How heat resistant is carbon fiber? Options

[dabazied]

Just wondering how heat resistant it is, meaning real carbon fiber or even like if you go through the process of wrapping yourself, like with the hardener and the cloth and all that stuff. Just curious.

It depends, the visual stuff you see on most cars is not very heat resistant.
But there are pieces that replace intake manifolds, heat shields, air tubes, ect.
It just depends what materials are used to make the piece.
Some resins used in the fabrication are specifically designed for high heat use and some are not

Ok, so If I was doing my own wrapping and stuff like that, there are some resins I can get that are for high temp. Sounds good. Thanks man. How you been?

[freddy121389]

yea but with those high heat resistance resins wouldn't it be hard to mold your own cf stuff considering that you need a lot of heat to mold them?

That carbon fiber stuff on cars just for looks its nothing compared to the stuff they use on Stealth bombers or the jet going to the Moon. If you wrap you headers on that stuff using the resin and carbon fiber, Its going to catch on fire. Use the exhaust wraps.

the cf i've dealt with is not very heat resistant. i've had 3 carbon fiber engine covers from trd and they all turn yellow/brown after a while. i thought it was a unique defect but after a while i just put them on for show. could be bad quality cf being used by trd's third party? i dunno.

I've been good, thanks for asking
You can get high temp resins, but 99.9% of them aren't going to cure @ room temp or something that a typical home grown is able to do.

I highly highly recommend getting on http://www.compositeforum.werksberg.com/ and doing some research into it.

Thanks for the site man, I'll be doin a lot of research on this(got a little project idea I need to do research on, and it's not just what you think with the headers and exhaust piping).

Playr, you still able to get those cf coupe trunk lids?

[RabidTRD]

They sell exhaust heat shields to protect your bumper for quite a bit... Depends on how the cf is treated

First off real carbon fiber is not available for DIY to my knowledge. Its ninety percent resin and only ten percent carbon fiber matting. The resin itself is so hard when dried that ninety percent of a f1 chassis or airplane fuselage is resin. I was told by a carbon fiber bicycle manuacturer rep that if it gets on anything including your hands you are SOL.

If carbon fiber was tolerant of heat we would see carbon fiber blocks(sleeved of course), pistons, crankshafts and rods on F1 engines by now. Unfourtunately I dont think it can handle the temperature water boils at.

Im sure the temps vary depending on the resin. But most peak tolerances I have seen are around 180F

F1 brake discs are carbon fibre and opperate at 1200degC

true but those have a different structure (obviously) than regular CF sheet.

If you go with that sort of compound ( carbon fibre-reinforced silicon carbide ) you could cast whatever you want, and it would be heat tolerant, just not reliably strong
