Flexible puncture resistant sole

Abstract

A puncture or cut resistant protective sole for footwear made of woven fiber plies and flexible bonding agent disposed between adjacent woven fiber plies to define an alternating layered composite, wherein the flexible bonding agent penetrates into voids of each woven fiber ply and bonds fibers of each woven fiber ply to fibers within the same ply.

1 . A puncture or cut resistant protective sole for footwear comprising: 
 a plurality of woven fiber plies; and    a plurality plies of flexible bonding agent disposed between adjacent woven fiber plies to define an alternating layered composite, wherein the flexible bonding agent penetrates into voids of each woven fiber ply and bonds fibers of each woven fiber ply to fibers within the same ply.    
     
     
         2 . A sole according to  claim 1  wherein the bonding agent is selected from the group consisting of: rubber; plastic; and resin.  
     
     
         3 . A sole according to  claim 1  wherein the bonding agent is thermo-formable.  
     
     
         4 . A sole according to  claim 1  wherein the woven fiber plies comprise polyamide.  
     
     
         5 . A sole according to  claim 4  wherein the woven fiber plies comprise high-crystallized polymer fiber polyamide.  
     
     
         6 . A sole according to  claim 1  wherein the woven fiber plies have a common weave pattern.  
     
     
         7 . A sole according to  claim 1  wherein the thickness of the sole is in the range between 3 mm to 5 mm.
