An aircraft wing 201 has a framework supporting a skin 60 with a spar (fig.1,80) extending the length of the wing between a root end 20 and a tip end 30 of the wing, a number of ribs (fig.1,70) extending chordwise between a leading edge 40 and a trailing edge 50-2 of the wing, and a number of stringers 10a,10b,11a-11c attached to the skin. A main stringer 11c extends the length of the wing from nearer the root to nearer the tip, and an auxiliary stringer 10b, extends non-parallel to the first stringer, with a portion near the tip end of the first stringer. The auxiliary stringer may extend along the tailing edge of the wing and may be formed from a number of parts so that it is non-linear or curved to conform with the shape of the trailing edge. Also claimed is a main stringer with at least one branching portion extending at an angle from the main stringer, towards the wing root. The main stringer may have a number of equidistantly spaced, parallel, branches, and be formed from a stack of carbon fibre reinforced polymer (CFRP) plies (fig.3,15a-c), with each branch extending from a respective ply.
