I have found one on-line vendor offering  UV inhibitor, but the video tutorials that are available do not discuss the need for any added step to protect carbon fiber products. Will the resin used in all three methods of Carbon Fiber fabrication (Resin Infusion, Hand Layup, and Prepreg) have UV inhibitors included in the resin chemistry?

they usually do not. if you want serious UV protection i would recommend an automotive clearcoat on top of your parts.


Thank you. My UAV parts will get rare and short exposure to sun.
