Introduction to polymer type and their behaviour
- Understand how polymer structure affects the properties of the material and the differences between rubbers and plastics.
Long-term behaviour and the effects on durability
- Overview of various mechanisms responsible for loss of performance.
- Effects such as viscoelasticity; chemical and thermal ageing; combination effects such as ESC.
Evaluation of long-term durability
- Review of methods used to test and evaluate the long-term performance of plastics and rubbers.
- Typical ageing techniques and testing methods including creep, relaxation, fatigue along with chemical degradation techniques.
Life prediction and accelerated testing
Since real-life testing is impractical due to the long timescales required, it is common that accelerated methods are used:
- Introduction to methodologies used to accelerate long-term testing along with life prediction methods such as Arrhenius and time-temperature superposition.
- How to use accelerated material test data for design purposes and for validation of accelerated product tests.
Plastic and rubber durability examples
- Example case studies of designing with long term properties in mind and the generating of relevant accelerated test data.
