    摘要: A process for manufacturing a continuous yarn, which entails the steps of: a) continously impregnating a mat of mechanically held-together fibers with a mixture of anhydrous size in a liquid state; b) continuosly taking up at least some of the mixture of the anhydrous size by a sizing roller in contact with the mat such that a liquid film having an almost constant thickness of less than 8 &mgr;m is formed thereon; and c) depositing the mixture of the anhydrous size, using the sizing roller, on a surface of at least some of a multiplicity of continuous filaments which are formed by mechanical drawing of at least a multiplicity of streams containing molten glass flowing out of orifices of at least one device.

    摘要: A method is disclosed for forming coated fibers suitable for making a composite article. A plurality of fibers are coated with an aqueous- or non-aqueous-based chemical treatment containing a curable resin such that the resin on the fibers is in a partially cured or uncured state. The coated fibers may then be formed into a composite article in a subsequent forming operation, for example, by filament winding, pultrusion, weaving, knitting, or extrusion coating. The strand of fibers may also be shaped into a preform which can be used in resin transfer molding (RTM) and injection molding processes.

    摘要: A method and apparatus are disclosed for the manufacture of an optical fiber preform having incorporated therein a comparatively high concentration of rare earth dopant material, and which thus can be drawn and processed into an optical fiber having low numerical aperture, low core attenuation, and high pumping power absorption. The high concentrations of rare earth dopant material are accomplished through either the “hybrid vapor processing” (HVP) method or a “hybrid liquid processing” (HLP) method, each capable of being practiced in combination or independently of one another. The HVP method involves the vaporization of a rare earth halogen by the exposure thereof to a sufficiently elevated temperature, independently, or contemporaneously with the transport of the resultant rare earth halogen laden vapor, into a glass forming oxidation reaction zone on a flowing stream of essentially an unreactive inert gas, such as helium. According to the HLP method, a first amount of rare earth dopant is provided according to the HVP method and/or other vapor source of rare earth dopant which is mixed with glass forming vapors to form a deposited soot layer on the internal surface of a glass tube. The soot-deposited tube is then impregnated with a dopant solution which may be formulated with a second amount of rare earth dopant. The tube is then thermally collapsed resulting in an optical preform with a an enhanced amount of incorporated first and second amounts of rare earth dopant.
