Carbon fiber is not only used for weight savings, but strength too. I have a carbon fiber panel in my RV-10 and I don't believe that plywood would be strong enough to support my panel layout unless it was 1/2" thick or more. (too many holes) I would install an aluminum panel if carbon fiber wasn't an option.
In my particular case, the aluminum fuselage is primed AKZO epoxy primer and top coated. The carbon fiber is incapsulated in epoxy resin, then primed, and top coat applied. It would take quite a bit of rubbing to wear through all those layers with a panel that is rigidly installed to the fuselage (movement is severely restricted)
If this really keeps you up late at night, put it on your conditional or annual inspection checklist.
