Abstract
A method of making at least one stiffener element includes cutting out two substantially identical elongate flanks from fiber plates, each flank presenting two lateral projections on either side of a central portion. The flanks are superimposed with one another and stitched together along two parallel lines that mark the boundaries between the lateral projections and the central portions. The lateral projections are folded along the lines of stitching to either side of the assembly in order to form flanges.
