Abstract: Articles coated with a water-resistant coating that absorbs water to provide the water-resistant effect, and desorbs water when the coating is dried, and a method of providing water resistance and corrosion resistance to articles prepared with such coatings. The coating is formed by applying a composition comprising an aqueous solution of a superabsorbent water-soluble polymer precursor, optionally a viscosity modifying agent, and optionally a lubricant onto the surfaces of the article, and curing to form a coating comprising the superabsorbent polymer.

Abstract: The fiber feed assembly includes one or more dampening bars arranged between a fiber source and an intake assembly that guides the fiber into an elongated feed tube through which the fiber is transferred for additional processing. The spacing and orientation of the dampening bar(s) relative to both the fiber source and the intake assembly may adjusted to control the fiber tension and remove fiber loops before the fiber enters the feed tube to reduce fiber breakage and machine downtime.

Abstract: The invention relates to an in-line process for producing high-temperature stable glass. A sizing composition is advantageously used to reduce plasticizing between the resinous matrix and the glass fibers. The in-line process uses a melter or furnace apparatus, including a top charging and melting section and an intermediate flow regulator section having a baffle system improving the heat pattern across the glass flow, and a bushing having a tip plate for receiving molten glass from a furnace. The bushing has an enlarged size that allows drawing of a significantly increased number of glass fibers at one time. The fibers have essentially no catenary and may be wound to create a tightly wrapped package of glass fibers of uniform exterior diameter throughout their width. High-strength, high-silica fiber made according to the invention may be advantageously used in filament-winding, pultrusion and weaving processes.

Abstract: A coating composition for forming a water-resistant coating on fiber-reinforced articles such as rods or cables. The composition comprises an aqueous solution of a superabsorbent water-soluble polymer, a viscosity modifying agent, and optionally a lubricant. The coating formed by applying the composition effectively prevents the treated surface from water-permeation damage by absorbing water that contacts the layer containing the superabsorbent component.

Abstract: An improved high-speed fiber assembly is provided comprising one or more dampening bars, an intake assembly, and feed tubes for transferring one or more fibers from an intermediate winding into one or more mechanisms for additional processing such as tensioning, prepregging, rewinding, weaving, or pultrusion.

Abstract: A process and apparatus are provided for positioning a plurality of reinforcement strands including a spliced reinforcement strand in a desired spatial relationship prior to a forming die. The process comprises the steps of: positioning a plurality of uninterrupted reinforcement strands moving toward a forming die so that the uninterrupted strands extend from a first location upstream of the forming die to the forming die in a space-apart converging configuration; and positioning at least one spliced reinforcement strand so that it extends generally centrally through the center of the converging configuration of the uninterrupted strands. The apparatus comprises first and second guide structures.

Abstract: Apparatus for producing continuous glass filaments is provided to facilitate the start-up or restart of a system wherein said filaments are attenuated by means of a rotatable member in contact with said filaments as a plurality of spaced apart bundles having a predetermined number of filaments in each bundle.

Abstract: Roving or beaming method and apparatus are provided in which a combined strand is produced from feeder packages. The passage of the strands from each feeder package is sensed, and the cessation of passage of strand from any one of the feeder packages results in the addition of a strand from an auxiliary package. Where strands are unwound from hollow feeder packages the auxiliary strand can be inserted into the interior of a feeder package for engagement with one of the feeder strands being unwound.
