Well, they're probably plenty strong, but...
Carbon fiber has been known to warp/melt if left out in a hot sun for hours and hours in the dead of summer.
Now, what do you think would happen inside a 1400-1800* engine? :O

A diamond is a form of carbon. A diamond is formed when carbon is subjected to extreme temperature and extreme pressure for a period of time. If they were made from a durable form of carbon they might work,but, I doubt if they are made of the same stuff that everybody likes to use to make a hood.
Although I am new to RX7s and new to this forum and I am by no means an expert when it comes to apex seals, I personally would stick to something more conventional.

I'm just glad nobody has thought of my idea yet regarding apex seals...

a similar material is used for the seals in our air pumps though. i think it's made out of flax cloth and a curing agent or something. it's self lubricating with good wear properties. the reason i know is i took a spare one apart and ended up cleaning it out and reassembling it to put on my car.

There are many forms of carbon, but "carbon" itself is actually amazingly resilient to heat. For example, some forms of hardened graphite are basically the best rocket nozzle materials available, and can withstand heats far above that of ceramic. Daimond, as was mentioned, is another good example.
"carbon fiber" isn't pure carbon, and is actually part of a polymeric chain, but even it can withstand very high heat. However, as someone else has posted, epoxies generally can't withstand high heat, so that limits the heat capability of the cured composite.
I wouldn't think that CF would be good for apex seal, heat resistant or not, simply because CF is much more brittle than metal.

i was watching discovery on the new scram jet engines not ram, but scram. the material they use to direct the exhaust on those they called "carbon carbon" not so sure what its structural integrity may be or how its made but it is light as carbon fiber and can withstand temps sheet thin more than anything so they claim. just my 2 cents maybe someone els caut that on tv?

oh it can handle the heat. i dunno about the friction part, though.
