A method of making a wing for an aerospace vehicle includes forming a frame member defining opposing perpendicular legs being spaced by an interconnecting member. A plurality of ribs is interconnected along the frame member at spaced locations forming an internal wing structure. Each of the ribs define an upper rib surface and a lower rib surface. A composite upper skin and lower skin are formed as a continuous sheet by way of a pultrusion process defining a shape that is complimentary to the plurality of ribs. The upper skin is secured to the upper surface defined by the plurality of ribs and the lower skin is secured to the lower surface of the plurality of ribs forming the aerospace wing.
