Abstract
A method of forming an airplane wing and a resulting article of manufacture where a wing structural member is provided which is composed of a plastic foam layer sandwiched between opposing paper sheets. A substantial portion of one of the paper sheets is removed from the plastic foam through application of water to pulpify one of the paper sheets and then stripping such from the plastic foam layer. The resulting structural member is then formed into a predetermined contour after compression of the foam layer in the leading edge region of the wing. Rib elements may be secured to an internal surface of the wing and the trailing edges are tapered prior to securement of the trailing wing edges throughout the wing extended length.
