Abstract: A vented honeycomb structure with a plurality of honeycomb cells arranged in a hierarchical order and having a plurality of truss walls, each truss wall including a plurality of members. The vented honeycomb structure is fabricated by joining a plurality of sheets of trusses using any one of an expansion, a corrugation, and a slotting process. Fabrication can also occur by deposition, casting, additive, extrusion, or aligning and joining methods. The honeycomb cells, truss walls, truss wall openings, and truss wall members can be functionally graded.

Abstract: A cellular material that can provide a unique combination of properties and characteristics for a variety of applications requiring a cellular solid that possesses one or more of the following characteristics: (1) efficient load support in one or more directions, (2) excellent mechanical impact energy absorption and vibration suppression potential, (3) high convection heat transfer throughout, (4) low pumping requirements for fluid throughput, for example in a second direction orthogonal to one or more load-bearing directions, (5) a substantially linear dependence of the Young's and shear moduli along with the tensile, compressive and shear yield strengths upon relative density (6) a potentially inexpensive textile-based synthetic approach, (7) excellent filtration potential, (8) a high surface area to volume ratio for enhanced activity as a catalyst or catalyst support (9) interconnected, open porosity for device storage, biological tissue in-growth or other functionalities requiring open space, and (10) ext

Abstract: Methods of making truss-based periodic cellular solids that have improved structural properties and multifunctional design. Many materials (metals, ceramics, glasses, polymers, composites and even semiconductors) can be shaped into cellular, truss-like architectures with open, closed or mixed types of porosity and then very uniformly arranged in controlled, three-dimensional space-filling arrays. The truss-like elements do not necessarily have a constant cross-section, nor are they necessarily straight or solid throughout (they could be hollow). Their cross sections can be circular, square, triangular, I-beam or other shapes of interest depending on multifunctional needs. When bonded together by solid state, liquid phase, pressing or other methods at points of contact, a cellular structure of highly repeatable cell geometry and few imperfections results.
