    摘要： A hollow lineal profile formed from a continuous fiber reinforced ribbon (“CFRT”) that contains a plurality of continuous fibers embedded within a first thermoplastic polymer matrix. To enhance the tensile strength of the profile, the continuous fibers are aligned within the ribbon in a substantially longitudinal direction (e.g., the direction of pultrusion). In addition to continuous fibers, the hollow profile of the present invention also contains a plurality of long fibers that may be optionally embedded within a second thermoplastic matrix to form a long fiber reinforced thermoplastic (“LFRT”). The long fibers may be incorporated into the continuous fiber ribbon or formed as a separate layer of the profile. Regardless, at least at a portion of the long fibers are oriented at an angle (e.g., 90°) to the longitudinal direction to provide increased transverse strength to the profile.

    摘要： 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.
