Abstract
A method of manufacturing an aircraft component, the component comprising a pair of covers joined by a pair of spars. The covers and spars form a closed box structure with four corners, each corner providing a transition between one of the covers and one of the spars. The method comprises: laying up a laminated sheet of fiber plies; and after the sheet has been laid up, folding the sheet to form the four corners and then joining the sheet to itself to provide the closed box structure.
