I totally agree with everything you are saying. But you have to consider the application of said material. A bike frame that bends is a failed part and it does not matter how much more force it can resist, it is now useless. I also am speaking of catastrophic failure by the way, as in there is no bike anymore after this crash type of incident. In these cases, I believe the carbon bike will endure a greater amount of force than a steel bike. And that's also while being far lighter because at equal weight there is really no contest.
Well at this point we're talking fundamental properties, yeah, CF is stronger in tension than steel or aluminum, for less weight.
I guess the crux of my argument is that details like layup and such are critically important, mainly cuz the applied force cannot accidentally be permitted to focus on a small area and break the fibers there, repeat repeat repeat, progressively destroying that part.
At least metals are generally consistent in their properties in multiple directions. I'd need a lot of reassurance, technically, before I flew on anything with a fully carbon wing, particularly as the wing ages.
