A method to manufacture a structural component in composite material reinforced with stiffening stringers and comprising a skin and plurality of stringers having a hollow section fixed to said skin. The method comprising: a) laminating a plurality of first layers of composite material onto an external surface of a cure tool, b) laminating pluralities of second layers of composite material on longitudinal hollow expandable inserts, c) positioning each reinforcing element on a face of a second skin, d) holding each reinforcing element on the face of the second skin; e) housing the tool, skin and reinforcing elements inside a vacuum bag; and f) compacting together the first layers forming the skin with the second layers forming the stringers; g) housing skin and reinforcing elements in a further vacuum bag; and h) sealing the further vacuum bag; and i) applying preset temperature and pressure to the outside of the vacuum chamber.
