摘要： A refractory oxide coated fiber is provided including a primary fiber material and a refractory oxide coating over the primary fiber material. Further, a method of making a refractory oxide coated fiber is provided, which includes: providing a first precursor-laden environment, the first precursor-laden environment including a primary precursor; promoting fiber growth within the first precursor-laden environment using laser heating; and providing a second precursor-laden environment to promote coating of the fiber, the second precursor-laden environment comprising a refractory oxide precursor, and the coating producing a refractory oxide coating over the fiber with a hexagonal microstructure.

摘要： A method of forming a high purity granular material, such as silicon carbide powder. Precursors are added to a reactor; at least part of a fiber is formed in the reactor from the precursors using chemical deposition interacting with said precursors; and the granular material is then formed from the fiber. In one aspect, the chemical deposition may include laser induced chemical vapor deposition. The granular material may be formed by grinding or milling the fiber into the granular material, e.g., ball milling the fiber. In one example, silicon carbide powder having greater than 90% beta crystalline phase purity and less than 0.25% oxygen contamination can be obtained.

摘要： A non-woven fabric is provided which includes a three-dimensional array of fibers. The three-dimensional array of fibers includes an array of standing fibers extending perpendicular to a plane of the non-woven fabric and attached to a base substrate, where the base substrate is one or more of an expendable film substrate, a metal base substrate, or a mandrel substrate. Further, the three-dimensional array of fibers includes multiple layers of non-woven parallel fibers running parallel to the plane of the non-woven fiber in between the array of standing fibers in a defined pattern of fiber layer orientations. In implementation, the array of standing fibers are grown to extend from the base substrate using laser-assisted chemical vapor deposition (LCVD).

摘要： A composite tape and method of fabrication are provided which includes multiple layers and a laser-driven chemical vapor deposition (LCVD)-formed additive material in at least one layer of the multiple layers to enhance one or more properties of the composite tape. The LCVD-formed additive material is a single crystalline material and can include LCVD-formed granular material and/or LCVD-formed fiber material in the same or different layers of the composite tape to enhance, for instance, fracture strength and/or wear resistance of the composite tape.
