Yes. If I absolutely must use a fiber filled material, I prefer glass fiber rather than carbon. A fiber fill in your filament reduces shrink and warping and increases rigidity, and makes some tough-to-use polymers more printable such as Nylon. However, the above is correct in that it reduces tensile strength and especially layer adhesion strength, i.e. tensile strength along your Z axis. (Plus, carbon fiber fills basically always limit your color selections to black, black, and black.)
If you need mechanical strength of some type or another, it's almost always a better idea to use a non-filled filament in a more suitable material and work on modifying your printer or getting a better printer that's capable of printing that material. I can do straight polycarbonate in my machine with a pretty high degree of success (other than very small parts, I'm finding) so in all honesty I don't have much use for fiber filled filaments anyway.
