I'm probably not the right one to know this but I do not think you can repair carbon fiber, not with epoxy and duct tape
There could be more damage than meets the eye, that is you "fix" what's visible and underlying structural damage that could fail. My bikes are steel but I have CF wheels on my road bike (Rolf). If I suspected any damage to them whether visible or I was in a crash I would take them to my shop and have them checked.
When in doubt throw the carbon out. My vote is you should shop for new wheels.
