you will find it very hard to cut carbon cloth in less it is pre preg, if you are not aware of what pre preg is it cloth that is pre coated with resin on it that you activate by cooking it usualy around 100deg c. Even if you could cut carbon cloth dry it will fall apart as soon as you pick it up or try do anything to it. You can use a method were you use a spray adhesive to stick the carbon to wax paper which you then wet it out on but you will still get distortion and loose any sort of accuracy. Pre preg is nice stuff to work with but it must be stored in a freezer and must be cooked to cure it and it is also expensive.
