I'm actually quite suprised about the "OMG this is new KILL IT WITH FIRE" responses so far.

If CFRP repairs anything like fibre glass, patching shouldn't be much of an issue. Fibre glass repairs end up just as strong as the original.

I just hope that in potential military transports to be built after this, that they make damned sure they are on the money with the repairability. Yes, the vaccuum bag and oven is as good as it gets for composite repairs, I was not aware it was portable enough to be used in an assembeld structure though. You learn something new every day. Bbut even if it is there will be places on any airframe where you cant get it to. Also I'm not convinced that any repair on a composite given the nature of its structure. 8+ axes of fibresin any composite, orientated specifically to carry the stresses of the component in that specific point. Try to put a patch in it, you need to make damned sure the fibres are in the right direction, and bonded to the fibres in the origional part. If theyre not lined up or connected, you just have the matrix that carries almost no stress at all. Composites are only strong in the directions we design them to be, unlike metals their material properties arent the same in every direction.

The (no doubt thick) sandwich absorbs a lot of energy too, often preventing damage to the inner skin.
