    摘要： The disclosed materials, methods, and apparatus, provide novel ultra-high temperature materials (UHTM) in fibrous forms/structures; such “fibrous materials” can take various forms, such as individual filaments, short-shaped fiber, tows, ropes, wools, textiles, lattices, nano/microstructures, mesostructured materials, and sponge-like materials. At least four important classes of UHTM materials are disclosed in this invention: (1) carbon, doped-carbon and carbon alloy materials, (2) materials within the boron-carbon-nitride-X system, (3) materials within the silicon-carbon-nitride-X system, and (4) highly-refractory materials within the tantalum-hafnium-carbon-nitride-X and tantalum-hafnium-carbon-boron-nitride-X system. All of these material classes offer compounds/mixtures that melt or sublime at temperatures above 1800° C.—and in some cases are among the highest melting point materials known (exceeding 3000° C.). In many embodiments, the synthesis/fabrication is from gaseous, solid, semi-solid, liquid, critical, and supercritical precursor mixtures using one or more low molar mass precursor(s), in combination with one or more high molar mass precursor(s). Methods for controlling the growth, composition, and structures of UHTM materials through control of the thermal diffusion region are disclosed.

    摘要： A process for producing-vapor grown carbon fiber (VGCF) reinforced continuous fiber performs for the manufacture of articles with useful mechanical, electrical, and thermal characteristics is disclosed. Continuous fiber preforms are treated with a catalyst or catalyst precursor and processed to yield VGCF produced in situ resulting in a highly entangled mass of VGCF infused with the continuous fiber preform. The resulting continuous fiber preforms are high in volume fraction of VGCF and exhibit high surface area useful for many applications. Furthermore, this invention provides for a continuous fiber preform infused with VGCF so that the carbon nanofibers are always contained within the fiber preform. This eliminates the processing steps for isolated carbon nanofibers reported in other carbon nanofiber composite approaches and therefore greatly reduces risk of environmental release and exposure to carbon nanofibers.

    摘要： Methods, processes, and apparatuses for the large scale synthesis of single-walled carbon nanotubes having small diameters are provided. Metal catalysts having small diameter and narrow distribution of particle sizes are prepared and continuously injected as aerosols into a reactor. The metal catalysts are supported on supports that are substantially free of carbon, and the reactor is configured to control the flow of the gases such that the reaction time and contact of the reactants with the reactor walls can be controlled. Single-walled carbon nanotubes can be continuously synthesized at a large scale and with high yields, and with small diameters and with narrow diameter ranges.
