摘要： This invention provides resin formulations which may be used for 3D printing and pyrolyzing to produce a ceramic matrix composite. The resin formulations contain a solid-phase filler, to provide high thermal stability and mechanical strength (e.g., fracture toughness) in the final ceramic material. The invention provides direct, free-form 3D printing of a preceramic polymer loaded with a solid-phase filler, followed by converting the preceramic polymer to a 3D-printed ceramic matrix composite with potentially complex 3D shapes or in the form of large parts. Other variations provide active solid-phase functional additives as solid-phase fillers, to perform or enhance at least one chemical, physical, mechanical, or electrical function within the ceramic structure as it is being formed as well as in the final structure. Solid-phase functional additives actively improve the final ceramic structure through one or more changes actively induced by the additives during pyrolysis or other thermal treatment.

摘要： A thin-walled metal part, and a method to fabricate such a part out of various alloys. A plurality of layers are formed, each of the layers being formed on a polymer template or on a previously formed layer. A homogenizing heat treatment is used to cause chemical elements in the layers to interdiffuse, to form a single continuous layer with a substantially uniform alloy composition.

摘要： Some variations provide a process for fabricating a ceramic structure, the process comprising: producing a plurality of preceramic polymer parts; chemically, physically, and/or thermally joining the preceramic polymer parts together, to generate a preceramic polymer structure; thermally treating the preceramic polymer structure, to generate a ceramic structure; and recovering the ceramic structure. The process may employ additive manufacturing, subtractive manufacturing, casting, or a combination thereof. A composite overwrap may be applied to the preceramic polymer structure prior to pyrolysis, and the composite overwrap also pyrolyzes to a ceramic composite and is a part of the final ceramic structure. The ceramic structure may be silicon oxycarbide, silicon carbide, silicon nitride, silicon oxynitride, silicon carbonitride, silicon boronitride, silicon boron carbonitride, or boron nitride, for example. The ceramic structure may have at least one dimension of 1 meter or greater, and may be a fully integrated ceramic object with no seams.

摘要： Described is a micro-lattice damping material and a method for repeatable energy absorption. The micro-lattice damping material is a cellular material formed of a three-dimensional interconnected network of hollow tubes. This material is operable to provide high damping, specifically acoustic, vibration or shock damping, by utilizing the energy absorption mechanism of hollow tube buckling, which is rendered repeatable by the micro-lattice architecture.

摘要： A lightweight sandwich panel structure with a complex shape and curvature, and a method to fabricate such a panel out of high temperature alloys. Embodiments of a micro-truss core structure that offer high specific strength and stiffness while allowing for curvature, and methods for depositing multiple layers of metals that can be interdiffused into complex alloys, are provided. A core of a panel may be fabricated from a polymer template, which may be shaped, e.g., curved, and coated with metal layers, which may then be heat treated to cause the layers of metal to interdiffuse, to form an alloy.

摘要： A new battery structure as disclosed allows convective flow of electrolyte through three-dimensional structured electrodes. Hierarchical battery structure design enables three-dimensional metal structures with fluid transport capabilities. Some variations provide a lithium-ion battery system with convective electrolyte flow, comprising: a positive electrode comprising a lithium-containing electrode material and a conductive network with hollow liquid-transport conduits; a negative electrode comprising a lithium-containing electrode material in the conductive network; a separator that electronically isolates the positive and negative electrodes; and a liquid electrolyte contained within the hollow liquid-transport conduits of the conductive network. The hollow liquid-transport conduits serve as structural members, and the walls of these conduits serve as current collectors. The conductive networks may include a micro-lattice structure with a cellular material formed of hollow tubes. Performance and thermal management of lithium-ion batteries (and other types of batteries) can be improved.
