Aspects disclosed herein include graphite and hexagonal boron nitride bimaterials, methods of making these bimaterials, and electric propulsion devices or thrusters with these bimaterials. Aspects disclosed herein include electric propulsion devices comprising: at least one portion comprising or formed of a monolithic bimaterial; wherein the monolithic bimaterial comprises a graphite material and a hexagonal boron nitride material; and wherein the graphite material and hexagonal boron nitride material are monolithically integrated in the bimaterial.

Graphite/hexagonal boron nitride bimaterials for electric propulsion

Elements formed from magnetic materials and their methods of manufacture are presented. Magnetic materials include a magnetic alloy material, such as, for example, an Fe-Co alloy material (e.g., the Fe-Co-V alloy Hiperco-50(R)). The magnetic alloy materials may comprise a powdered material suitable for use in additive manufacturing techniques, such as, for example direct energy deposition or laser powder bed fusion. Manufacturing techniques include the use of variable deposition time and energy to control the magnetic and structural properties of the materials by altering the microstructure and residual stresses within the material. Manufacturing techniques also include post deposition processing, such as, for example, machining and heat treating. Heat treating may include a multi-step process during which the material is heated, held and then cooled in a series of controlled steps such that a specific history of stored internal energy is created within the material. Magnetic elements may include, for example, motors, generators, solenoids and swtiches, sensors, transformers, and hall thrusters, among other elements.

Magnetic elements and methods for the additive manufacture thereof

Systems and methods of additively manufacturing multi-material electromagnetic shields are described. Additive manufacturing processes use co-deposition to incorporate multiple materials and/or microstructures selected to achieve specified shield magnetic properties. Geometrically complex shields can be manufactured with alternating shielding materials optimized for the end use application. The microstructures of the printed shields can be tuned by optimizing the print parameters.

Elements formed from magnetic materials and their methods of manufacture are presented. Magnetic materials include a magnetic alloy material, such as, for example, an Fe&#x2014;Co alloy material (e.g., the Fe&#x2014;Co&#x2014;V alloy Hiperco-50&#xae;). The magnetic alloy materials may comprise a powdered material suitable for use in additive manufacturing techniques, such as, for example direct energy deposition or laser powder bed fusion. Manufacturing techniques include the use of variable deposition time and energy to control the magnetic and structural properties of the materials by altering the microstructure and residual stresses within the material.

Heat treating may include a multi-step process during which the material is heated, held and then cooled in a series of controlled steps such that a specific history of stored internal energy is created within the material. Magnetic elements may include, for example, motors, generators, solenoids and switches, sensors, transformers, and hall thrusters, among other elements.

Printed textiles and related manufacturing methods are provided. Textile materials can include laced mesh fabrics made of rigid components. The laced mesh structures are designed for space applications, including but not limited to adaptive and foldable reflectors, capturing systems, debris and micrometeorite shielding, shading systems, sample capturing, and various other applications. The laced mesh structures are used in the generation of tailored, unique radio-frequency antennas and receivers that allow for active tuning/receiving capabilities. The tailored structure can also include multi-material systems mixing dielectric and conductive layers for enhanced, tunable transmission. Laced mesh structures can also be used for enhanced thermal control of components, with the ability to tailor thermal conductivity and emissivity, to create thermal engineered components via the generation of localized or global thermal response (e.g. zone thermal control).
