Their missions often require that they cannot maintain cover providing individual protection. Body armor is commonly warn is such situations. Three levels of body armor are commonly known. Level I body armor is suitable to protect the wearer against low velocity pistol bullets, for example, 38 special at up to 850 Feet Per Second (FPS) and 22 at up to 1.050 FPS. Level II body armor is suitable to protect the wearer against 9 mm Full Metal Jacket (FMJ) at up to about 1.090 FPS and 357 Magnum Jacketed Soft Point (JSP) bullets at up to 1,250 FPS. Level III—A body armor is suitable to protect the wearer against 9 mm FMJ at up to 1,400 FPS (this may be from 9 mm sub machine gun or +P ammunition having much higher chamber pressure than common 9 mm ammunition) and 44 Magnum Semi Wadcutter (SWC) bullets at up to 1,400 FPS. Level III body armor is suitable to protect the wearer against standard military rifle ammunition such as the NATO 7.62 by 51 mm ammunition. While known body armor has been certified up to Level III, such body armor is expensive, heavy, and bulky. Therefore, a needs remains for better and less expensive body armor.

The ballistic vest 10 is designed to protect vital organs of a wearer without overly encumbering the wearer. The ballistic vest 10 includes shoulders 14 on each side of a neck opening 16, and arm cutouts 18. The ballistic vest 10 may be constructed using different embodiments of the ballistic material 12, as described below, to provide different levels of protection to the wearer. The ballistic material 12 may be worn exposed to view, or may be worn inside a garment concealed from view.
  • A front view of a single layer of mosaic pattern of panels 20 bonded to a mesh backing 24 for forming a protective layer 13 according to the present invention is shown in FIG. 2A, a side view of the protective layer 13 is shown in FIG. 2B, a front view of one of the panels 20 according to the present invention used for forming the protective layer 13 is shown in FIG. 3A, and a side view of one of the panels 20 is shown in FIG. 3B. The panels 20 are octagonal, but maybe other shapes, for example, hexagonal, square, triangular, and the like, and the protective layer 13 may be formed from panels having different shapes. In the case of octangular panels 20, small voids 22 result between the panels 20. The panels 20 are preferably arranged to limit vertical, horizontal, and/or diagonal gaps G between adjacent edges of the panels 20 to be less than 0.1 inches.
  • The panels 20 are formed from a core 28 of layers of woven inorganic material, set with epoxy resin, and sandwiched between plates made from. An example of a suitable material for the plates is aluminum or the like. The preferred woven inorganic material is sold by Barotex Technology Corporation under the trademark BAROTEX. For example, the core 28 may comprise layers of 6 ounce 3 by 1 twill unsized woven BAROTEX® material set with epoxy resin. BAROTEX® material is made from volcanic black rock and is described in U.S. Pat. No. 7,223,708 for “Inorganic Fabric” issued to the inventor of the present invention and incorporated herein in its entirety by reference. The core 28 preferably comprises between 30 and 40 layers of woven inorganic material, and more preferably between 35 and 40 layers of woven inorganic material, and the epoxy resin is preferably a high impact epoxy resin, for example, Parabond # 5130 or a similar resin made by Para-Chem Inc. in Simpsonville, S.C.
  • The core 28 is manufactured by pressing the layers of woven inorganic material together under between 300 and 400 Pound per Square Inch (PSI) and preferably under approximately 350 PSI and the core 28 is preferably between 3/16 and 5/16 inches thick and is more preferably approximately ¼ inches thick. The core 28 is preferable post cured for approximately two hours at approximately 475 degrees Fahrenheit to obtain full strength. Plates 26 a and 26 b are attached to opposite faces of the core 28 by fasteners (e.g., bolts), by setting in an autoclave, or by pressing and curing in a pressurized oven. The panels 28 may be manufactured as large plates and then after setting and/or curing, cut to a final size, for example, hexagonal in shape and approximately two inches across, although other shapes such as squares or triangles may also be utilized.
  • The panels 20 are bonded to a thin layer of mesh to allow the protective layer 13 to fit a wearer and to move with a wearer. The mesh 24 is preferably a mesh of inorganic material and more preferably a mesh of inorganic material made from volcanic black rock, and most preferably a mesh made from BAROTEX® material. The mesh 24 is preferably approximately 0.05 inches thick to separate consecutive layers of the plates 20 to allow the resulting ballistic material to flex.
  • A front view of overlapped protective layers 30 formed by overlapped protective layer 13 a and 13 b is shown in FIG. 4A and an edge view of the overlapped protective layers 30 is shown in FIG. 4B. The protective layers 13 a and 13 b are overlapped to leave no gap greater than the gaps G between adjacent edges of the panels 20 (see FIG. 2A).
  • A cross-sectional view of a level I ballistic material 36 according to the present invention is shown in FIG. 5 and a cross-sectional view of a level III ballistic material 38 according to the present invention is shown in FIG. 6. The level I ballistic material 36 is formed from two overlapping protective layer 13 a and 13 b, followed by a first layer of impact foam 32 a, for example, Advantic™ syntactic foam made by Cornerstone Research Group in Dayton, Ohio or a similar product, followed by a shock and deflection layer, for example, a layer of woven material 34, followed by a second layer of impact foam 32 b. The level III ballistic material 38 adds a third protective layer 13 c following the second layer of impact foam 32 b. Layers of impact foam 32 a and 32 b are preferably approximately ¼ inches thick. The layer of woven material 34 is preferably a shock resistant layer of multiple layers of woven inorganic fibers, and more preferably a layer of multiple layers of woven BAROTEX® material. The thickness of the layer of woven material 34 is dependent upon the level of protection required. For example, in the level I ballistic material 36, the layer of woven material 34 may comprise six or more layers of woven material 34, and in the level III ballistic material 38, the layer of woven material 34 is preferably a lay-up of six or more layers of six ounce woven inorganic fibers, and more preferably a lay-up of six or more layers of six ounce woven BAROTEX® material. The layers of impact foam 32 a and 32 b is preferably sown through to retain the layer of woven material 34 in position between the layers of impact foam 32 a and 32 b.
  • A layer of polymer is applied between each of the layers of the ballistic materials 36 and 38 to bond consecutive layers and to hold the fibers together while providing flexibility. The polymer layer is very flexible and thus allows the ballistic material to easily flex. An example of a suitable polymer is Tankskin® spray-on polymer made by Armor Systems International in Chatsworth, Calif.
  • While the invention herein disclosed has been described by means of specific embodiments and applications thereof, numerous modifications and variations could be made thereto by those skilled in the art without departing from the scope of the invention set forth in the claims.
