The polymer matrix contains a thermoplastic polymer and the polymer matrix constitutes from about 30 wt. % to about 90 wt. % of the composition. The fibers have a nominal diameter of from about 20 micrometers to about 40 micrometers and constitute from about 10 wt. % to about 70 wt. % of the composition. Furthermore, the polymer composition defines a surface that exhibits a ΔE value of from about 0.6 to about 3 after being exposed to UV light at a total exposure level of 2,500 kJ/m2 according to SAE J2412_201508.

Abstract: A composite core for use in electrical cables, such as high voltage transmission cables is provided. The composite core contains at least one rod that includes a continuous fiber component surrounded by a capping layer. The continuous fiber component is 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 rovings 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 rovings 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. Notably, the desired strength properties may be achieved without the need for different fiber types in the rod.

The impregnation zone is configured to impregnate the plurality of rovings with the resin. The gate passage is in fluid communication with the impregnation zone for flowing the resin therethrough such that the resin impinges on a surface of each of the plurality of rovings facing the gate passage and substantially uniformly coats the plurality of rovings. The method includes impinging a polymer resin onto a surface of a plurality of fiber rovings, 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.

Abstract: A prepreg that contains a plurality of unidirectionally aligned continuous fibers embedded within a thermoplastic polymer matrix is provided. In addition to continuous fibers, the prepreg also contains a plurality of long fibers that are combined with the continuous fibers so that they are randomly distributed within the thermoplastic matrix. As a result, at least a portion of the long fibers become oriented at an angle (e.g., perpendicular) relative to the direction of the continuous fibers. Through such orientation, the long fibers can substantially increase the mechanical properties of the prepreg in the transverse direction (e.g., strength) and thus achieve a more isotropic material. Although unique isotropic prepregs are one aspect of the present invention, it should be understood that this is not a requirement. In fact, one notable feature of the present invention is the ability to tailor the mechanical properties of the prepreg for an intended application by selectively controlling certain process parameters, such as the type of long fibers employed, the type of continuous fibers employed, the concentration of the long fibers, the concentration of the continuous fibers, the thermoplastic resin(s) employed, etc.
