<p>A pair of specially reinforced skin-spar joints (10) in combination with a honeycomb core (46) are used to build up a wing spar (44) for a composite airplane wing. A series of contoured mandrels (82) 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 (50) is located alongside as well as wing skins (48) 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. </p> |
