Abstract:
A rope structure adapted to engage an intermediate structure while loads are applied to ends of the rope structure comprises a primary strength component and a coating. The primary strength component comprises a plurality of fibers adapted to bear the loads applied to the ends of the rope structure. The coating comprises a mixture of a lubricant portion and a binder portion. The lubricant portion comprises particles having an average size of within approximately 0.01 microns to 2.00 microns. The binder portion is applied to the primary strength portion as a liquid and dries to support the lubricant portion relative to at least some of the fibers. The matrix supports the lubricant portion such that the lubricant portion reduces friction between at least some of the plurality of fibers and between at least some of the plurality of fibers and the intermediate structure.
Abstract:
There is provided a high-tensile synthetic fiber rope having a low percentage elongation, the rope dramatically improving the strength utilization rate of the tensile strength of the synthetic fibers, and ensuring the percentage elongation approximately the same as the percentage elongation of the synthetic fibers used in the rope. The synthetic fiber rope includes a plurality of strands twisted or braided together, each of the strands including: a tubular woven fabric woven with warp and weft yarns made of synthetic fibers; and a core material disposed in the tubular woven fabric, the core material being constituted by a plurality of parallel-bundled yarns made of the synthetic fibers in the tubular woven fabric.

Abstract:
A fire resistant rope and method of making the same. The fire resistant rope comprises a core, a jacket, and a fire retardant coating. The core comprises a plurality of strands. Each core strand comprises a plurality of core yarns, and each core yarn comprises a plurality of high tensile strength fibers. The jacket comprises a plurality of jacket strands. Each jacket strand comprises a plurality of jacket yarns and each jacket yarn comprises a plurality of high temperature resistant fibers. The fire retardant coating formed on at least one of the core and the jacket. The fire retardant coating expands when subjected to temperatures above a state-change level. At least a portion of the expanded coating inhibits transfer of heat to the core. The state-change level is below a failure temperature defined by the materials from which at least some of the fibers forming the core are formed.
