That's just a type of Carbon Fibre.

Easton already produce such frame material iirc, from some Scientific Materials mags or something. (i.e Carbon fibre utilising nanotubes, and produced in to bike frames)

Graphite? Like how golf club shafts are made just bigger tubes? Then possibly lugged with something light aswell as i dont think you can make non straight tubes with it or weld it.

Graphite is carbon ;-)

Though I have to be honest, I do not know much about golf clubs, lol.

But I would assume that what they (golfers) call 'graphite' is actually carbon fibre and not graphite (e.g. what you see in pencils and as a very slippy slidey material based on the fact it it layers of graphine (which are just atomic thick layers of carbon sheets as such) as also very brittle.
