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....
