And this is why good peel ply finish is a better binding surface than ground or sanded composite: a large part of the area of a sanded part will be unfinished glass.Fiberglass is often coated with a finish (e.g. silane) to improve the bond strength.
I'm not sure if that is true for carbon fiber; I haven't heard any mention of it needing a finish to properly adhere to epoxy.
