Plastic encased multi-threat anti-ballistic material

Abstract

A new plastic encased anti-ballistic material, one which may be tailored for multi-threat protection. Also disclosed is a method for forming such a new anti-ballistic material or article by describing a method of forming plastic particulates into a multiple skin configuration, usually two skins, which may also have contained therebetween either an expandable plastic material, along with the anti-ballistic material reinforcement for strengthening the plastic article, other filler materials, or combinations thereof. In addition to the materials which can be incorporated into the middle layer between two skins, the present invention also discloses the use of multiple layers of various types of anti-ballistic materials to combat any type of ballistic threat which may happen.

1 . An anti-ballistic article, comprising:
 a first outer structural skin of polyolefinic material;   a second outer structural skin of polyolefinic material opposite said first outer skin;   an expandable material between the first and second skins;   at least one layer of anti-ballistic material embedded in the expandable material and being encased between the first and second skins,   whereby an anti-ballistic article is formed having superior anti-ballistic retention properties.   
     
     
         2 . The article of  claim 1 , wherein the first and second structural skins are rigid polyolefinic material skins from about 1 mm to about 10 mm in thickness made from a material selected from the group consisting of polypropylene, polyurethane, thermoplastics, thermoset resins, and any combination thereof. 
     
     
         3 . The article of  claim 1 , wherein the expandable material between the skins is made of a foamable polyolefinic material, to encase the anti-ballistic material between the two outer skins, as well as holding the anti-ballistic material securely in place within the foamed up expandable material. 
     
     
         4 . The article of  claim 1 , wherein the at least one layer of anti-ballistic material embedded in the expandable material and being encased between the first and second skins is selected from the group consisting of may be selected from the group consisting of aramid fibers, Kevlar, Dyneema, para aramids such as PBO, Zylon™, various denier Kevlar™ KM2 materials such as 500 or 400 denier material, Kevlar™ 129 500 or KMz 600, and 400 denier material, Spectra™ polyethylene fabrics, and Dyneema™ polyethylene fabrics such as their SB31, bullet-proof steel, bainite steel, boron carbide, silicon carbide, silicon nitride, alumina, or any other carbide, nitride, oxide or any other suitable ceramic material, or any version of any of these ceramics or metals, and combinations thereof, whether singly or multiple layers. 
     
     
         5 . The article of  claim 1 , wherein the anti-ballistic article is an integral composite article that will not delaminate. 
     
     
         6 . The article of  claim 1 , wherein the anti-ballistic article is a formed unitary piece with structural integrity for purposes of mufti-threat ballistic qualities. 
     
     
         7 . A multi-threat integral anti-ballistic article, comprising:
 a first outer structural skin of polyolefinic material;   a second outer structural skin of polyolefinic material opposite said first outer skin;   a filler material between the first and second skins;   at least one layer of sheeted aramid fiber anti-ballistic material and a layer of plate steel embedded in the filler material and being encased between the first and second skins and held in place within the structural skins,   whereby an anti-ballistic article is formed having superior anti-ballistic retention properties.   
     
     
         8 . The article of  claim 7 , wherein the first and second structural skins are rigid polyolefinic material skins from about 1 mm to about 10 mm in thickness made from a material selected from the group consisting of polypropylene, polyurethane, thermoplastics, thermoset resins, and any combination thereof. 
     
     
         9 . The article of  claim 7 , wherein the expandable material between the skins is made of a foamable polyolefinic material, to encase the anti-ballistic material between the two outer skins, as well as holding the anti-ballistic material securely in place within the foamed up expandable material. 
     
     
         10 . The article of  claim 7 , wherein the at least one layer of anti-ballistic material embedded in the expandable material and being encased between the first and second skins is selected from the group consisting of may be selected from the group consisting of aramid fibers, Kevlar, Dyneema, para aramids such as PBO, Zylon™, various denier Kevlar™ KM2 materials such as 500 or 400 denier material, Kevlar™ 129 500 or KMz 600, and 400 denier material, Spectra™ polyethylene fabrics, and Dyneema™ polyethylene fabrics such as their SB31, bullet-proof steel, bainite steel, boron carbide, silicon carbide, silicon nitride, alumina, or any other carbide, nitride, oxide or any other suitable ceramic material, or any version of any of these ceramics or metals, and combinations thereof, whether singly or multiple layers. 
     
     
         11 . The article of  claim 7 , wherein the anti-ballistic article is an integral composite article that will not delaminate.
