To simulate ageing and degradation of a plastic material PBT containing 10% of glass in the lab, I am trying to run humidity, wetting, and drying processes. From samples
gathered from the field this material have had cracks appearing in the finished assemblies. This material is suspected to have shrunken over time.
Basically my question is in order to age and degrade this material severely and quickly what should be the sequence in the cycle? And how can I test the material shrinking theory?
Option #1
Humidity @35°C
Drying @60°C
Wetting@25°C
Option #2
Wetting @25°C
Humidity @35°C
Drying @60°C
Or any other test sequence suggestions. In our lab I also have the ability to run thermal, corrosion, and various mechanical test.
