Ballistic structural insulated panel

Abstract

One or more embodiments contained herein disclose a structural insulated panel having improved ballistics properties and methods for using the same.

1 . A ballistic panel comprising:
 a strike face;   a first spall section;   a structural insulated panel;   a second spall section; and   at least one decorative skin disposed on the strike face or the second spall section;   wherein the first spall section is disposed on a first side of the structural insulated panel and the second spall section is disposed on a second side of the structural insulated panel.   
     
     
         2 . The ballistic panel of  claim 1 , wherein the strike face comprises a metal or a ceramic. 
     
     
         3 . The ballistic panel of  claim 2 , wherein the strike face comprises one of aluminum or steel. 
     
     
         4 . The ballistic panel of  claim 2 , wherein the strike face comprises one of alumina, silicon carbide, or boron carbide. 
     
     
         5 . The ballistic panel of  claim 1 , wherein the first spall section comprises at least
 one of: E-glass, R-glass, S-glass, Aramid, UHMWPE, or polypropylene fiber and a polymer resin.   
     
     
         6 . The ballistic panel of  claim 1 , wherein the second spall section comprises at least one of: E-glass, R-glass, S-glass, Aramid, UHMWPE, or polypropylene fiber and a polymer resin. 
     
     
         7 . The ballistic panel of  claim 1 , wherein the structural insulated panel comprises a first skin, a core, and a second skin. 
     
     
         8 . The ballistic panel of  claim 7 , wherein the core comprises a rigid polymer. 
     
     
         9 . The ballistic panel of  claim 8 , wherein the rigid polymer comprises polystyrene or polyurethane. 
     
     
         10 . The ballistic panel of  claim 7 , wherein the first skin comprises one or more of steel, aluminum, cement, plastic, or fiber reinforced plastic. 
     
     
         11 . The ballistic panel of  claim 7 , wherein the second skin comprises one or more of steel, aluminum, cement, plastic, or fiber reinforced plastic. 
     
     
         12 . The ballistic panel of  claim 7 , wherein the core is disposed between the first skin and the second skin. 
     
     
         13 . The ballistic panel of  claim 1 , wherein the ballistic panel comprises a V 50  of at least 3300 fps. 
     
     
         14 . A method of slowing a projectile comprising:
 providing a ballistic panel comprising a strike face configured to engage a spall section, a first spall section configured to engage a structural insulated panel, a structural insulated panel, a second spall section, and at least one decorative skin disposed on the strike face and or the second spall section;   absorbing an initial impact of the projectile;   tumbling the projectile in the structural insulated panel; and   slowing the projectile in the second spall section.   
     
     
         15 . The method of  claim 14 , further comprising ceasing motion of the projectile in the second spall section. 
     
     
         16 . A ballistic panel comprising:
 a strike face;   a first spall section;   a structural insulated panel;   a second spall section; and   wherein the first spall section is disposed on a first side of the structural insulated panel and the second spall section is disposed on a second side of the structural insulated panel.
