Abstract: A system for synthesizing carbon nanotubes (CNT) on a fiber material includes a surface treatment system adapted to modify the surface of the fiber material to receive a barrier coating upon which carbon nanotubes are to be grown, a barrier coating application system downstream of the surface treatment system adapted to apply the barrier coating to the treated fiber material surface, and a barrier coating curing system downstream of the barrier coating application system for partially curing the applied barrier coating to enhance reception of CNT growth catalyst nanoparticles.

Abstract: A composition includes a carbon nanotube (CNT)-infused glass fiber material, which includes a glass fiber material of spoolable dimensions and carbon nanotubes (CNTs) bonded to it. The CNTs are uniform in length and distribution. A continuous CNT infusion process includes: (a) disposing a carbon-nanotube forming catalyst on a surface of a glass fiber material of spoolable dimensions; and (b) synthesizing carbon nanotubes on the glass fiber material, thereby forming a carbon nanotube-infused glass fiber material. The continuous CNT infusion process optionally includes extruding a glass fiber material from a glass melt or removing sizing material from a pre-fabricated glass fiber material.

Abstract: A composition includes a carbon nanotube (CNT)-infused carbon fiber material that includes a carbon fiber material of spoolable dimensions and carbon nanotubes (CNTs) infused to the carbon fiber material. The infused CNTs are uniform in length and uniform in distribution. The CNT infused carbon fiber material also includes a barrier coating conformally disposed about the carbon fiber material, while the CNTs are substantially free of the barrier coating. A continuous CNT infusion process includes: (a) functionalizing a carbon fiber material; (b) disposing a barrier coating on the functionalized carbon fiber material (c) disposing a carbon nanotube (CNT)-forming catalyst on the functionalized carbon fiber material; and (d) synthesizing carbon nanotubes, thereby forming a carbon nanotube-infused carbon fiber material.

Abstract: A composition includes a carbon nanotube (CNT)-infused metal fiber material which includes a metal fiber material of spoolable dimensions, a barrier coating conformally disposed about the metal fiber material, and carbon nanotubes (CNTs) infused to the metal fiber material. A continuous CNT infusion process includes: (a) disposing a barrier coating and a carbon nanotube (CNT)-forming catalyst on a surface of a metal fiber material of spoolable dimensions; and (b) synthesizing carbon nanotubes on the metal fiber material, thereby forming a carbon nanotube-infused metal fiber material.

Abstract: An electromagnetic missile launcher is disclosed that provides greater flexibility for use with a variety of missile types and also provides potentially higher performance and efficiency as compared to prior-art electromagnetic missile launchers.

Abstract: A mobile, telescoping radar array is disclosed. In some embodiments, the radar array has a plurality of support stages that fully nest when stowed and assume a telescoped form when deployed. A plurality of radiating elements depend from each stage. The support stages, as deployed, have a geometry that supports 360 degrees of radar coverage without rotating or otherwise repositioning the radar array.

Abstract: A “breathable” radome that has an air-permeable structure is disclosed. The air-permeable structure permits a relatively greater flow of cooling air to be drawn over the radiating elements of an air-cooling system that is used for the electronics that are being sheltered by the radome. The increase in cooling efficiency that results from the use of the breathable radome enables air-cooled systems to be used with relatively higher-powered electronics.

Abstract: A method is disclosed for forming a hollow tube, wherein the tube has a structural layer and a shield layer. The shield layer forms an inner surface of the tube. In some embodiments of the method, a coating, which forms the shield layer, is applied to a wash-out mandrel. The coating typically comprises a metal and/or a ceramic. A composite material, which in some embodiments is filamentous, is applied to (e.g., wound around, etc.) the coating to form the structural layer. In some embodiments, an optional transitional layer is applied to the coating before applying the composite material to enhance their compatibility. The various layers are cured, and then the mandrel is washed away to create the hollow or bore of the tube.

Abstract: Fiber tows are formed by situating carbon-nanotube-infused filaments in close proximity to one another, enabling the nanotubes on the filaments to interdigitate. In some embodiment, this enables the formation of fiber tows that do not require do not require resin impregnation.

Abstract: A continuous, plasma-based process for the production of carbon-nanotube-infused fibers is disclosed.

Abstract: A cold-gas munitions launch system is disclosed. In the illustrative embodiment, the system includes a munitions canister, a gas generator, and a sled. The sled supports a munition. The gas generator is located in the aft end of the munitions canister. When ignited, the gas generator produces gas, which drives the sled forward. As the sled reaches the end of the canister, the munition is launched by its own inertia, at a velocity that is within the range of about 3 to 9 g. After the munition clears the canister and travels at least about 150 feet from it, the munition's booster is ignited.
