    Abstract: A hybrid rope constructed of a plurality of strands, wherein each strand is constructed of a fiber center, a jacket surrounding the fiber center, and a plurality of wires surrounding the jacket. The fiber center can be constructed of one or more high-strength synthetic fibers or yarns. The jacket can be constructed of polypropylene, thermoplastic polyurethane, high-density polyethylene, linear low-density polyethylene, nylon or other similar materials. The jacket can have a braided or woven design and adds a protective layer between the fiber center and the wires. The wires can be constructed of high-strength steel wires, galvanized steel or stainless steel. The fibers or yarns that make of the fiber center are twisted to lay right and then covered with the jacket. The wires then surround the jacket and are twisted to lay to the left. This creates a torque-balanced condition of the hybrid rope.

    Abstract: The present invention pertains to a UHMWPE film having a tensile strength of at least 2.0 GPa, a tensile energy to break of at least 30 J/g, an Mw of at least 500 000 gram/mole, and a Mw/Mn ratio of at most 6. The film may be manufactured via a process which comprises subjecting a starting UHMWPE with a weight average molecular weight of at least 500 000 gram/mole, an elastic shear modulus determined directly after melting at 160° C. of at most 0.9 MPa, and a Mw/Mn ratio of at most 6 to a compacting step and a stretching step under such conditions that at no point during the processing of the polymer its temperature is raised to a value above its melting point. The film may be used as starting material in any applications where high tensile strength and high energy to break are important. Suitable applications include ballistic applications, ropes, cables, nets, fabrics, and protective applications.

    Abstract: A reinforcing steel cord for rubber products, such as steel belted radial tires or conveyor belts, is disclosed. This steel cord is improved in rubber penetration and ageing adhesive force relative to the rubber material. The steel cord is formed by twisting a plurality of brass coated external element wires around a flat and spirally twisted core, with the twisted direction of the core being the same as or opposite to that of the resulting steel cord. In the steel cord, the pitch of the twisted core is set to allow the core to be twisted 0.2 to 2 times within the pitch of the cord, thus preferably forming sufficient interspaces between the core and the external wires in addition to the interspaces between the external wires. Since the rubber material is completely filled in the steel cord due to such interspaces, the steel cord is remarkably improved in buckling fatigue resistance, rubber penetration, air permeability, rubber adhesive force, ageing adhesive force relative to rubber, protection of brass coated surfaces of wires, and workability during a process of producing rubber products. The steel cords of this invention are most preferably used as a reinforcing material for steel belted radial tires.
