Abstract:
A two-component composite textile product constituted by a bundle that is mainly but not exclusively filament-like, with a diameter of even from approximately 2 mm to half a millimeter or less, whose strength, in conditions of inextensibility obtained by applying a traction load, can even reach and exceed 400 kg/mm 2 . Its cross-section is constituted by a core (A) of high-performance textile fiber (12) such as red "P.B.O.", in parallel rectilinear individual filaments which are mutually jointly connected by means of universal adhesive (3), stabilized so as to form a circular cross-section by helical winding with an individual stablizing filament (2) made of red "P.B.O." textile fiber; a sheath (4) made of white polyethylene fiber such as "HT" in chain-stitched fabric, or better in a knotless helix, constitutes a protective cladding.

Abstract:
Disclosed is a fiber reinforced plastic wire used as the overhead transmission cable. The fiber reinforced plastic wire for a strength member of an overhead transmission cable according to the present invention includes a wire having a predetermined diameter and composed of thermoset matrix resin; and a plurality of high strength fibers dispersed parallel to a longitudinal direction in an inside of the wire, the high strength fibers being surface-treated with a coupling agent to improve interfacial adhesion to the matrix resin. The fiber reinforced plastic wire of the present invention has the high tensile strength at the room temperature and the high temperature since its high strength fiber is surface-treated with a coupling agent. The fiber reinforced plastic wire can be also effectively used as the strength member in the overhead transmission cable since it has the excellent low coefficient of thermal expansion, etc. and is light-weight.

Abstract:
Provided is an elevator wire rope in which fiber cores having a high grease content are arranged in an empty space between center strands and inner-layer strands or an empty space between the center strands to improve flexibility while maintaining properties such as high elasticity and low elongation. The wire rope includes: a rope core including center strands and fiber cores, each of the center strands being formed by twisting wires; inner-layer strands each formed by twisting wires, the inner-layer strands being arranged around the rope core; and outer-layer strands each formed by twisting wires, the outer-layer strands being arranged around the inner-layer strands. The inner-layer strands are ten in number, and the outer-layer strands are ten in number. The fiber cores are arranged in at least one of an empty space between the center strands and the inner-layer strands and an empty space between the center strands.
Abstract:
Die Erfindung betrifft ein Verfahren zur Herstellung eines Seils (1), bei dem Faserbündel (2) zur Bildung von Faserlitzen (3) vor und/oder an einem Verseilpunkt mit einem verflüssigten Matrixmaterial (5) belegt und beim Verlitzen in das verflüssigte Matrixmaterial (5) eingebettet werden, mittels der Faserlitzen (3) ein Faserkern (6) des Seils (1) gebildet wird und um den Faserkern (6) Drähte oder Drahtlitzen (7) gewunden werden. Erfindungsgemäß wird das Matrixmaterial der Faserlitzen nach der Verlitzung verfestigt und die Faserlitzen (3) werden zur Bildung des Faserkerns (6) anschließend ohne weitere Belegung unmittelbar miteinander verseilt. Zweckmäßigerweise werden die Faserlitzen (3) bei oder nach ihrer Verseilung zu dem Faserkern (6) erwärmt derart, dass das Matrixmaterial (5) zumindest einzelner der Faserlitzen (3), vorzugsweise sämtliche der Faserlitzen (3), erweicht, sich mit dem Matrixmaterial (5) jeweils anderer der Faserlitzen (3) verbindet und anschließend unter Bildung eines Stoffschlusses untereinander verfestigt wird. Die Erfindung betrifft ferner ein mittels des Verfahrens herstellbares Seil.
