Fiber reinforced composite sheathing for storm protection

Abstract

A composite suitable as an integral portion of a building affording protection from wind blown debris such as from a tornado comprises a first layer of fabric of high strength fibers bonded with a resin and a second layer of a structural sheathing material such as plywood.

1 . A composite comprising: 
 (a) a first layer of a fabric containing high strength fibers bonded with a resin wherein the first layer will deflect in a range from 5.0 to 17.5 centimeters employing a 15 pound projectile at a speed of 161 kilometers (100 miles) per hour in accordance with ASTM test procedure E1886-97 mounted on one layer of ¾ inch plywood with #10d nails on a frame in accordance with FEMA Publication 320, Revision 1 specific to Drawings AG-5 and 14, and    (b) a second layer of structural sheathing.    
     
     
         2 . The composite of  claim 1  wherein the deflection is in a range from 8.0 to 16.0 centimeters.  
     
     
         3 . The composite of  claim 1  wherein the high strength fibers are selected from the group consisting of aramid fibers, glass fibers, polyethylene fibers, polyvinyl alcohol fibers, polyarylate fibers, polybenzazole fibers, or carbon fibers.  
     
     
         4 . The composite of  claim 1  wherein the high strength fibers comprise an aramid.  
     
     
         5 . The composite of  claim 1  wherein the high strength fibers are glass.  
     
     
         6 . The composite of  claim 1  wherein the second layer is at a thickness of at least 0.65 centimeters (one quarter inch).  
     
     
         7 . The composite of  claim 1  wherein the second layer comprises plywood.  
     
     
         8 . A building structure having an integral portion of the structure comprising a composite comprising: 
 (a) a first layer of a fabric containing high strength fibers bonded with a resin wherein the first layer will deflect in a range from 5.0 to 17.5 centimeters employing a 15 pound projectile at a speed of 100 kilometers (100 miles) per hour in accordance with test procedure E1886-97 mounted on one layer of ¾ inch plywood with #10d nails on a frame in accordance with FEMA Publication 320, Revision 1 specific to Drawings AG-5 and 14, and    (b) a second layer of a structural sheathing.    wherein the first layer faces an interior portion of the structure and the second layer faces or comprises an outer layer of the structure.    
     
     
         9 . The building structure of  claim 8  wherein the integral portion comprises a wall.  
     
     
         10 . The building structure of  claim 8  wherein the integral portion comprises a ceiling.  
     
     
         11 . The building structure of  claim 8  comprising the second layer of structural sheathing at a thickness of at least 0.65 centimeters (one quarter inch).  
     
     
         12 . The building structure of  claim 8  wherein the deflection is in a range from 8.0 to 16.0 centimeters.  
     
     
         13 . The building structure of  claim 8  wherein the high strength fibers are selected from the group consisting of aramid fibers, glass fibers, polyethylene fibers, polyvinyl alcohol fibers, polyarylate fibers, polybenzazole fibers, or carbon fibers.  
     
     
         14 . The building structure of  claim 8  wherein the high strength fibers comprise an aramid.  
     
     
         15 . The building structure of  claim 8  wherein the high strength fibers are glass.  
     
     
         16 . The building structure of  claim 8  wherein the second layer is at a thickness of at least 1.27 centimeters (one half inch).  
     
     
         17 . The building structure of  claim 8  wherein the second layer comprises plywood.  
     
     
         18 . A composite consisting essentially of: 
 (a) a first layer of a fabric containing high strength fibers bonded with a resin wherein the first layer will deflect in a range from 5.0 to 17.5 centimeters employing a 15 pound projectile at a speed of 161 kilometers (100 miles) per hour in accordance with ASTM test procedure E1886-97 mounted on one layer of ¾ inch plywood with #10d nails on a frame in accordance with FEMA Publication 320, Revision 1 specific to Drawings AG-5 and 14, and    (b) a second layer of structural sheathing.    
     
     
         19 . A building structure having an integral portion of the structure comprising a composite consisting essentially of: 
 (a) a first layer of a fabric containing high strength fibers bonded with a resin wherein the first layer will deflect in a range from 5.0 to 17.5 centimeters employing a 15 pound projectile at a speed of 100 kilometers (100 miles) per hour in accordance with test procedure E1886-97 mounted on one layer of ¾ inch plywood with #10d nails on a frame in accordance with FEMA Publication 320, Revision 1 specific to Drawings AG-5 and 14, and    (b) a second layer of structural sheathing.
