FIBER-REINFORCED COMPOSITE CABLE WITH TOW AND POWER TRANSMISSION LINE
Provided is a cable including a stranded member floating-preventing element that can be easily peeled off.
A power transmission line core includes one core member and six side members twisted around the core member, each member obtained by impregnating a fiber bundle including a plurality of carbon fibers that are continuous in the longitudinal direction and bundled into the fiber bundle with a resin and curing the resin. A tow including a plurality of tow fibers that are continuous in the longitudinal direction and arranged flatly and densely is spirally wound around the surface of the power transmission line core in the direction opposite to the twisting direction of the side members. The tow is detachably entangled in the unevenness on the surface of the power transmission line core.

Composite Control Cables and Stabilizing Tendons for Aircraft Applications and Method for Manufacture of Same
Control and stabilizing cables and tendons for high altitude aircraft and airships having lightweight, high strength and low CTE are disclosed, along with a method and machine for fabrication of same. The cable is comprised of a fiber prepreg tow encased in a polymer sleeve with one bobbin at each end to facilitate connections. Consolidating the fiber prepreg tow along the length of the cable using high temperature shrink tubing, such as polyvinylidene fluoride (PVDF), allows for eliminating the twisting of the fiber prepreg tow, thus reducing the number of wraps around the bobbins. Eliminating the twists in the fiber prepreg tow also reduces the length of fiber needed, and therefore the overall change in length of the control cable with temperature variations is reduced. Additional cable strength can be achieved by adding and holding significant tension on the fiber prepreg tow by applying weight during the curing process.
Compensating rope for an elevator
Elevator, which includes at least an elevator car and a device for moving the elevator car, preferably along guide rails, and a counterweight, and one or more ropes, which rope connects the elevator car and the counterweight and is separate from the supporting function and passes around a diverting pulley mounted on the bottom end of the elevator hoistway. The rope comprises a power transmission part or a plurality of power transmission parts, for transmitting power in the longitudinal direction of the rope, which power transmission part is essentially fully of non-metallic material.
