I understand that it does not do well beyond it’s yield point. What I’m saying is that this yield point is higher when you are comparing specific applications like a bike frame for example. In the video, you can clearly see that the same force (in this case impact) just ruins the aluminium frame while the CF bounces back, repeatedly and while increasing the force applied. I am not saying that it’s completely fine and safe, I’m saying it’s still a usable bike frame even if unsafe if we are speaking peak strenght. This can make the difference between being able to ride back home and being stranded.
