Patent application numberDescriptionPublished
20080220177Reliant Thermal Barrier Coating System and Related Methods and Apparatus of Making the Same - A method and apparatus for forming a thermal barrier coating system (09-11-2008
20080226870Multifunctional periodic cellular solids and the method of making thereof - 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: (09-18-2008
20090274865CELLULAR LATTICE STRUCTURES WITH MULTIPLICITY OF CELL SIZES AND RELATED METHOD OF USE - A sandwich panel core that may be comprised of a lattice structure utilizing a network of hierarchical trusses, synergistically arranged, to provide support and other functionalities disclosed herein. Since this design results in a generally hollow core, the resulting structure maintains a low weight while providing high specific stiffness and strength. Sandwich panels are used in a variety of applications including sea, land, and air transportation, ballistics, blast impulse mitigation, impact mitigation, thermal transfer, ballistics, load bearing, multifunctional structures, armors, construction materials, and containers, to name a few.11-05-2009
20090282773Manufacture of Lattice Truss Structures from Monolithic Materials - Methods and systems to manufacture lattice-based sandwich structures from monolithic material. Such methods and systems eliminate the bonding process which is conventionally used to join lattice based truss cores to facesheets to form sandwich structures. This bonded interface is a key mode of failure for sandwich structures which are subjected to shear or bending loads because the nodes transfer forces from the face sheets to the core members while the topology for a given core relative density dictates the load carrying capacity (assuming adequate node-bond strength exists). An aspect comprises a core and related structures that provide very low density, good crush resistance and high in-plane shear resistance. An aspect of the truss structures may include sandwich panel cores and lattice truss topology that may be designed to efficiently support panel bending loads while maintaining an open topology that facilitates multifunctional applications.11-19-2009
20090286100Manufacture of Lattice Truss Structures from Monolithic Materials - Methods and systems to manufacture bonded corrugation truss-based structures. This allows the ability to change the dimensions of the individual structural features of the corrugations, i.e. thickness of the core, face sheet thickness, relative density of the core, and the alloys. The nodal design which provides ideal stress/strain distribution for in-plane and out-off plane loading. The node has a curved/smooth triple point intersection which in turn can provide best load transfer interface with high integrity/toughness. The bonded corrugation truss based structure can be continuous to any length only limited by the volume of the extrusion billet and the press capacity. An aspect of the bonded corrugation structures may include friction stir welding of the face sheets or any fusion welding of panels with edge members for strengthening allows fabrication of panels of any width and length. Bonding panels enables the fabrication of structures of any width.11-19-2009
20100236759Heat-Managing Composite Structures - Light-weight, heat-managing structures feature open-cell lattice, honeycomb, and/or corrugated (prismatic) arrangements in their substructures, combined with heat pipe/heat plate arrangements for managing heat to which the structures are subjected. The structures are well suited to aerospace applications and may be employed in the leading edge of wings or other airfoil-shaped components; gas turbine engine components; rocket nozzles; and other high-heat, high-stress environments.09-23-2010
20110042512Method and Apparatus for Jet Blast Deflection - Methods and apparatuses for passive jet blast deflection or the like. Use of the passive jet blast deflector permits the efficient dispersal of a fast moving local heat source into the environment through passive means while providing a high strength structure. The jet blast deflector system may include a first plate, a second plate, and a cellular core disposed between them adapted to allow cooling ambient air to flow through the cellular core, wherein the first plate, second plate, and core are all seamlessly coupled heat pipes that form a single vapor core to facilitate the spreading and even storing of thermal energy. An ejector plate may be attached to the top of the second plate to create a low pressure zone as the heat source passes over it, thereby pulling the ambient air through the cellular core, facilitating the removal the thermal energy from the system.02-24-2011
20110107904Synergistically-Layered Armor Systems and Methods for Producing Layers Thereof - The armor system according to the present invention also exploits synergistic multi-layering to provide different properties as a function of depth within a sandwich panel. Various embodiments of the invention include a combination of composite sandwich topology concepts with hard, strong materials to provide structures that (i) efficiently support static and fatigue loads, (ii) mitigate the blast pressure transmitted to a system that they protect, (iii) provides very effective resistance to projectile penetration, and (iv) minimizes shock (stress wave) propagation within the multi-layered armor sandwich structure. By using small pieces of highly constrained ceramic, the concept has significant multi-hit potential.05-12-2011
