The damaged section needs cutting back to the undamaged structure, so if in doubt about heat damage the answer is to cut back I till there is no doubt. This should not be seen as frames, stringers and skin but rather as a whole structure, it can all be joined by bonding.
The quality of such a repair can't be inspected after the fact but has to be inspected on a step by step basis during the lay up.
Usually a sample of the resin and carbon cloth or rovings are laid up into a test piece at the same time as the the job is done, this is then tested to destruction in a lab.
The techniques are quite different from metal repair....... In fact it is far closer to the techniques used for the construction and repair of wooden aircraft.
