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: Nuclear fuel structures and methods for fabricating are disclosed herein. The nuclear fuel structure includes a plurality of fibers arranged in the structure and a multilayer fuel region within at least one fiber of the plurality of fibers. The multilayer fuel region includes an inner layer region made of a nuclear fuel material, and an outer layer region encasing the nuclear fuel material. A plurality of discrete multilayer fuel regions may be formed over a core region along the at least one fiber, the plurality of discrete multilayer fuel regions having a respective inner layer region of nuclear fuel material and a respective outer layer region encasing the nuclear fuel material. The plurality of fibers may be wrapped around an inner rod or tube structure or inside an outer tube structure of the nuclear fuel structure, providing both structural support and the nuclear fuel material of the nuclear fuel structure.

摘要: Composite materials are provided which include a glass-ceramic matrix composition that is lightly crystallized, a fiber reinforcement within the glass-ceramic matrix composition which remains stable at temperatures greater than 1400° C., and an interphase coating formed on the fiber reinforcement. A method of making a composite material is also provided, which includes applying heat and pressure to a shape including fiber reinforcements and glass particles. The heat and pressure lightly crystallize a matrix material formed by the heat and pressure on the glass particles, forming a thermally stable composite material.
