Fluoropolymer fiber composite bundle
View Patent ↗A rope comprising a plurality of bundle groups, each of said bundle groups having a periphery and comprising a plurality of high strength fibers, at least one low coefficient of friction fiber disposed around at least a portion of the periphery of at least one of the bundle groups.
1. 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.
2. A rope as defined in claim 1 further comprising a plurality of said low coefficient of friction fibers, said low coefficient of friction fibers disposed around at least a portion of said periphery of a plurality of said bundle groups.
3. A rope as defined in claim 1 wherein said high strength fibers comprise ultra high molecular weight polyethylene.
4. A rope as defined in claim 1 wherein said high strength fibers comprise liquid crystal polymers.
5. A rope as defined in claim 1 wherein said high strength fibers comprise para-aramid.
6. A rope as defined in claim 1 further comprising an abrasion resistant coating.
7. A rope as defined in claim 1 used in a deep sea hardware delivery system.
8. 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.
9. 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.
10. 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.
