im not sure foam will be happening anytime soon. foam is basicilly a bubble with gas traped inside.
tho for bigger airplanes, it might work. 0.7 mm thick wings are heaiver than, say 1mm depron, but when you scale it up, you could do stuff like honeycomb wing ribs for a 48 inch WS. then the weigh is not as big a deal.
in not sure of the strength vs CF or plywood, but it does have the advantage of bending. any airliner will have wing flex designed in to it. i would think it helps dampen out the changes in motion.
its an intresting medium that has not been done yet. you get the flexablity of foam, with the strength of thin ply wood, but you have much finer control.
