| Main themes |
The course is divided in six main chapters following an introduction :
0 Introduction to polymer processing and the phenomenology of rheometrical flows
1 Shear dominated flow : capillary flow, flow in a die and flow in a screw
2 Capillary and rotational rheometry
3 Elongational flow and rheometry
4 Processing and rheology of complex polymer systems : an introduction
5 Chemical aspects of polymer processing
6. Polymer processing technologies.
|
| Aims |
The objective of the course is to familiarize the students with various aspects of polymer processing and rheometrical methods suited for polymers with a focus on thermoplastics.
At the end of their classes, students will be able to understand and explain:
1. the scientific foundations of polymer processing (physical as well as chemical aspects);
2. the main measurement methods of polymer rheology and their scientific basis;
3. the fundamentals of the rheological behaviour of complex polymer systems;
4. the major polymer processing technologies and rheometrical techniques.
Moreover, the students will be able to use the concepts for the resolution of concrete problems in the context of case studies and laboratories.
