Depending upon if tney are making carbon fibres or graphite fibres, the temps vary a bit. Up to 3500 degrees C to make the fibres.

Most epoxies have issues starting at a few hundred degrees. Phenolis, Bismalides, and other systems withstand more heat, but carbon based resin systems are one of the most heat tolerant.

Not freak you out, when a composite part on an aircraft takes a lightning strike, the resin is essentially imediately evaporated out of the carbon fibres. After that it is ugly. Done correctly, LSP or lightning strike protection repairs are critical to the aircrafts longevity.
