Systems and methods are provided for braiding Metal Matrix Composite (MMC) tape. One method includes drawing multiple lanes of MMC tape, comprising a matrix of metal reinforced by fibers, from bobbins arranged around a mandrel. The method also includes braiding the multiple lanes to form a preform at the mandrel for an MMC part and consolidating the preform via application of heat and pressure.

MXene fibers and a preparation method thereof are provided. The method for preparation of a MXene fiber comprises preparing a dope solution in which MXene sheets are dispersed in a polar solvent, extruding the dope solution into a coagulating solution to coagulate the extruded dope solution to change into a MXene gel fiber, and drying the MXene gel fiber and converting it into the MXene fiber.

Provided are a high-entropy carbide ceramic, a rare earth-containing high-entropy carbide ceramic, fibers thereof, precursors thereof, and preparation methods thereof. The precursor includes at least four elements selected from Ti, Zr, Hf, V, Nb, Ta, Mo, and W, with each metal element accounting for 5-35% of the total molar quantity of metal elements in the precursor. The rare earth-containing high-entropy carbide ceramic precursor includes at least four transition metal elements and at least one rare-earth metal element. The high-entropy ceramic is a single-crystal-phase high-performance ceramic prepared from the precursor, with each element being homogenously distributed at molecular level. The method for preparing the high-entropy ceramic fiber includes uniformly mixing high-entropy carbide ceramic precursor containing target metal elements with spinning aid and solvent to prepare a spinnable precursor solution, followed by spinning, pyrolyzation, and high-temperature solid solution to prepare the high-entropy carbide ceramic fiber.

The present invention comprises the steps of contacting a boron nitride nanotube and a stabilizer in a solvent, and removing a portion of the solvent to obtain a liquid crystal composition including a liquid crystal in which at least a portion of the stabilizer is adsorbed on the surface of the boron nitride nanotube.

A hybrid woven textile for reinforcing a polymer matrix of a composite material that includes inorganic fibers selected from glass fibers, basalt fibers, carbon fibers, ceramic fibers, quartz fibers and silica fibers, and natural organic fibers, characterized in that the inorganic fibers and the natural organic fibers are co-woven, co-braided or co-knitted with one another.

Disclosed herein is a composite ply comprising fill and warp tows; or optional axial and bias tows; wherein one or more of the fill tows and/or the warp tows or wherein one or more of the optional axial and/or bias tows comprise a polymer yarn while the remaining portion of the fill tows and/or the warp tows or the remaining portion of the bias and/or optional axial tows comprise the polymer yarn; and wherein the polymer yarn is melted to bond to the fill or warp tows to prevent removal from the ply.

A method of producing, from a continuous or discontinuous (e.g., chopped) carbon fiber, partially to fully converted metal carbide fibers. The method comprises reacting a carbon fiber material with at least one of a metal or metal oxide source material at a temperature greater than a melting temperature of the metal or metal oxide source material (e.g., where practical, at a temperature greater than the vaporization temperature of the metal or metal oxide source material). Additional methods, various forms of carbon fiber, metal carbide fibers, and articles including the metal carbide fibers are also disclosed.

Systems and methods are provided for braiding Metal Matrix composite (MMC) tape. One method includes drawing multiple lanes of MMC tape, comprising a matrix of metal reinforced by fibers, from bobbins arranged around a mandrel. The method also includes braiding the multiple lanes to form a preform at the mandrel for an MMC part and consolidating the preform via application of heat and pressure.

Provided are a method of manufacturing MXene fibers and MXene fibers manufactured therefrom, wherein the method includes a) preparing a dispersion including MXenes; and b) spinning the dispersion in a coagulation solution to obtain MXene fibers.

The present invention relates to a textile cord comprising at least two yarns, each yarn comprising multiple filaments, wherein each filament comprises polyethylene furanoate reinforced by carbon nano material and/or boron nitride nano material. These textile cords are particularly useful as tire reinforcements. Moreover, the present invention is directed to a polymeric composition comprising (1) polyethylene-2,5-furan dicarboxylate and (2) a carbon nano material or a boron nitride nano material. This polymeric composition can optionally be further comprised of one or more additional polyesters, such as polyethylene terephthalate or polyethylene naphthalate. This invention is further directed to a rubber component comprising said cords coated with rubber and to tires and other rubber products comprising such cords.
