I would put "stress concentrators" as a (singular, but definitely not the only) reason that sharp angles aren't used with carbon fiber bike frames. Sharp angles tend to try to take all the stress they can, in general... and in the case of carbon fiber, it'll be very not pretty when (if) it breaks, particularly if somebody happens to hit the break. There are ways around this--like more material on the sharp corners--but it's generally better to not have the corner quite so sharp in the first place.
