I wouldn't say carbon is tougher than epoxy... Carbon on its own will turn to dust if you look at it wrong.
You can readily find pictures of a Calfee carbon repair but that's not the same as what you want to do.
They have to grind/sand away all the damage and feather the edges to the old finish. The very perimeter of the repair is about what you want to do to the whole frame.
