I'm fairly certain Carbon Fiber conducts, I would not use that in a battery case.

You surprise me. Carbon is certainly heat-resistant to quite a good extent, but it does burn. So does resin, which is usually what's used to bind the carbon fibres together, so how do they do it?

Thanks for that video hoppy. I guess exhaust gas shouldn't be as hot as an oxy-acetylene torch (though my OS90FS used to regularly burn through it's flexible metal header ), but it still doesn't explain how cf exhaust pipes can presumably survive years of that type of treatment without deforming.

The gypsum? core did provide some protection against burn through.
If you're worried about the paper burning...

explains how to fire proof cloth and other flammable fibrous materials.
Recommended by fire departments. Just water, borax and boric acid.
