Patent ID: 7510757

Claim:
A cellular composite structure, comprising: a grid including a plurality of intersecting ribs arranged in a plurality of rib groups, the ribs of each group oriented in a non-crossing pattern with respect to each other and angularly oriented with respect to the ribs of the other groups; a plurality of rib intersections defining a plurality of rib segments; a plurality of contiguous rib walls each configured as a closed geometric shape, each of the contiguous rib walls having a selected group of the rib segments sharing selected ones of the rib intersections operable to define the closed geometric shape, and each of the contiguous walls operably defining one of a plurality of composite structure cavities; and a cap member slidably receivable within each of the cavities, each cap member including at least first, second, and third layers of material, the layers together defining an end wall, each of the first, second, and third layers further including a riser wall oriented at a predetermined angle with respect to the end wall, each riser wall oriented parallel to and substantially in sliding contact with an individual one of the rib segments of the selected group of the rib segments; wherein the cap members and the plurality of intersecting ribs are co-cured to adhesively bond the riser walls and the rib segments to create the cellular composite structure.
