Abstract:
An instrumented article (20; 120; 220; 320; 420; 520) includes a ceramic-based substrate (22) and at least one conformal electronic device (24; 524a, 524b) deposited on a surface of the ceramic-based substrate (22). A compliant layer (26) is located between the ceramic-based substrate (22) and the one or more conformal electronic devices (24; 524a, 524b). The compliant layer (26) has a thermal expansion that is intermediate of the thermal expansions of, respectively, the ceramic-based substrate (22) and the one or more conformal electronic devices (24; 524a, 524b).
Abstract:
The present disclosure relates to systems, methods and resins for additive manufacturing. In one embodiment, a method for additive manufacturing of a ceramic structure includes providing a resin including a preceramic polymer and inorganic ceramic filler particles dispersed in the preceramic polymer. The preceramic polymer is configured to convert to a ceramic phase. The method includes functionalizing inorganic ceramic filler particles with a reactive group and applying an energy source to the resin to create at least one layer of the ceramic phase from the resin.
Abstract:
A method for fabricating a ceramic material includes providing a mobilized filler material capable of infiltrating a porous ceramic matrix composite. The mobilized filler material includes at least one of a ceramic material and a free metal. The mobilized filler material is infiltrated into pores of the porous ceramic matrix composite. The mobilized filler material is then immobilized within the pores of the porous ceramic matrix composite.
Abstract:
A method for manufacturing an electronic assembly using direct writing with fabricated foils is provided. The electronic assembly may include one or more foil substrates (210) and one or more elements (220, 222, 224, 226, 228, 230.). The elements may be produced by an additive manufacturing process. Moreover, the elements may be produced in the same plane or out of plain with one or more foil substrates. The elements may also be various structures, including, for example, connectors, electrical components (e.g., a resistor, a capacitor, a switch, and/or the like), and/or any other suitable electrical elements and/or structures.
Abstract:
An erosion resistant and hydrophobic article includes a core that has a first hardness and a surface on the core. The surface includes a plurality of geometric features that have a second, greater hardness. The geometric features define a surface porosity by area percent and a corresponding surface solidity by area percent. The surface includes a ratio of the surface solidity divided by the surface porosity that is 1.8 or greater. The geometric features and the ratio establish the surface to be hydrophobic, and the second, greater hardness and the ratio establish an erosion rate of the surface that is equal to or less than an erosion rate of the core under identical erosion conditions.
