<p>A method of manufacturing a rib-stiffened shell 50 for a structure, wherein the rib-stiffened shell 50 comprises an outer skin 56 supported by a plurality of fiber ribs 54, the fiber ribs 54 comprising thickened strips of substantially unidirectional fiber, and wherein the fiber ribs 54 comprise a crisscrossing pattern that includes a plurality of junctions, the junctions 58 comprising an intersection of two or more of the fiber ribs 54, the method comprising the steps of: configuring a convex mold 70, the shape of which corresponds to the contour of the outer skin 56 of the structure; configuring a plurality of grooves 74 in the convex surface of the convex mold 70 that correspond to the pattern of the fiber ribs 54; laying up unidirectional fiber in the grooves 74 of the convex mold 70; and applying the outer skin 56 over the convex surface of the convex mold 70.</p> |
