What temperature do you think is required?
What will you do about the chamber? If you're adding suspenders to an a safe barrel profile, yet want to protect against catastrophic failure, then the zone of greatest pressure should also be covered.
There's another aspect about what you're trying to accomplish that requires consideration, and that is the failure mode of carbon (or glass) fibers. These materials fail catastrophically by sudden fracture, so they should not be worked to strains anywhere near failure strain. Ductile metals fail gracefully by yielding.
So, none of that answers your basic question. If you consider high temperature something over about 180 to 200 degrees, then oven curing is necessary, and most likely a post cure to raise the glass transition temperature of the resin will be required. When curing steel plus carbon/epoxy together at elevated temperatures, the difference in the coefficients of thermal expansion must be considered if the parts are to work together correctly.
I can add more, later, I have a meeting.
