Let me add that CF may be getting a bad rap because of a significant different on how it fails, rather than the fact that it does.

The metals used in frames have varying degrees of ductility, while CF has near zero. This means that when over stressed, say by a crash or road hazard metal frames will protest and announce the problem by bending or buckling rather than snapping.

So when a crashed steel or aluminum frame bends we don't blame the material, and if it should later snap, we know why and chalk it up to our own stupidity in riding a compromised frame.

However, CF being the strong silent type, there's usually no evidence of crash damage, short of a total failure. That means we're given no visible warning of issues, and continue riding a frame that may be compromised. When it ultimately fails, it's hard to trace it back to the earlier event, and we blame the material instead.

Combine that with the underbuilding I mentioned earlier, and you have a recipe for the sudden catastrophic failures that we're seeing.
