Multi-criteria optimisation of in-situ reorientation processes for defined graded profile structures (A01)

• Subject Area: Lightweight Construction, Textile Technology ; Plastics Engineering ; Mechanics
• Term: since 2025
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 525069572

The sub-project focuses on dedicated grading of profile structures by injection moulding. For this in-situ re-orientation process the interactions between material-specific and structural-mechanical parameters are to be described as a function of manufacturing effects. This complex multi-physical process of fluid structure interaction requires an optimal setup of process parameters assuring high reliability, stability and repeatability achieved by a multi-criteria optimisation with robust and efficient simulations including modified failure and damping models for graded composites locally distributed fibre lengths and orientations.
