Rope structure with improved bending fatigue and abrasion resistance characteristics

A method of forming a rope structure adapted to engage an intermediate structure while loads are applied to ends of the rope structure, comprising the steps of:

• providing a plurality of fibers;
• combining the plurality of fibers to form a primary strength component adapted to bear the loads applied to the ends of the rope structure;
• providing a coating material in liquid form comprising a lubricant portion and a binder portion, where the lubricant portion is formed by at least one of particles, where an average particle size of the particles is within approximately 0.01 microns to 2.00 microns;
• applying the coating material in liquid form to the primary strength component;
• allowing the coating material in liquid form to dry on the primary strength member such that the binder portion forms a matrix that at least partly surrounds at least some of the fibers to support the lubricant portion relative to at least some of the fibers 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.

A rope structure adapted to engage an intermediate structure while loads are applied to ends of the rope structure, comprising:

• a primary strength component comprising a plurality of fibers adapted to bear the loads applied to the ends of the rope structure, where the plurality of fibers are combined to form plurality of yarns, the plurality of yarns are combined to form a plurality of strands, and the plurality of strands are combined to form the primary strength component;
• a coating comprising particles suspended within a matrix formed of binder material such that the binder fixes the particles relative to at least some of the fibers such that the particles reduce friction between at least some of the plurality of fibers and between at least some of the plurality of fibers and the intermediate structure;
• wherein
• the coating is formed by applying coating material in a liquid form to the primary strength component;
• the liquid form of the coating material comprises substantially between 5% and 40% by weight of the lubricant portion;
• and
• an average size of the particles is within approximately 0.01 microns to 2.00 microns.

• a binder portion, where the binder portion is applied to the primary strength portion to form a matrix that at least partly surrounds at least some of the fibers to support the lubricant portion relative to at least some of the fibers;
• whereby
• the matrix supports the lubricant portion such that the lubricant portion
• reduces friction between at least some of the plurality of fibers, and
• reduces friction between at least some of the plurality of fibers and the intermediate structure;
• and
• the lubricant portion is formed by particles having an average size of within approximately 0.01 microns to 2.00 microns.
