Abstract
A pair of specially reinforced skin-spar joints in combination with a honeycomb core are used to build up a wing spar for a composite airplane wing. A series of contoured mandrels with a covering of fuel resistant material and a wrapped reinforced plastic are aligned one above the other. The wing spar materials are placed between the mandrels, honeycomb core is located alongside as well as wing skins to form a wing buildup. The buildup is placed in a mold, pressure applied to each mandrel forcing all the parts together, and the buildup heated to cure the resins and form a composite wing structure.
