A method for manufacturing a wing box (10) for aircraft, comprising the steps of: a1) arranging, on a curing surface (22), a first panel (12a), made of a composite material, comprising a skin (16) having a first side (16') and a plurality of stringers (18) that extend parallel to a longitudinal direction (x); b) alternately arranging, on said first side (16') of the first panel (12a) along a transverse direction (y), a rib (14), made of non-polymerized composite material - each rib (14) comprising a plate (15), a first pair of flanges (15a) and a second pair of flanges (15b) arranged at opposite ends of said plate (15) - by placing the first pair of flanges (15a) on said first side (16') of the first panel (12a), and a tool (24) - each tool (24) comprising a central part (24a), a bottom part (24b) and a top part (24c), wherein the central part (24a) of each tool (24) is interposed between said bottom part (24b) and said top part (24c) and may be extracted in a transverse direction (y) - between each pair of consecutive ribs (14) and in contact with both; c) arranging a second panel (12b), made of a composite material, comprising a skin (16), having a first side (16'), and a plurality of stringers (18) that extend along a longitudinal direction (x), by putting said second panel (12b) in contact with the second pair of flanges (15b) of each rib (14); d) pulling out the central part (24a) of each tool (24) along the transverse direction (y) and subsequently removing the top part (24c) and the bottom part (24b) of each tool (24); and e) subjecting the first panel (12a), the second panel (12b), and each rib (14) to a curing process in autoclave with vacuum bag, according to a specific pressure and temperature cycle, for curing the non-polymerized components.
