Composite transverse wing rib and apparatus for producing flat cellular-ribbed structure thereof

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 t...

Beschreibung
Zusammenfassung:	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. An apparatus for making a wing rib comprises a base having a flat surface on which are mounted a plurality of oppositely angled rod-shaped members each defining a channel therein such that a system of intersecting channels are formed for receiving intersecting layers of strips of composite material. The apparatus also includes pins mounted on the outer periphery of the base, about which the strips of composite material are wrapped to form the projections on the cellular-ribbed structure.
