rubberlegs said:Fiberglass is quite flexible in bending. Check out the 747 variable camber krueger flaps, where the fiberglass is flat when stowed for high speed flight, and bent for takeoff and landing:. These things bend for 20 years and 40,000 flights, twice a flight with no fatigue problems. However on a camper it may be a shear situation and perhaps the fiberglass, if stiff, could be worse than strips of aluminum. Interesting thought.
Wow! Cool video...80,000 times they are cycled without replacement, amazing...one other small point, when retracted they are not in direct UV...hopefully !!...and as you say fiberglasses are not all created equal...
