I have a carbon steerer tube has a few strands that have come unraveled. What's the best way to "repair" it. Should I just take some epoxy on it, and sand it down? I believe structurally, it's ok. I would just cut it down just below that, but not enough steerer tube left.

epoxy and sand paper. maybe wrap with some electrical tape while it cures to get good compression, maybe it will make too much of a mess though.

Since you appear to already have an aluminum insert for support, I suggest going the J-B Weld route. Make sure the surface is clean and free of contaminants. Apply the J-B Weld and allow it to dry thoroughly. Sand smooth and enjoy the ride! BTW, at least one carbon fork manufacturer actually recommended using J-B Weld for dressing small frayed areas at the top of their steerer tubes.

Good idea. Maybe some painters tape.

JB Weld, the liquid duct tape. Thanks for the input.

that is not even that bad, I don't think its structural either.

I recently cut a steerer on a brand new fork and ****ed it up. Luckily I measured it wrong and cut it way too high lol, cut it again and did a good job this time.
