The invention relates to a method of making at least one stiffener element, the method comprising steps of: cutting out two substantially identical elongate flanks (2, 4) from fiber plates, each flank presenting two lateral projections (10, 14) on either side of a central portion (6); superposing the flanks (2, 4) and stitching them together along two parallel lines (8, 12) that mark the boundaries between the lateral projections and the central portions; and folding the lateral projections (10, 14) along the lines of stitching to either side of the assembly as formed in this way in order to form flanges (22, 24).
