Modeling of polymer and suspension flows for industrial manufacturing processes

Lecture

The lecture deals with the behavior of (fiber-reinforced) polymers in the molten state and in the context of industrially relevant manufacturing processes. The manufacturing process of fiber composite components has a significant influence on the subsequent component behavior. Accordingly, it is important to map the material behavior during production and the subsequent component behavior. For this purpose, the lecture deals with viscosity and flow modeling of polymers (with and without fibers). The basics of numerical flow simulation are taught and advanced models for the description of industrially relevant manufacturing processes of polymer components are explained. Accordingly, the advantages and disadvantages of different manufacturing processes and their respective modeling approaches are taught. At the end of the course, students will be able to select and implement process-oriented modeling approaches and to mathematically describe the polymer behavior in the molten state.
