摘要： A composite with a thermoplastic matrix and fiber reinforcement is made by rotation of an exit die about a roving of continuous fiber in the presence of a thermoplastic melt. The rotation causes opposing inner and outer helical flow conditions which reduce the melt viscosity of the polymer by shear thinning while dragging and directing the polymer into the fiber roving thereby wetting and dispersing the fiber. A composite structure is formed with a polymer rich skin and a core region of unidirectionally aligned polymer and fiber. The polymeric skin is composed of helically aligned polymer chains which are coiled by the rotation around the core to compress the core region and enhance fiber wet out.

摘要： Disclosed is a process for manufacturing a conductive fiber-PVC composite which exhibits less than 10.sup.12 hms/sq. resistivity. The process entails incorporating into rigid PVC under heat and shear, a composite of parallel, conductive long fibers embedded in a PVC-dispersible matrix. The process is conducted under the same melt process conditions encountered in the compound processing of rigid PVC, and the long conductive fibers are incorporated a long fiber composite of substantially parallel fibers embedded in a PVC dispersible matrix. The pellets comprise from about 20% to 80% by weight of conductive fiber and 80% to 20% PVC-dispersible thermoplastic.

摘要： There is provided an elongate fiber reinforced thermoplastic composite which comprises a multiplicity of filamentary fibers, each extending longitudinally of the composite and a thermoplastic resin matrix impregnating and surrounding the filamentary fibers. The composite has alternating lobes and valleys on its surface defining a fluted cross section. The lobes and valleys extend helically along the longitudinal axis of the composite. In a preferred form of the invention, the filamentary fibers also extend helically along the longitudinal axis of the composite, and desirably, the helical pitch of the filamentary fibers is substantially the same as that of the lobes and valleys. The helical pitch may suitably range from about 1.5 to about 8 inches and the elongate composite may have a diameter of from 0.125 to 8 inches. The fibers may comprise from about 20 to about 80 percent by weight of the composite. The number of fibers in the elongate composite may be within the range of 2,000 to 70,000,000 filaments.

摘要： This invention relates to fiber reinforced composite materials, and to methods and apparatus for forming such materials. The apparatus includes an impregnation chamber having an elongate impregnation passageway with an entrance end and an exit end, means for supplying a polymer material to said impregnation chamber, and means for advancing continuous filament fibers into and through said impregnation chamber, entering through said entrance end and exiting through said exit end, so that the polymer material is immersed in said polymer material. Shear inducing means is mounted in said impregnation chamber and cooperates with said fibers for imparting shear to the polymer material as it contacts the advancing fibers to enhance the wetting and impregnation of the fibers by the polymer material.

摘要： This invention relates to composite materials formed by thermoplastic materials reinforced by fibers, and to methods and apparatus for forming such materials, where the thermoplastic and fiber components are such as to impart to the composite materials enhanced strength as compared with materials made previously to this invention. An important distinguishing characteristic of the disclosure is that advancing heated fiber is directed to move in one direction and while a flow of heated thermoplastic material is directed to move in a direction opposite to and in intimate impregnating enclosure of the advancing heated fiber, so that shear forces arising between the advancing heated fiber and the directed flow of thermoplastic material promote wetting and impregnation of the fiber by the thermoplastic material.
