DESCRIPTION
[0018] As mentioned earlier, ballistic resistant body armor plates are typically used in conjunction with a ballistic resistant vest and provide additional ballistic resistant protection. However, in some instances where additional weight is a concern to the wearer ballistic armor plates are used in association with a carrier and without the use of a ballistic resistant vest. The wearer of the ballistic resistant vest will insert the ballistic resistant body armor plates into or otherwise secure the plates to the ballistic resistant vest. The plates will be strategically positioned at locations so as to provide enhanced protection of vital organ(s) of the wearer at those locations. As discussed earlier, the ballistic resistant body armor plate(s) will typically be fabricated to provide the location(s) with protection from a higher caliber weapon or rifle which may be above the design of the ballistic vest. In some applications armor plates may be used in conjunction with a ballistic resistant vest to thwart other threats than ballistic. Ballistic resistant body armor plates are constructed from one or more ballistic resistant materials. There are a wide variety of constructions and compositions of ballistic resistant body armor plates which the fabricator can select from to address ballistic resistant needs for the wearer.
[0019] As discussed earlier, ballistic impact onto a ballistic resistant body armor plate can result in some unwanted events or occurrences, as discussed earlier. The unwanted events may occur based on a number of different factors. Some of these factors can include the particular construction of the ballistic resistant body armor plate, the hardness of the strike surface of the plate, the velocity, size and makeup of the projectile and the angle of impact of the projectile. Any one of or a combination of these factors may contribute to an unwanted event as a result of a ballistic impact to the armor plate.
[0020] In an example of a ballistic impact where the construction of the ballistic resistant body armor plate is a laminate structure, a ballistic impact on the strike face can impart an undesired shear force onto the laminate. A sufficient shear force can promote an unwanted delamination of the ballistic resistant body armor plate rendering the body armor plate subsequently less or none effective. Providing secure confinement of a laminated armor plate provides alignment support to the laminated structure so as to reduce the occurrence of and/or the effect of a delamination event.
[0021] In an example of a ballistic impact where the ballistic resistant body armor plate is constructed of a particularly hard surface, such as that of ceramic or metal material, a ballistic impact on the strike face of the ballistic resistant armor plate can contribute to an undesired spalling event occurring at the strike face. Spalling results in unwanted fragment projectile(s) originating from the breaking up of the original impacting projectile, from breaking up of a portion of the body armor plate at the point of impact or from both. Similarly, in the instance where certain hard surface of the ballistic resistant plate is impacted by a ballistic round with an angular impact, an unwanted ricochet can occur. Providing resilient confinement of the armor plate will assist in mitigating unwanted fragment projectiles.
[0022] In another example of an unwanted event occurring at the time of a ballistic impact on a strike face of a ballistic resistant body armor plate, the impact can result in an unwanted back face deformation of the body armor plate causing injury to the wearer. A cushioned resilient confinement of the ballistic armor plate can provide mitigation of injury to the wearer with a cushioned distribution of force to the wearer from the deformation.
[0023] Mitigation of unwanted occurrences or events such as delamination, spalling and/or back face deformation from a ballistic impact onto the ballistic resistant body armor plate would be beneficial to the wearer. The ballistic resistant body armor plate assembly to be described herein will provide mitigation with respect to these unwanted occurrences or events from a ballistic impact onto a ballistic resistant body armor plate with providing a secure encapsulation of a solid foam material about a ballistic resistant body armor plate.
[0024] In addition, it would be beneficial to minimize the weight associated with a body armor plate assembly having an enclosing feature so as to minimize fatigue to the wearer. It would also be beneficial to provide buoyancy to a ballistic resistant body armor plate so as to provide the wearer additional safety should the wearer be subjected to a water environment while wearing a ballistic resistant vest which carries ballistic resistant body armor plates or with, as mentioned earlier, wearing a carrier carrying ballistic resistant body armor plates. The ballistic resistant body armor plate assembly to be described herein will provide minimizing of the weight related to a body armor plate assembly and maximizing the buoyancy of the body armor plate assembly with providing an encapsulation of a solid foam material about the ballistic resistant body plate, as will be described herein.
[0025] Additionally, it would beneficial to provide protection to ballistic resistant body armor plates constructed of a hard material such as ceramic so as to reduce the occurrence of chipping and/or cracking of the ceramic material should the armor plate be dropped or otherwise experience impact with a hard surface. The ballistic resistant body armor plate assembly to be described herein will provide this benefit with encapsulating the ceramic armor plate with a solid foam providing a resilient protective covering to the ceramic armor plate.
[0026] In referring to
[0027] Armor plate assembly 10 can be inserted within or otherwise secured to a ballistic resistant vest providing needed strategic additional ballistic protection for the wearer, as is the case for all examples of armor plate assemblies discussed herein. Armor plate assembly 10 and the other examples described herein can also be used in association with a carrier and employed in the construction of a ballistic shield and in the construction of a ballistic barrier. As mentioned above, the armor plate assemblies can be also carried within a carrier without the employment of a ballistic resistant vest. Additionally, the armor plate assembly technology described herein can also be applied to the construction of ballistic shields and/or ballistic barriers, as mentioned earlier. As shown in
[0028] Strike face S and back face B of first example of ballistic resistant body armor plate assembly 10 demonstrates the orientation of body armor plate assembly 10 as worn by the wearer. This orientation is also provided for second example of body armor plate assembly 10, as shown in
[0029] The dimensions of coverage provided to the wearer of the armor plate assembly for each of the first, second and third examples 10, 10and 10 respectively can vary as can the thickness for the armor plate assemblies. Ballistic resistant body armor plates are made in numerous coverage dimensions for the wearer, configurations and thicknesses. In first example 10 shown in
[0030] With respect to armor plates used with concealed ballistic resistant vests are generally constructed with smaller dimensions of coverage and smaller thicknesses than ballistic resistant body armor plates used with strategic ballistic resistant vests. Dimensions of coverage and thicknesses of the body armor plates will be determined and provided as needed for the particular protection required.
[0031] An outer portion of the first example of body armor plate assembly 10 includes a solid foam material which will be discussed in more detail herein. Solid foam material 14 overlies opposing sides of armor plate 16 as shown for example in
[0032] Armor plate 16 for all of first, second and third examples 10, 10 and 10 can be constructed from one of many different constructions and be composed of one of or a combination of compositions used for making armor plate 16. Materials or compositions that are considered in the construction of armor plate 16 include materials, as mentioned earlier, such as: metal, ceramic, fabric, plastic, woven fabrics, composites, carbon nanotube, nano-composite materials as well as graphenes and others. These materials can be used alone or in select combination with each other and/or with other materials used in the construction of armor plates. It is often the case, with fabricating plates for higher ballistic ratings under NIJ standards, to use more than one of these materials. The fabricator can choose one or more materials as needed to provide the protection to the wearer that is needed. For construction of armor plate 16 for any of the examples of ballistic resistant body armor plate assemblies 10, 10 and 10, the ballistic stopping capability of armor plate 16 will be greater than the other component(s) used in the construction of these assemblies 10, 10 and 10.
[0033] These different constructions and compositions for armor plates 16 are known in the industry. One material for example includes the use of metals such as for example steel, titanium, aluminum and various alloys. Metal materials are known to be well suited for reducing blunt trauma and for breaking up of an impacting ballistic projectile.
[0034] Other materials used in the fabrication of armor plate 16 include ceramics such as those which include boron carbide and silicon carbide and variants and the like. These materials are generally lighter materials than metal materials and have a hard surface which deform and/or break up impacting ballistic projectiles similar to metal but generally does not perform as well as metal with respect to repeat impacts in a localized area and generally do perform as well as a metal counterpart with respect to blunt trauma.
[0035] Armor plates 16 that are constructed of fabric are generally softer and do not perform as well on blunt trauma. These fabric armor plates 16 are often constructed of aramid woven fibers or similar high strength fibers such as those made of ultra-high molecular weight polyethylene or other materials. In fabric applications, because of their softer construction, sheets of metal or ultra-high molecular weight polyethylene, carbon fiber, glass fiber and/or quartz fiber based materials are also employed to provide stiffness and some trauma protection.
[0036] In other constructions of armor plate 16, plastic may be employed in layers such as those constructed of ultra-high molecular weight polyethylene. Additional constructions may include composite materials that include high strength fibers and epoxy based or various other resins used in composite construction can also be employed in the construction of armor plates 16. Other materials that may be used include the application of carbon nanotube, nanocomposite materials and grapheme, as well as others.
[0037] The thickness of armor plate 16 can vary as needed based on the materials used and ballistic resistance needed. In application with concealed armor, armor plate 16 generally does not exceed one quarter inch (0.25 in.) in thickness, however, the thickness can exceed this amount and is constructed as determined by the fabricator for the ballistic protection intended. In tactical body armor the thickness of armor plate 16 is generally not in excess of one half inch (0.50 in.) in thickness and again the thickness can exceed this amount and is constructed as determined by the fabricator for the ballistic protection intended.
[0038] Armor plate 16 for either first or second example 10 and 10 has solid foam 14 positioned on opposing sides of armor plate 16 as seen for example in
[0039] In first example of armor plate assembly 10, layers 20 and 22 of solid foam are heated in preparation of compression molding and armor plate 16 is positioned between layers 20 and 22 of solid foam 14 and this layered assembly is positioned within a compression mold. Layers 20 and 22 and armor plate 16 are pressed together molding solid foam 14 to encapsulate armor plate 16 with layers 20 and 22 of solid foam 14. Solid foam 14 is heated to facilitate securement and assembly of the substrates and to facilitate the deforming and molding of the solid foam into the desired shape closely fitting about armor plate 16 with the application of the compressive force by the compression mold. In some examples of use of polyethylene low density cross linked solid foam the foam can be heated to a temperature of approximately three hundred degrees Fahrenheit (plus or minus) (+or 300 F.) for making the foam pliable for the compression molding. The heat and compressive force applied will be optimally set based on factors such as the chemical composition of the solid foam selected, the density thereof and the thickness employed.
[0040] In the instance of first example of armor plate assembly 10, layers 20 and 22 of solid foam 14, based on the chemical composition, density and thickness of the solid foam 14 sufficient heat will be imparted to the solid foam 14 and a compression force will be employed to compress and mold solid foam 14 about armor plate 16 and bond solid foam 14 to armor plate 16. Portions of layers 20 and 22 which extend beyond and about a perimeter P, as seen for example in
[0041] This is similarly the case for assembling second example of armor plate assembly 10 as shown in
[0042] As seen in
[0043] Solid foam 14 encapsulates armor plate 16, as mentioned above, in both examples of ballistic resistant armor plate assemblies 10 and 10 shown in
[0044] For first and second examples of armor plate assemblies 10 and 10 discussed above, solid foam 14 is heated to a temperature for the material selected which will permit compression molding to encapsulate armor plate 16. In the above discussed examples of solid foam 14, adequate heat will be applied and compressive forces with a compression mold to fuse together portions of layers 20 and 22 which extend beyond perimeter P of armor plate 16. Heating and compressive force will be applied to bond layers 20 and 22 to armor plate 16 and to mold solid foam 14 about armor plate 16. In the second example 10 sufficient heat and compressive force will be applied to also laminate fabric 18 to layers 20 and 22 of solid foam 14.
[0045] With respect to fabric 18, this fabric can be one of many types of fabrics. Fabric 18 can be woven or nonwoven or a combination of these configurations. Additionally, fabric 18 can include a plurality of plies of the same or of different materials. In this example fabric 18 includes a woven fabric made of nylon having a denier of 500 and manufactured by Tweave Inc. of Norton, Mass. The material referred to herein as Tweave, a trademark of Tweave, Inc., is composed of a Nylon/Spandex blend and having a fabric weight of 6.5 ounces per square yard; 24-30% stretch in warp direction; 23-29% stretch in fill direction; Class 5 abrasion resistant and 100% spray rating for water repellency. The material provides, an abrasion resistant surface protecting underlying solid foam 14 and provides a friction surface for gripping and handling of second armor plate assembly 10. Fabric 18 is generally tear resistant as well so as to sustain its protective performance. Fabric 18 can be selected from a wide range of other fabrics such as for example at least one of nylon cordura, chlorofulthonated polyethylene, nylon polyester blend, cotton, cotton blend, spandex, fiberglass, carbon fiber, acrylics or polypropylene or others.
[0046] A third example of armor plate assembly 10 is shown in
[0047] Not all substrates of the assembly may need an adhesive layer, whether originating as a film or as an applied adhesive, such as for example where at least one of the substrates that adjoins another would have sufficient adhesive qualities such that a layer of adhesive film or an applied adhesive is not needed.
[0048] In the present example, these adhesive layers can be selected for optimal securement of adjoining components of fabric 18, layers 20 and 22 of solid foam 14, and armor plate 16 as seen in
[0049] Examples of such adhesive film layer includes a film layer selected from a variety of thermoplastic polymers such as polyethylene, polypropylene, polystyrene and acrylics or from a variety of thermoset polymers such as vinyl esters, phenolic, polyimides, polyurethane and epoxy resins. Examples of the applied adhesives have been mentioned above.
[0050] Each adhesive film layer is generally coextensive in size of the adjoining component of the assembly the film layer is to secure on each of the strike side and the back side of the assembly, as seen in
[0051] Further included is a method of assembling a ballistic resistant armor plate assembly 10 includes the step of positioning solid foam 20 in overlying relationship to strike side S of an armor plate 16 and positioning solid foam 22 in overlying relationship to a back side B of armor plate 16 such that a portion of solid foam 20 is in overlying relationship to strike side S of the armor plate 16 and extends beyond a perimeter P of armor plate 16 and a portion of solid foam 22 in overlying relationship to back side B of armor plate 16 extends beyond perimeter P of armor plate 16. The method further includes heating and compressing solid foam 20 in overlying relationship to strike side S of armor plate 16 and heating and compressing solid foam 22 in overlying relationship to back side B of armor plate 16.
[0052] The method further includes a step of positioning a fabric 18 in overlying relationship to solid foam 22 positioned in overlying relationship to strike side S of armor plate 16 and a step of positioning fabric 18 in overlying relationship to solid foam 22 positioned in overlying relationship to back side B of armor plate 16.
[0053] The step of positioning further includes positioning one of an adhesive layer or an applied adhesive between one of: fabric 18 and the solid foam 20 in overlying relationship to strike side S armor plate 16; solid foam 20 in overlying relationship to strike side S of armor plate 16; fabric 18 and solid foam 22 in overlying relationship to back side B of armor plate 16; or solid foam 22 in overlying relationship to back side B of armor plate 16.
[0054] As mentioned above and seen in
[0055] Similarly as seen in
[0056] Examples of the ballistic resistant body armor plate assemblies, but are not limited to these example assemblies with respect to this disclosure, include the following described examples. An example of a first assembly 10 includes armor plate 16 constructed of a three thousand denier (3000 den.) aramid thermoplastic system encapsulated with layers 20 and 22 of solid foam 14 composed of a low density cross linked polyethylene of a four (4) pound per cubic foot density. In one construction the woven aramid is in eight (8) plies. In a different construction the woven aramid is in twelve (12) plies. An example of a second assembly 10 includes armor plate 16 constructed of a three thousand denier (3000 den.) aramid thermoplastic system encapsulated with layers 20 and 22 of solid foam 14 composed of a low density cross linked polyethylene of a four (4) pound per cubic foot density. In one construction the woven aramid is in eight (8) plies. In a different construction the woven aramid is in twelve (12) plies. The fabric 18 laminated to layers 20 and 22 includes a five hundred denier (500 den.) nylon construction as discussed above for Tweave.
[0057] An example of a third assembly 10 includes armor plate 16 constructed of a three thousand denier (3000 den.) aramid thermoplastic system encapsulated with layers 20 and 22 of solid foam 14 composed of a low density cross linked polyethylene of a four (4) pound per cubic foot density. Layers 20 and 22 of solid foam 14 includes a low density cross linked polyethylene of a four (4) pound per cubic foot density. The fabric 18 includes a five hundred denier (500 den.) nylon construction as discussed above for Tweave. The adhesive films 24, 26, 28 and 30 are composed of thermoplastic polyethylene.
[0058] Another example of ballistic resistant body armor plate assembly includes the following layers within the assembly which includes a ballistic plate 16 of ceramic composition encapsulated in layers 20 and 22 of solid foam 14 of low density cross linked polyethylene. The assembly from the strike face side to the back side includes fabric 18 of Tweave; (0.125 inches) thick of low density polyethylene cross linked solid foam 14 layer 20; armor plate 16 constructed from an assembly of one layer of S2 (grade of fiber for) glass fabric with epoxy resin, 0.20 inches thick of silica carbide ceramic, one layer of S2 (grade of fiber for) glass fabric with epoxy resin and 0.25 thick consolidated UHMWPE; one layer of 0.20 inches thickness of expanded polyethylene non-cross lined solid foam 14 layer 22; polyethylene adhesive film; and fabric 18 of Tweave. In this example, with the outer layer of armor plate 16 assembly having a sufficient adhesive quality, this example does not require an adhesive film or an applied adhesive positioned between armor plate 16 assembly and layer 20 of solid foam 14 and does not require any adhesive film or applied adhesive between armor plate 16 assembly and layer 22 of solid foam 14.
