A friend from work used to work in Ontario at a carbon fiber business. They made specialty CF parts for race cars like splitters, wings and other structural parts.
He brought one of the rotors they used to make for the Lola racing cars they built parts for. Here are some pics.
The rotor has a graphite core with pressed carbon fiber as the friction surface. These are super light and huge.
Wear indicators. This rotor was only on for a short test run so there is plenty of life left.
I asked him if he could get more of them so I can have one (hopefully 4 of them). :afrocool:
I believe pads of the same construction are used. Both the rotors and the pads wear heavily and require replacement during a race (at least during an enduro).
I wonder why they dont do 380si aluminum rotors like the cyl walls in my proto block. The aluminum would disperse the heat so well, they would last forever, and they would weigh nothing. The down side would be that you would have to run iron pads, which would probably make a lot of noise.

Probably warp the shit out of them. Also aluminum starts getting sticky really quick. On top of that, I thiiink brake rotor temperature can exceed the actual melting point of aluminum if you're getting on them enough?
This is very cool: http://www.imp.mtu.edu/information/brake_rotor.htm
Aluminum rotor with bonded steel friction surfaces. They claim the cost for making them is comparable to standard rotors.... but I certainly have seen them in production, so I don't know what come of it.
