RESEARCH FIELD OF THE SFB/TRR 402
The SFB/TRR 402 is dedicated to researching the mechanisms of action in the production of plastic-based lightweight structures with load-dependent 3D grading of the reinforcing structure. 3D grading promises a significant weight reduction of fiber-reinforced plastic components through production processes that allow a targeted, controlled alignment and distribution of the fiber reinforcement in critical load areas.
To this end, 17 sub-projects are researching the fundamentals for controlling the production processes, their simulation and data-driven analysis and synthesis.
RESEARCH INTO A SUSTAINABILITY-ORIENTED PLM STRATEGY
Together with the Chair of Anthropogenic Material Cycles at RWTH Aachen University, the Chair of Virtual Product Development at TU Dresden is researching the fundamentals of product life cycle management and life cycle analysis for eco-design of new production technologies in sub-project C07. The focus is on researching methods for holistic, cross-lifecycle environmental modeling and assessment as well as their integration into product lifecycle management strategies.
Furthermore, the foundations will be laid to enable well-founded decision-making during the conception and design phase with regard to the sustainability and recyclability criteria of the technologies researched within the Transregio. The decision-making methods will be realized and tested in parallel by designing and implementing a prototype expert system.
The use cases and data required for testing and validation are generated through cooperation with the Institute of Lightweight Engineering and Polymer Technology (ILK) at TU Dresden and the Institute of Plastics Processing (IKV) at RWTH Aachen University. In addition, further coordination with all other Transregio sub-projects ensures the broad applicability of the concepts and methods developed.
THE INTELLIGENT DEVELOPMENT AND PRODUCTION SYSTEM
Within the Transregio, the Chair of Virtual Product Development is involved in the development of an intelligent design and production system (iDP). As the central vision of the Transregio, the iDP will process and make available its scientific findings and form a comprehensive tool for the use of the researched and developed production processes for 3D-graded fiber-reinforced plastics.
We are very much looking forward to working with our partner institutes on sustainability and cross-life cycle data management from the start of research into this new, promising production technology.
