It bears stating again: Aluminum does not “fail suddenly”. On the other hand, steel does. I’ve broken both...twice.

Although I haven’t broken anything that is carbon fiber, I would say that given the way in which carbon fiber is used, it would be difficult for the material to propagate a crack across the various layers of fabric. It would tear rather than fracture and a tear is a much slower failure.
