Lower, according to the report
"Two samples from the air induction elbow were subjected to testing, using a heat-flux
differential scanning calorimeter, to determine their glass transition temperature. The
measured glass transition temperature for the first sample was 52.8°C, and 54.0°C for the
second sample"
Yeah, they might have used ABS-CF filament, but unless they got it from a good brand that uses good resin and proper printing parameters, the actual Tg will be lower, plus the stress from the vibration/load could have made the part fail if it was not for the heat later in flight.
- CarVac 10mo agoSome manufacturers fudge the Tg. Polymaker Polylite ABS has a claimed Tg of 101°C but the HDT curve clearly shows it starting to lose strength at 50°C, for example.
- brovonov 10mo agoPolymaker's ABS is dubious too because it is blended with PETG. They are coming out with a Pro version that has a higher Tg and requires way higher chamber temps to print properly.
- zuppy 10mo agoby the glass transition temperature, i'm willing to bet it was printed with pla (probably pla-cf).
