A method for manufacturing a wing box for aircraft comprises the steps of arranging, on a curing surface, a first panel of composite material, alternately arranging, on the first panel, along a transverse direction, a rib of non-polymerized composite material and a tool comprising a central part, a bottom part and a top part, wherein the central part of each tool is interposed between said bottom part and the top part and may be extracted in a transverse direction, arranging a second panel of composite material by putting said second panel in contact with the flanges of each rib, pulling out the central part of each tool along the transverse direction and removing the top part and the bottom part of each tool, and subjecting the first panel, the second panel, and each rib to a curing process in autoclave with vacuum bag.
