Physical properties of organic materials

2M1AC2 Physical properties of organic materials Materials and Chemistry S8
Lessons : 7 h TD : 0 h TP : 8 h Project : 0 h Total : 15 h
Co-ordinator : Sophie Eve
Prerequisite
Notions on the structure of polymers
Course Objectives
The objectif of this lecture is to describe the relationships between the mechanical properties of polymers and the motions of the macromolecules allowing (or not) the deformation of the organic materials. The influence of different intrinsic factors (such as the composition and the structure of the polymers), or extrinsic factors (such as the temperature or the deformation speed) on the mechanical behaviour of the materials will also be described.
Syllabus
- Tensile behaviour of polymers: structure - properties relationships
- Linear viscoelasticity
- Plasticity of polymers
- Damage and rupture
- Effects of adjuvants adding and shaping
Practical work (TD or TP)
8h of practicals associated to the lecture (2x4h) :
- one practical to observe different behaviours of polymers in tention (brittle rupture, ductile deformation, anelasticity, plasticity)
- one practical on semi-crystalline polymers and the differences in behaviour related to the degree of crystallinity (tensile behaviour, thermal properties, stress relaxation)
Acquired skills
Understand the different factors that influence the deformation of polymers materials, and thus be able to choose the conditions to apply during the shaping of a plastic, or choose the material (or composite) that will as best resist to the conditions in use.
