@Rebel_without_Clause, RC aircraft wings are normally built up out of ribs and spars, then covered with a very lightweight covering (or folded up out of foamboard and hot-glued!) rather than being laminated from composite materials… The wing loading tends to be pretty light at typical RC speeds and maneuvers.
However, it is pretty common to see people using CF wing ribs and CF tubing for spars and other structural members (e.g. tail booms). Maybe if you tell us a bit about your use case, we can help you develop a plan.
