alt Hacker NewsThe part was claimed to be ABS-CF. UK AAIB tested the part and found it to have a Tg of approximately 53C. The Tg of ABS is far higher, around 100C. I suspect that the part may have been accidentally printed with PLA-CF (which has a Tg of approximately 55C.)
The original part was fiberglass/epoxy with the epoxy having a Tg of 84C.

Sounds plausible but I guess it's something that they would've confirmed, had it been true
Or it was ABS-CF but they forgot to dry the filament /s
Plastics under load have a lower Tg.
