see my last post.......Phenolic sheet is essentially a fiberglass (could be
other base materials like cotton or canvas, paper ect) panel as used in most
if not all new gliders..you could use the canvas or cotton based phenolic
sheet as well....it is not as sturdy as the fibergass sheet but ceratinly,
if used in the right panel types would be strong enough (you'd want a bit
more "meat" between the instrument openings) and I have used this material
also for more basic panels like in vintage ships and this type phenolic does
break more cleanly....the material is quite inexpensive and you could try
some samples for yourself. Since many gliders are already experimental as
was the one I believe that started this thread, it could be used without
having to be a certified part.
