To work on composites its a 2 week Q course at the FRP School at Wittering, then you can be Auth'd to do the job.If you can do a fibreglass repair you can probably do a carbon fibre repair, the process is similar, with having to taper sand the repair area to ensure that you get down to the bottom of the damage and give sufficient original material showing on each of the plies so that the new plies you install adhere to the original material, following the direction of the original plies, after which it is simply a case of choosing the correct menu on the hot bond machine and following the lay up instructions with regard to the vacuum and temp of the repair for the time specified all this info can be gleaned from either the SRM or the AMM. Of course one should have some training to ensure that what you read in the manual is what you do in practice.
As I said before, cleanliness is imperative and taper sanding is not always easy as it is possible to sand through two or more layers of material thinking it is only one layer. Some carbon fibre skins may have as many as nine or more plies, each of them offset from the previous and following one by a specified number of degrees and new plies must be installed in the same direction as the one it is replacing to provide original strength to the repair area.
Lots of fun.
