摘要： A method for producing ceramic fibers of a composition in the SiC range, starts from a spinning material that contains a polysilane-polycarbosilane copolymer solution. The spinning material is extruded through spinnerets in a dry spinning method and spun through a spinning duct into green fibers, and the green fibers are subsequently pyrolyzed. Accordingly, the polysilane-polycarbosilane solution contains between 75 wt. % and 95 wt. %, in particular between 80 and 90 wt. %, of an indifferent solvent, and the spinnerets have a capillary diameter between 20 and 70 μm, in particular between 30 and 60 μm, in particular between 40 and 50 μm.

摘要： A composite protective yarn is incorporated into an article of apparel. The protective yarn has a core unit including a protective material selected from a group consisting of metallic filament, glass, and high tenacity fiber having a tensile strength of at least 7 grams per denier. A cover is applied to the core unit and is adapted for residing adjacent the skin. The cover includes an optically responsive material adapted for absorbing infrared radiation emitted from the human body at a first wavelength and returning the absorbed radiation to the body at a second longer wavelength. This relaxes capillaries and promotes increased blood flow to body parts covered by the article of apparel.

摘要： The method includes forming an inner monolithic layer from crystals of beta phase stoichiometric silicon carbide on a carbon substrate in the form of a rod by chemical methylsilane vapor deposition in a sealed tubular hot-wall CVD reactor. The method further includes forming a central composite layer over the inner monolithic layer by twisting continuous beta phase stoichiometric silicon carbide fibers into tows, transporting the tows to a braiding machine, and forming a reinforcing thread framework. A pyrocarbon interface coating is built up by chemical methane vapor deposition in a sealed tubular hot-wall CVD reactor. Then, a matrix is formed by chemical methylsilane vapor deposition in the reactor. A protective outer monolithic layer is formed from crystals of beta phase stoichiometric silicon carbide over the central composite layer by chemical methylsilane vapor deposition in a CVD reactor. And then the carbon substrate is removed from the fabricated semi-finished product.

摘要： A method and apparatus for forming a plurality of fibers from (e.g., CVD) precursors, including a reactor adapted to grow a plurality of individual fibers; and a plurality of independently controllable lasers, each laser of the plurality of lasers growing a respective fiber. A high performance fiber (HPF) structure, including a plurality of fibers arranged in the structure; a matrix disposed between the fibers; wherein a multilayer coating is provided along the surfaces of at least some of the fibers with an inner layer region having a sheet-like strength; and an outer layer region, having a particle-like strength, such that any cracks propagating toward the outer layer from the matrix propagate along the outer layer and back into the matrix, thereby preventing the cracks from approaching the fibers. A method of forming an interphase in a ceramic matrix composite material having a plurality of SiC fibers, which maximizes toughness by minimizing fiber to fiber bridging, including arranging a plurality of SiC fibers into a preform; selectively removing (e.g., etching) silicon out of the surface of the fibers resulting in a porous carbon layer on the fibers; and replacing the porous carbon layer with an interphase layer (e.g., Boron Nitride), which coats the fibers to thereby minimize fiber to fiber bridging in the preform.

摘要： A fireproof, translucent, flexible coated fabric composite material for use in fire curtains. The composite material meets or exceeds regulatory requirements in terms of fire endurance and allows transmissivity of necessary amounts of light. The process of the present disclosure combines a silica fabric with a special refractory index controlled resin. This unique combination of materials can transform an opaque high temperature fabric into a translucent, and even transparent, composite which as the ability to resist high temperature, flame and smoke penetration that fills a needed gap in technology between visibility and fire resistance in the field of fire and smoke curtains used in civil construction.

摘要： A fiber comprises a bulk material comprising one or more materials selected from the group consisting of carbon, silicon, boron, silicon carbide, and boron nitride; and a metal whose affinity for oxygen is greater than the affinity for oxygen of any of the one or more materials. The metal may be selected from the group consisting of beryllium, titanium, hafnium and zirconium. At least a first portion of the metal may be present in un-oxidized form at the entrance to and/or within grain boundaries within the fiber.A method of improving at least one of the strength, creep resistance, and toughness of a fiber comprises adding to a fiber, initially comprising a bulk material having a first affinity for oxygen, a metal that has a second affinity for oxygen higher than the first affinity. The metal may be selected from the group consisting of beryllium, titanium, hafnium and zirconium.
