looking for carbon fiber cloth

you can find that kind of cloth at an aircraft material supply company. however you might wanna stick to just traditional means when it comes to prepreg. Usually you need a means to keep it cold at all times until immediatly before you intend to lay the cloth. .also with alot of different types of prepreg you lose the carbon fiber "look" in the process becuase the resin is usually a different, opaque color that permeated the cloth (when it's on an aircraft its gets painted so no one sees it).  I would go fiberglass underlayers which is cheap and then a carbon fiber fashion layer with a little more resin or an epoxy layer over it. carbon fiber cloth itself is relatively cheap (approx $35per yrd) compared to any prepreg material unless you have a cloth freezer handy. that's how I've done it.
