STOP PRESS - It is the Al dropout that is bent and it can be unbent, thankfully.

Al is not good once elastic limit has been exceeded. Unlike steel. But I
guess that since it is an insert, rather than an integral piece of frame
it is not so critical.

The carbon bits of the frame end at the wheel dropouts which are aluminium. It is only the rear mech hanger bit which is bent so it can be gently eased back which is good news.

Here is a Carbon frame that has been in a real crash - as can be seen, they don't really bend as such.

Shortly after 9/11 a sub contractor tried to repair a carbon wing or tail section like it was a surfboard ding. Apparently composite materials in modern commercial air craft is a little more complicated than that. The air liner crashed in NY City killing all on board. The NTSB & FAA were really good telling everyone it wasn't terrorism so don't worry about it.

If you do the same thing with a damaged carbon bike frame, be careful when you first try it out. Don't start off pegging curbs, pot holes, RR tracks, etc.
