I don't know if it will cut carbon fiber or not, but it sounds like laser cutting would probably be your best solution. It's a non-contact method, so your material doesnt move when the cutting is being done. Try taking a sample to a local engraver who does laser engraving and ask them to give it a try. If it works, you can than spend a ton of money for a laser engraver and do it yourself. If your doing quantity production, it's probably the way to go.
