    摘要： An impregnation section (150) and a method for impregnating fiber rovings (142) with a polymer resin (214) are disclosed. The impregnation section (150) includes an impregnation zone (250) and a gate passage (270). The impregnation zone (250) is configured to impregnate the plurality of rovings (142) with the resin (214). The gate passage (270) is in fluid communication with the impregnation zone (250) for flowing the resin therethrough such that the resin impinges on a surface (216) of each of the plurality of rovings (142) facing the gate passage (270) and substantially uniformly coats the plurality of rovings. The method includes impinging a polymer resin (214) onto a surface of a plurality of fiber rovings (142), and substantially uniformly coating the plurality of rovings with the resin. The method further includes traversing the plurality of coated rovings through an impregnation zone (250). Each of the plurality of rovings (142) is under a tension of from about 5 Newtons to about 300 Newtons within the impregnation zone (250).

    摘要： An umbilical for the transfer of fluids and/or electric current/signals, particularly between the sea surface and equipment deployed on the sea bed (e.g., in deep waters), is provided. The umbilical contains a plurality of elongated umbilical elements (e.g., two or more), such as a channel element, fluid pipe, electric conductor/wire (e.g., optic fiber cable), armoring wire, etc., enclosed within an outer sheath (e.g., plastic sheath). The umbilical also contains at least one reinforcing rod formed from a plurality of unidirectionally aligned fiber rovings embedded within a thermoplastic polymer matrix. The present inventors have discovered that the degree to which the ravings are impregnated with the thermoplastic polymer matrix can be significantly improved through selective control over the impregnation process, and also through control over the degree of compression imparted to the ravings during formation and shaping of the rod, as well as the calibration of the final rod geometry. Such a well impregnated rod has a very small void fraction, which leads to excellent strength properties for reinforcing the umbilical elements.

    摘要： An asymmetric tape and a system and method for impregnating at least one fiber roving with a polymer resin to form an asymmetric tape are provided. The asymmetric tape includes a polymer resin, and a plurality of fibers embedded in the polymer resin to form a fiber reinforced polymer material. The fiber reinforced polymer material includes a first surface and an opposing second surface. The fibers are disposed in the fiber reinforced polymer material to form a resin rich portion and a fiber rich portion. The resin rich portion includes the first surface and the fiber rich portion includes the second surface.

    摘要： An impregnation plate and an impregnation section of a die for impregnating at least one fiber roving with a polymer resin are disclosed. The impregnation plate includes an impregnation zone configured to impregnate the roving with the resin. The impregnation zone includes an inner surface. The impregnation plate further includes a sidewall. The sidewall includes an inner surface. The inner surface of the sidewall includes a plurality of peaks and a plurality of valleys. At least one of the plurality of valleys defines a maximum height that is less than a height of the inner surface of the impregnation zone at a neighboring location along a run direction of the roving.
