  • Composite transverse wing rib and apparatus for producing flat cellular-ribbed structure thereof
    Patent number: 5993941
    Abstract: A composite transverse wing rib shaped as a multi-layered flat panel comprises a cellular-ribbed structure of intersecting rectlinear ribs whose lengthwise directions are angled in opposite directions at oblique angles to a longitudinal dimension of the wing rib. The ribs have widthwise directions that extend between opposite side surfaces of the cellular-ribbed structure. The cellular-ribbed structure includes projections having flat faces arranged on an outer frame of the structure. The wing rib also includes other layers overlying opposite side surfaces of the cellular-ribbed structure and the projections. The outer layers comprise a net of intersecting small composite belts oriented along the oppositely angled directions of the rectilinear ribs and intersecting at the cross intersections of the rectlinear ribs. The cellular-ribbed structure and outer layers are formed of high-module yarns bound by a polymer binder.
