Abstract:
To minimize the cross-sectional area or the diameter of an electric line that is under tensile stress, a central fibrous element of a carbon fiber bundle is disclosed. This can be designed so it is resistant to the longitudinal entry of water.
Abstract:
A wire rope for elevator systems used to hoist, compensate, and govern an elevator car. The wire rope may include six to ten outer steel strands surrounding a central braided polyester core. The wire rope may include six to ten outer steel strands and six to ten inner steel strands surrounding a central braided polyester core. The braided polyester core may include 8-24 single- or double-braided outer strands surrounding a polyester core center that may include parallel fibers, twisted fibers, twisted strands, single-braided strands, or double-braided strands.
Abstract:
Elevator coated ropes or belts are disclosed. The coated rope or belt may include at least one cord and a jacket retaining the at least one cord. The cord may include a plurality of filaments. The filaments are free of second-order helical structure. In a first embodiment, the filaments includes at least one inner filament and a plurality of outer filaments surrounding the at least one inner filament. The outer filaments are bunched together by forming a first-order helical structure through the length of the cord. In a second general embodiment, the filaments are free of both first- and second-order helical structures. The filaments are bunched together by a restraining loop or adhesive at one or more locations along the length of the cord. Methods of making the tension cord are also disclosed.
Abstract:
The invention relates to a hybrid rope having a core containing high modulus polyethylene (HMPE) yarns surrounded by an outer layer containing steel wire strands, wherein the core is coated with a plastomer, the plastomer being a semi-crystalline copolymer of ethylene or propylene and one or more C2 to C12 α-olefin co-monomers and the plastomer having a density as measured according to ISO1183 of between 870 and 930 kg/m3.

Abstract:
A reinforcing cord of the present invention is a reinforcing cord (10) for rubber reinforcement including a fiber core (11) and a plurality of strands (12) disposed around the fiber core (11). The fiber core (11) is formed of one or a plurality of highly elastic fibers having a tensile elastic modulus of at least 100 GPa. Each of the plurality of strands (12) is formed of a plurality of glass fibers that are primarily twisted, and the plurality of strands (12) are finally twisted to be disposed around the fiber core (11). The direction of the final twist of the plurality of strands is opposite to the direction of the primary twist in each of the plurality of strands (12). The number of final twists of the plurality of strands (12) is 1.0 to 3.0 times/25 mm, and a ratio of the number of primary twists in each of the plurality of strands (12) to the number of final twists of the plurality of strands (12) (the number of primary twists/the number of final twists) is in a range of 1.5 to 2.5.
Abstract:
A braided inner cable (10) for a mechanical control cable assembly (36) having a construction which provides for the use of fibers (14), (22) and (24) which are arranged in a three layer construction in which an inner longitudinal fiber core (12) is bound within a second braided fiber layer (16). A final pressure extruded outer jacket layer (30) surrounds the braided fiber layer (16), and permeates any spaces therebetween. The resulting inner control cable (10) is of a size and shape to fit standard commercially available outer cable housings (34). The inventive inner control cable (10) is intended to be used in applications such as for clutch cables on motorcycles and control cables on bicycles. Standard prior art ferrules (40), are installed on the inventive cable (10) by means of an epoxy adhesive (41).
Abstract:
A hybrid cable having a core and a wrap; the core made from a carbon fiber yarn or bundle of carbon fiber strands or yarns; and the wrap made of a plurality of metal wires helically wrapped around the core, the plurality of metal wires laid side by side without crossing each other. The fibers, yarns, or core may be treated with polymeric sizing, adhesive, or binder. The wire may be steel and may have a coating such as brass or zinc plating, or a polymeric coating or treatment. The hybrid cable is useful for reinforcing composite articles such as belts, track, or hose.
