Carbon fiber strands are held in place by polyester resin (like boats are made of), think it would start to catch fire and melt right at about 550F.

Yeah ... Carbon Fiber melts pretty quick bud ... Friend of mine had a complete carbon fiber body for his dragster ... Engine caught fire and then the whole front/driver side of the car. The doors melted and fused shut and they had to pull him out of the other side.

well, IMO, i would only use carbon fiber for looks. Dont want it for lightness or whatever. I know what apex seals are good.. and thats stock seals. so i wouldnt have to worry about that.

He probably means Racing Beat's Carbon Apex Seals. That is something completely diffrent. Those carbon seals are not used too much anymore. They are meant for racing applications which do NOT involve turbos only normally aspirated engines and they wear out VERY FAST (Never been worth buying those pieces of ****). Most racing engines nowdays are running on factory seals and/or Iannetti Ceramic Apex Seals ($200 plus EACH seal) about $1,200 to $1,500 for seals only.

Resins that can handle the heat are available, but the wear would be a problem. They would wear out in 5-10K miles at most.

How about carbon fullerines?

I don't expect half of you to remember that thread in the lounge.

Then every time the car detonated, you would have good apex seals and a crushed rotor or housing. I would rather replace apex seals than more expensive engine parts.

HEY MYKL! Good call. Did you see the article on IBM's devolpment of nanotechnology. It talked about usefull carbon fullerene applications. This may not be too far off!
