition, concrete-based materials have a low density, high compressive strength and high specific fracture energy. This material is very versatile and can be casted into complex and intricate shapes.

The aim of this work is to create generic parts, comprised mostly of thin-walled concrete-based materials, in order to progress the future design of mobility. Current vehicle structures are to be analyzed to identify the application areas, requirements and limitations of the concrete-based material. The concrete-based material performance will be evaluated and analyzed by fabricating and testing specimens. There will be an emphasized analysis on the potentials of fiber-reinforced concrete. Based on the performance of the material, it will be further optimized to maximize its performance. In the end, a structural component will be casted at the ILEK with their expertise and structural testing will be done at DLR.

Content of the work:

Literature review of current technologies and applications of concrete-based materials Application, requirements and limitation analysis of concrete-based material within automotive structures Manufacturing, mechanical testing, and optimization of the concrete-based material Design consultation and selection of final structural component with the aid of a simulation engineer Manufacturing of the final structural component, structural testing and assessment of the results Documentation of the findings and results
