Temperature control prior to testing
We planning the the steady-state temperature tests we identified a problem related to the secondary curing of the samples during the initial heating up of the environmental chamber. In order to ensure consistency between the samples we would like to ensure that the same amount of energy is absorbed by each test sample during this period. Hence the increase of temperature would look like this:
The proposed method allows for the total energy (area below each curve) to be approximately the same between each sample. However, it is not known to what extent heat and curing time contribute to the overall cure level and it is impractical to try and establish such relationship.
Instead we plan to adopt a more pragmatic approach. If the temperature varies between each test we will simply use a constant heating time. Each test will be conducted at one of the test temperatures (1-n).
