Greetings guys.... There has been a lot of discussion on this reflector about how and where one should attach carbon onto spars to make them effective. If I were building a woody that required some additional strength to a wing I would put carbon on the bottoms of both upper and lower spars. The reasons are this, first, carbon fiber is stronger under tension and not compression. Second I would be concerned of the carbon delaminating if it was on the upper surface of a spar. The other thing that I'd consider doing is adding the carbon to the spars prior to assembly. I'd even go as far as using a vacuum bag to apply enough consistent pressure along the entire surface of the spar & carbon. Just throwing my 2 cents in....
