Abstract:
A rope having an outer jacket made of braided fibers surrounding a PTFE core and a method for making the rope. The rope is useful in high-tension, high-friction applications, such as serving as a stress member in an isolation section of an instrumented ocean-bottom cable. The PTFE core, which may consist of one or more strings of PTFE valve packing material, squeezes through the braided jacket as the rope is deformed in high-stress regions such as around a bollard. The PTFE material squeezed through the outer jacket lubricates the outside of the rope in the high-stress region to lower the friction.
