Composite Technology/Lightweight Construction
The Focus of the department Composite Technology/Lightweight Construction is on the mechanical design and process technology of highly loaded lightweight structures.
Highest mechanical properties at low weight: The portfolio of services ranges from idea generation and concept development to design, simulation and optimization to the construction of prototypes and component testing. New, sustainable materials allow future-oriented solutions for the cost-efficient lightweight construction and parts of tomorrow.
