It also concerns a glass fiber sized with the reaction product of said sizing composition, as well as a polymeric composite reinforced with such glass fibers.

An endless belt comprising a polyimide-based substrate layer. A plurality of boron nitride nanotubes are dispersed in the polyimide.

The present invention discloses an electrode material that eases electron injection and does not react with contact substances. The structure of the material includes a conductive substrate plane on the top of which an emissive material is coated. The emissive coating bonds strongly with the substrate plane. The emissive material is of low work function and high chemical stability.

The present invention relates to a surface modified overhead conductor with a coating that allows the conductor to operate at lower temperatures. The coating contains about 5% to about 30% of an inorganic adhesive, about 45% to about 92% of a filler, about 2% to about 20% of one or more emissivity agents, and about 1% to about 5% of a stabilizer.

There is provided a method of making a fiber having improved resistance to microfracture formation at a fiber-matrix interface. The method includes mixing a plurality of nanostructures and one or more first polymers in a first solvent to form an inner-volume portion mixture, mixing one or more second polymers in a second solvent to form an outer-volume portion mixture, spinning the inner-volume portion mixture and the outer-volume portion mixture to form a precursor fiber, heating the precursor fiber to oxidize the precursor fiber and to change a molecular-bond structure of the precursor fiber, and obtaining a fiber. The fiber has an inner-volume portion with a first outer diameter, the nanostructures, and with the one or more first polymers, and has an outer-volume portion with a second outer diameter and the one or more second polymers, the outer-volume portion being in contact with and completely encompassing the inner-volume portion.

Methods of producing continuous (or discontinuous) boron carbide fibers. The method comprises reacting a continuous or discontinuous carbon fiber material and a boron oxide gas within a temperature range of from approximately 1400 C. to approximately 2200 C. Articles including such partially or fully converted fibers may be provided, including such reinforcing fibers in a matrix of ceramic (a CMC), in metal (a MMC), or other matrix (e.g., polymer, etc.).
