Claims10
A rope comprising
- a. a plurality of bundle groups, each of said bundle groups having a periphery and comprising a plurality of high strength fibers,
- b. at least one low coefficient of friction fiber disposed around at least a portion of said periphery of at least one of said bundle groups directly contacting a portion of said high strength fibers, wherein said low coefficient of friction fiber comprises expanded polytetrafluoroethylene,
- c. wherein said rope is a repeated stress application rope.
A bundle group for use in a rope for a repeated stress application comprising a periphery and comprising a plurality of high strength fibers and at least one low coefficient of friction fiber disposed around at least a portion of said periphery of said bundle group directly contacting at least one of said high strength fibers, wherein said low coefficient of friction fiber comprises expanded polytetrafluoroethylene.
A bundle for use in a rope for a repeated stress application comprising a periphery and comprising a plurality of high strength fibers and at least one low coefficient of friction fiber disposed around at least a portion of said periphery of said bundle, wherein said low coefficient of friction fiber comprises expanded polytetrafluoroethylene.
A method of making a rope having a plurality of bundle groups comprising the steps of 1) providing for each bundle group a plurality of high strength fibers, and 2) disposing around at least one of said bundle groups a low coefficient of friction fiber directly contacting at least one of said high strength fibers, wherein said low coefficient of friction fiber comprises expanded polytetrafluoroethylene.
