    I read through the report. The pilot believed it to be carbon fiber reinforced abs, which should have had a higher weakening temp than the stock fiberglass part. Apparently it didn’t though. They don’t identify the actual material in the report.

      Well, the pilot was lied to. That is definitely not carbon fiber On top of ABS. You can see where the print is falling apart. I’m certainly no expert, but that poor photo in the article definitely looks like a cheap piece of shit… Relative to what I imagine aircraft parts are like normally

        “carbon fiber” filament usually has little shards of carbon fibers suspended in it. This makes the part less flexible than raw ABS…when cool. It’s not like they do a layup of carbon fiber over 3D printed ABS, that would almost defeat the purpose.

        If they’d done that, 3D print a mold or buck and then do a carbon layup over it, it’d be made of epoxy, which doesn’t melt.

        This was part “only” meant to funnel air into the engine, so I could see why he wouldn’t think it would be a problem. And I think it’s more like the carbon fiber impregnated abs, than coated. I paraphrased the report, so that’s on me.

          Anyone worth their weight in abs knows “carbon fiber impregnated abs” isn’t going to actually do a FRACTION of the job that literal carbon fiber—or even fiberglass—would do, and this pilot is lucky they didn’t kill someone.

          It just goes to show how little people know about carbon fiber and how easily Tricked they are when someone says they mixed carbon fiber into melted plastic… Laughing my fucking ass off

            It’s not the strength they were worried about, it was the temperature at which it weakend, which shouldn’t have been a problem according the the information provided to the pilot.

            I don’t know the material data sheet was wrong or the person selling it to him was wrong or lying. We don’t and won’t know, because they didn’t try to identify it.
