Abstract:
A hybrid rope (40) or a hybrid strand (50) comprising a core element (42, 52), a first (44, 54) and a second (46, 56) metallic closed layer surrounding said core element (42, 52). The core element (42, 52) includes a bundle of synthetic yarns. The first metallic closed layer (44, 54) includes a plurality of first strands of wires helically twisted together with the core element (42, 52) in a first direction. The second metallic closed layer (46, 56) includes a plurality of second wires or strands helically twisted together with said core element (42, 52) and said first metallic closed layer (44, 54) in a second direction. The cross-sectional area of the core element (42, 52) is larger than the total cross-sectional area of the first (44, 54) and second (46, 56) metallic closed layers. A corresponding method of producing such a hybrid rope or hybrid strand is also disclosed.

Ein Aufzugseil (1) weist mehrere miteinander verseilte Stahldrahtlitzen (3) aus verseilten Stahldrähten (4) und eine von den Stahldrahtlitzen (3) umgebene Seileinlage (2) auf, wobei die Seileinlage aus einem Faserbündel hochfester Kunststofffasern besteht.
Abstract:
A method for forming a sling or a splice of an eye formed of coverbraided rope comprising the step of situating a void spacer adjacent to a portion of core rope. A method for producing a spliced sling of a coverbraided rope, the method comprising steps of : a) providing a void spacer; b) situating the void spacer alongside at least a portion of an intended splice braid zone of a strength member core; and c) covering at least portions of the void spacer with at least a portion of a braided sheath. A method for forming a high strength synthetic rope useful for towing warps, trawler warps, yachting ropes, mooring lines, anchoring lines, oil derrick anchoring lines, seismic lines, paravane lines, and any other uses for rope, cable or chain.
Abstract:
The cross-sectional area or diameter of an electric cable subjected to tensile stresses is minimized by means of a central, fibre-shaped element consisting of a bundle of carbon fibres (11). This embodiment can be achieved in a longitudinally watertight version and is suitable for trouble-free implementation, for example in cable looms.
Abstract:
L'invention concerne un câble de traction (1) comprenant une âme monobloc (2) comprenant un noyau central (4) muni sur sa périphérie d'une série d'ailettes (5) régulièrement espacées formant entre elles des gorges de réception (6) de section au moins partiellement circulaire et des torons (3) disposés autour de l'âme (2) par insertion dans chacune des gorges de réception (6), de telle sorte que l'association de l'âme et des torons (3) présente une enveloppe extérieure de forme sensiblement cylindrique, les torons (3) étant incrustés dans les gorges de réception (6), sans pour autant venir faire fluer les ailettes (5) qui les séparent. L'invention concerne également une âme monobloc (2, 7) pour câble de traction ainsi que l'utilisation de ce câble (1) en tant que câble de traction pure ou en tant que câble porteur-tracteur.
Abstract:
Hybrid rope (20) comprising a core element (22) containing high modulus fibers surrounded by at least one outer layer (24) containing wirelike metallic members (26). The core element (22) is coated (23) with a thermoplastic polyurethane or a copolyester elastomer, preferably the copolyester elastomer containing soft blocks in the range of 10 to 70 wt %. The coated material (23) on the inner core element (22) is inhibited to be pressed out in-between the wirelike members (26) of the hybrid rope (20) and the hybrid rope (20) has decreased elongation and diameter reduction after being in use.
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.
