Nothing special about cutting CF, I routinely cut it for guitar neck reinforcement using a chopsaw with a standard fine tooth carbide blade. Since you're cutting a thin-wall section it might be a good idea to place a close fitting wood block inside to prevent any blow-out. It will dull blades if you're cutting a lot of it but I don't cut enough of it for that to be an issue. .
