    摘要: An optical fiber ribbon comprises a plurality of optical fibers arranged in parallel and a connecting resin layer containing a ribbon resin for coating and connecting the plurality of optical fibers, wherein each of the plurality of optical fibers has an outer diameter of 220 µm or less; each of the plurality of optical fibers includes a glass fiber, a primary resin layer, and a colored secondary resin layer; the colored secondary resin layer contains a cured product of a resin composition containing 2,4,6-trimethylbenzoyldiphenylphosphine oxide; and a content of phosphorus in the colored secondary resin layer is 0.03 mass% or more and 0.30 mass% or less, and an amount of a phosphorus-tin complex at the surface of the colored secondary resin layer is 300 ppm or more and 7000 ppm or less.

    摘要: An elongate fiber artificial muscle includes or consists of an elongate carbon or glass fiber and at least a partial coating of a polymer, and preferably a full shell coating to form a core-shell arrangement, that is volumetrically responsive to thermal changes or to moisture changes. Additional elongate fiber artificial muscles of the invention include a plurality of elongate carbon or glass fibers that are infiltrated between the fibers with a polymer that is volumetrically responsive to thermal changes or to moisture changes. In a fabrication method, the rheology (flow characteristic) of a polymer precursor is adjusted with solvent so it is less viscous. A fiber or plurality of fibers (pre-twisted or untwisted), such as a tow is dipped in the polymer precursor. The fiber or fibers is then pulled out of the polymer precursor and hung to allow polymer to distribute and then cured and can be twisted to coil prior to curing. A model is provided to fabricate elongate fiber artificial muscle with specific characteristics based upon a thermal or moisture expansion coefficient of the polymer, its elongation capability percentage before flaking or breaking, and its elastic modulus.

    摘要: Fiber webs that may be coated and used in filter media are provided. In some embodiments, the fiber web is a non-woven web that is coated with a resin including at least two components (e.g., a first component and a second component) that may react with one another to form a copolymer. In some embodiments, the coated fiber web may be sufficiently self-supporting, durable, and strong, such that filter media and/or elements formed of the web do not require additional support structures (e.g., a scrim).
