Abstract

A composite bundle for repeated stress applications comprising at least one fiber of a high strength material, at least one fiber of fluoropolymer, wherein the fluoropolymer fiber is present in an amount of about 40% by weight or less.

Claims

exact text as granted — not AI-modified
1 . A composite bundle for repeated stress applications comprising: 
 (a) at least one high strength fiber having a tenacity of greater than 15 g/d; and    (b) at least fluoropolymer fiber comprising expanded polytetrafluoroethylene and selected from the group consisting of a monofilament or a multifilament;    wherein said fluoropolymer fiber is present in an amount of between about 1% and 40% by weight.    
   
   
       2 . The composite bundle of  claim 1  wherein said fluoropolymer fiber is present in an amount of between about 1% and 35% by weight.  
   
   
       3 . The composite bundle of  claim 1  wherein said fluoropolymer fiber is present in an amount of between about 1% and 30% by weight.  
   
   
       4 . The composite bundle of  claim 1  wherein said fluoropolymer fiber is present in an amount of between about 1% and 25% by weight.  
   
   
       5 . The composite bundle of  claim 1  wherein said fluoropolymer fiber is present in an amount of between about 1% and 20% by weight.  
   
   
       6 . The composite bundle of  claim 1  wherein said fluoropolymer fiber is present in an amount of between about 1% and 15% by weight.  
   
   
       7 . The composite bundle of  claim 1  wherein said fluoropolymer fiber is present in an amount of between about 1% and 10% by weight.  
   
   
       8 . The composite bundle of  claim 1  wherein said fluoropolymer fiber is present in an amount of about 1% by weight.  
   
   
       9 . The composite bundle of  claim 1  wherein said fluoropolymer fiber is a monofilament.  
   
   
       10 . The composite bundle of  claim 1  wherein said fluoropolymer fiber is low density of less than about 1 g/cc.  
   
   
       11 . The composite bundle of  claim 1  wherein said fluoropolymer fiber is a multifilament.  
   
   
       12 . The composite bundle of  claim 1  wherein said fluoropolymer fiber comprises a filler.  
   
   
       13 . The composite bundle of  claim 12  wherein said filler comprises carbon.  
   
   
       14 . The composite bundle of  claim 12  wherein said filler is selected from the group consisting of molybdenum disulfide, graphite, hydrocarbon, and silicone base fluid.  
   
   
       15 . The composite bundle of  claim 1  wherein the high strength fiber is para-aramid.  
   
   
       16 . The composite bundle of  claim 1  wherein the high strength fiber is polybenzoxazole (PBO).  
   
   
       17 . The composite bundle of  claim 1  wherein the high strength fiber is high tenacity metal.  
   
   
       18 . The composite bundle of  claim 1  wherein the high strength fiber is high tenacity mineral.
