Sure it does, means whatever resin/fiber matrix is a good insulator and you are cooking the bore.Look it up...cool to touch on the outside doesn't mean diddly to the bore.
If they can get the carbon matrix (the whole assembly, resin and carbon) to dissipate heat I think it shows promise. I would think if Bartlein is doing this it would be done correctly. I'd like to try one if they have that process down. The bore/blank would be done right with Bartlein doing that part. If the carbon will work as Chamberman posted it would be great.
