I don't think so epoxy is hard but not hard like metals. On small sections my worry would be adhesion and differential expansion, on larger sections I wouldn't worry at all. Carbon is stiffer relative to the fiber reinforcements, the plastic around the carbon fiber is likely some kind of epoxy so there is compatability on expansion ratios and such. You can easily cut epoxy or carbon composites with metal hack saw, even one one made out of sheet metal, untempered. Epoxy hack saws would have little effect on metals.

Last thing last night I tripped over a 2 pack of epoxy in my bedroom. came right down with 200# + on the plastic gal of hardener. Lucky it didn blow up all over the place. Livin the life!
