Well how confident would you be that this part isn't exposed to temperatures above that glass transition temperature? It is installed near the engine.

The report further states that the part included in the original design (part of the kit) was made of a carbon fiber composite where the epoxy had a listed glass transition temperature of 84⁰C. If there is an element to be critical of along these lines it's that the part as originally designed is supposed to include an aluminum tube at one end that may stiffen the part - the report makes no conclusions whether it truly would have, but notes that the actual glass transition temperature was found to be much lower than listed, and lower than that of the epoxy used in the original design.

Installed _on_ an engine that operates at 200ºC!
