Understanding Polymer Durability in Critical Applications

The course content will include:

Introduction to polymer types 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 - presents an overview of the 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 - describes the various methods that can be used to test and evaluate the long-term performance of plastics and rubbers. Typical ageing techniques and testing methods will be discussed including creep, relaxation and 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. Here, the various methodologies used to accelerate long-term testing will be introduced 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 will also be covered.

Plastic and rubber durability examples - examples of case studies of designing with long term properties in mind and the generating relevant accelerated test data will be shown.
