Carbon fiber temperature limit?
I am considering using carbon fiber in an application that is exposed to high temperatures. Does anyone know what the limit is? I know it is cured at high temperatures, but what about long-term exposure. It has to retain its structural integrity also.

Overly broad question, it seems.
relevant expertise.. read the product data sheets
supplied by the [catalyst activated epoxy] Resin's Manufacturer.
The vendor of these materials may be able to guide the selection
of the materials for your project.

FWIW: Formula One cars use carbon-carbon brake rotors. Carbon fiber embedded in a carbon matrix. They hit 2200° F repeatedly: https://www.f1technical.net/articles/2
Very pricey aerospace grade stuff. Is that what you want?

Carbon at sea level pressure melts at 6332deg.F. so you might want to keep it cooler than that.

I've worked with carbon fiber for many years in yacht building applications and while working for a defense industry contractor. The carbon fibor will take planty of heat but the epoxy resin of typical composite laminates begins to soften around 200 degrees F. There may well be resins that work at higher heat. You need to contact resin manufacturers for specific info on your application.

One warning: In stress tests, the CF aircraft would withstand several times as many cycles as aluminum before failure. But the alloy gave some warning, with cracks and whatnot. The carbon lasted far longer, but then essentially disintegrated all at once.

For those concerned about cold temps: they've been using carbon fiber for the antenna masts on deep space probes since the first Voyager mission in the late 1970s.
