High temperature rigid repair wrap

Abstract

A high temperature repair wrap for repairing or strengthening an item. The high temperature repair wrap includes a fabric, where the fabric includes one or more fibers. The high temperature repair wrap further includes a hardening material disposed in the fabric. The high temperature repair wrap also includes a silicate disposed within the hardening material. The fabric is configured to be wrapped around a portion of an item. Curing the hardening material is configured to form a shell about the portion of the item.

         5 . The high temperature repair wrap of  claim 1 , wherein the hardening material includes:
 a water activated silastic resin.   
     
     
         6 . The high temperature repair wrap of  claim 5 , wherein the water activated silastic resin is between 25% and 30% of the repair wrap by weight. 
     
     
         7 . The high temperature repair wrap of  claim 1 , wherein the silicate includes:
 silicate includes fumed silica.   
     
     
         8 . The high temperature repair wrap of  claim 7 , wherein the fumed silica is between 5% and 10% of the repair wrap by weight. 
     
     
         9 . The high temperature repair wrap of  claim 1 , wherein the fabric is between 48% and 52% of the repair wrap by weight. 
     
     
         10 . The high temperature repair wrap of  claim 1 , wherein the one or more fibers are knit to form the fabric. 
     
     
         11 . A high temperature repair wrap for repairing or strengthening an item, the high temperature repair wrap comprising:
 a fabric, wherein the fabric includes:
 one or more fibers; and 
 the one or more fibers are knit to form the fabric; 
   a film disposed laterally within the fabric;   a resin disposed in the fabric, wherein the resin is:
 water activated; and 
 configured to cure in exposure to air; 
   a silicate disposed within the hardening material; and   wherein the fabric is configured to be wrapped around a portion of an item; and   wherein curing the hardening is configured to form a shell about the portion of the item.   
     
     
         12 . The high temperature repair wrap of  claim 11 , wherein the film includes a polyurethane film. 
     
     
         13 . The high temperature repair wrap of  claim 11 , wherein the resin includes an additive disposed in the resin. 
     
     
         14 . The high temperature repair wrap of  claim 13 , wherein the additive includes at least one of:
 plastic;   rubber;   sand;   wood particles;   sawdust;   fibrous material; or   polyester fibrous material.   
     
     
         15 . The high temperature repair wrap of  claim 11 , wherein the item comprises at least one of:
 wood;   metal;   glass;   plastic;   rubber;   composites;   fiberglass;   ceramic; or   concrete.   
     
     
         16 . A high temperature repair wrap for repairing or strengthening an item, the high temperature repair wrap comprising:
 a fabric, wherein the fabric includes:
 one or more fiberglass fibers; and 
 the one or more fibers are knit to form the fabric; 
   a polyurethane film disposed laterally within the fabric;   a resin disposed in the fabric, wherein the resin is:
 disposed on either side of the polyurethane film; 
 water activated; and 
 configured to cure in exposure to air; and 
   fumed silica disposed silicate within the hardening material;   wherein the fabric is configured to be wrapped around a portion of an item; and   wherein curing the hardening is configured to form a shell about the portion of the item.   
     
     
         17 . The high temperature repair wrap of  claim 16 , wherein the gauge of the knit fabric is between 11 stitches per inch and 17 stitches per inch. 
     
     
         18 . The high temperature repair wrap of  claim 17 , wherein the gauge of the knit fabric is approximately 14 stitches per inch. 
     
     
         19 . The high temperature repair wrap of  claim 16 , wherein the polyurethane film includes a dye, the dye configured to change the color of the polyurethane film.
