I'm writing up the test plan for a carbon fiber composites aileron. The Cert Engineer is asking why I don't do cold temperature wet coupon tests. My only reply right now is that it's not critical compared to cold temperature dry, but I have no concrete evidence for that. Looking back on various test programs I've been involved over the last 40 years, there are no CTW tests, so it's been understood for a long time. Anyone got a reference I can use to put this to bed?

Leading manufacturers are aligning their people, processes, and tools from initial product ideation through to field service. They do so by providing access to product and enterprise data in the context of each personâ€™s domain expertise. However, it can be complicated and costly to unite engineering with the factory and supply chain. Download Now
This whitepaper describes the role of thermal transient measurement to characterize semiconductor thermal behavior. It focuses on the value measurement derived structure functions provide through interpretation of the heat flow path inside a package for use in thermal characterization, failure diagnosis, and improving simulation thermal model accuracy.
