I'm not sure what adding glass on top of the hinge would add structurally because the key securing means are the "flox rivets".  After the hinge, the cloth would immediately encounter a 90 curve so that no effective tensile strength would be obtained.  If anyone knows better, I'm all ears!

I think you should put a 2 bid layer on top of the hinge to give the flox ritets something strong to stick to. The fiber is much stronger than the epoxy/flox. The forces would tend to pull the fibers through the hole. So even though it is a 90 curve, tensile strength still applies. Have you ever removed a rivot by carefully grinding the head down paper thin, and then breaking it out. This is what is going to happen to your epoxy flox rivots.

About galvanic issues with carbon, you have to have a media such as water to make this happen. If you seal the rivots in the carbon fiber with epoxy, you will not get galvanic action. What happens is an insulating oxide layer will form between the rivot and the carbon fiber. A very thin oxide layer that doesn't cause any harm. As soon as this oxide layer forms, galvanic action will stop unless something like water washes the oxide layer out. Since everything is sealed, galvanic action will never go beyond the time it takes for the resin to cure. This short amount of time would be insignificant.
