Carbon Fiber X Beam Prototype Testing
I got a test sample of the new CF X beam that Brazuka is trying to bring to market. I heated it up in 10° increments, kept it 10min at steady state, then quickly tested it by clamping it to the desk and twisting it with a wrench. It's not a perfect test setup by any mean, but it can give some indications for the temperature resistance.
In the attached videos it was tested at ambient - 70° - 80° - 90° -100° - 110° - 120° (video 1-7). I'm impressed, up to 100° I didn't feel any difference, at 110° I am not sure if I felt a difference, at 120° it was slightly softer. I then kept it at 105° for one hour, and it once again felt perfectly fine (video 8). These results line up with the datasheet of the resin used, that has a 125° onset Tg.
From these simple tests I think it would fare good in a 90° chamber, so it would be a great X beam for most people.
Handling it a bit I can say that it also feels like a tank, much stronger and stiffer compared to the old one. You can see pictures of me trying to compress the old and the new one with a clamp.
The old one buckled, then failed and cracked while the force required wasn't much, while the new one required much more force, bottoming out where my hands were slipping, and it still didn't buckle.
