Synthetic Rope Development

This work addresses the US Navy's desire to develop a new generation of ropes for running rigging based on new advances in fibers, protective materials and manufacturing methods. Synthetic rope tensile strength and axial stiffness are similar to wire ropes, yet is much lighter, (20% compared to wire rope), and more flexible for easier rope handling. In addition, this technology provides excellent fatigue life; corrosion from salt-water environment; and excellent resistance to abrasion, wear, creep, and thermal degradation. This improved technology is available for underway replenishment (UNREP) applications, winches, elevators, towing (especially sensor arrays) and possibly in arrestor cables.
