Objectifs: Polymer processing represents a growing economic activity. Polymer parts (films, tubes, profiles, bottles, various injected moulded products for automotive industry or domestic appliance...) require mechanical, optical, barrier properties. The objective of the course is, first, to present the main thermoplastic polymers and their forming tools, then to provide the main rheology, physics and mechanical insights which govern the processes, and finally to apply these knowledges to the most popular polymer forming processes (extrusion, injection, blow moulding...).
This course is devoted to students who are interested both in material physics and modelling and who want to improve their knowledges on polymer and polymer forming. We will focus on what is original in structure, properties and forming processes of polymers when compared to those of other materials
Programme: Summary : Thirty slots : lectures, experiments, exercises
- Economic and technical aspects of polymer industry
- Rheology of molten polymers
- Amorphous and semi-crystalline polymers, crystallization kinetics, orientation
- Thermal phenomena in polymer forming
- Experimental and theoretical investigation of extrusion, injection moulding, blow moulding
- Basic principles of polymer processing modelling
- Mechanical properties of polymers
Half of the courses will consist in experimental practice: rheology, mechanical properties, crystallization, injection moulding, blow moulding
Niveau requis : This course needs prerequisites in continuum mechanics, heat transfer, thermodynamics and crystallography.
Modalités d'évaluation : It consists in a short report on one of the practical work done by the students during the week.
