What is Carbon Carbon?

[Hypercat]

I heard about this new composite material, its not graphite or carbon fiber it's called Carbon Carbon and my understanding is it resists higher temperature but I cant find any information about it.

It's not new. It's used in high temperature aerospace applications. It's a relatively brittle ceramic matrix composite. It has no boat application unless you're using rocket propulsion.

Look at the nose cone on the space shuttle- that is carbon-carbon. It resists high temperature all right, can take 15,000 degrees Celsius or more but rather poor structural properties. It is more for handling extreme high-pressure high-temperature plasmas than for anything a boat would see.
