Abstract
A method of constructing a carbon fiber composite wing in which upper and lower skins are bonded to a pre-assembled rib 15 and spar 16 framework, thus obviating the need for metal fasteners and hence cutting down assembly time. In one embodiment a novel cleat 17 of cruciform cross-section replaces the four cleats conventionally used for bolting the ribs 15 and spars 16 together. Holes 22 drilled in either end of the cleats serve as jig location points during framework assembly and anti-peel fastener holes after the skins have been bonded.
