Description

    TECHNICAL FIELD AND BACKGROUND OF THE INVENTION
  • This invention relates to a hard armor composite, and more particularly to an improved small arms protection insert (SAPI) applicable for protecting against multiple small arms bullets and projectiles. In a preferred embodiment, the invention incorporates a rigid ceramic plate and a ballistic fabric backing.
  • Ceramic armor is typically used for body armor and for the outer coverings of different types of vehicles, such as various types of land vehicles, ships, and aircraft. Typically, ceramic tiles are adhesively secured to a substrate then encapsulated in an outer cover. The armor system is then attached to a vehicle by a variety of means or merely placed in a fabric pocket, as in the case of body armor. An inherent problem in the prior art is that ceramic armor is configured for a fixed level of protection against a single ballistic threat.
  • The current SAPI incorporates ceramic and an extended chain polyethylene fiber base material known in the industry as “Spectra Unidirectional Cross Plied”. This material contains fibers produced by Honeywell International, Inc., and distributed under the brand Spectra Shield® PCR and Spectra Shield® Plus PCR. The current SAPI has been accepted for application by the United States military. However, due to limited production and sources of Spectra Shield® PCR and Spectra Shield® Plus PCR, a need exists for an alternative acceptable ballistic fabric construction which can be readily obtained from multiple sources.
  • A further need exists for a reduced-weight fabric construction which offers at least comparable and preferably increased ballistic performance. Military specifications call for a SAPI which meets predetermined maximum weight and performance criteria. The ballistic fabric used in the current SAPI has a denier per filament (dpf) ratio of 5.4—denier being defined as a weight measurement in grams per 9000 meter of fiber length; and denier per filament (dpf) defined as denier divided by the number of filaments in a fiber bundle. For an example, Spectra Shield® PCR comprises a nominal 1300 denier fiber with 240 filaments (or, 5.4 dpf). The present invention uses a lower dpf fiber which meets or exceeds the required ballistic performance criteria. The reduced fiber weight enables use of a heavier, less costly ceramic in a SAPI which further satisfies the required maximum weight criteria.

    • BRIEF DESCRIPTION OF THE DRAWINGS
  • Some of the objects of the invention have been set forth above. Other objects and advantages of the invention will appear as the description proceeds when taken in conjunction with the following drawings, in which:
  • FIG. 1 is a perspective view of a hard armor composite according to one preferred embodiment of the present invention, and showing a portion of the outer cover torn away to expose the interior elements;
  • FIG. 2 is a cross-sectional view of the hard armor composite taken substantially along line 2-2 of FIG. 1; and
  • FIG. 3 is a perspective view of a hard armor composite according to a second preferred embodiment of the present invention, and showing a portion of the outer cover torn away.
    • DESCRIPTION OF THE PREFERRED EMBODIMENT AND BEST MODE
  • Referring now specifically to the drawings, a hard armor composite according to the present invention is illustrated in FIG. 1, and shown generally at reference numeral 10. In one application, the composite 10 is a small arms protection insert (SAPI) designed to protect against multiple small arms bullets and projectiles. The composite 10 is constructed according to United States military specifications, CO/PD 00-03D dated Jan. 13, 2003, in sizes X-small, small, medium, large, and X-large ranging in weight from 2.85 to 5.35 pounds. All SAPI sizes have a uniform nominal areal density of 5.1 pounds per square foot or less. The dimensional measurements are indicated in Drawing Nos. 2-6-265, 2-6-266, 2-6-267, 2-6-268, and 2-6-269 of CO/PD 00-03D. The entire subject matter of CO/PD 00-03D, including text, drawings, tables, and charts, is incorporated herein by reference.
  • As shown in FIGS. 1 and 2, the hard armor composite (SAPI) 10 comprises a ceramic plate 11 and ballistic fabric backing 12 encased in an outer cover 14. The cover 14 may be formed of a single knit material, such as nylon fabric, or may be a rubberized coating formed by dipping, or may be a combination of fabric, rigid plastic, and foam or honeycomb structure that protects the ceramic from wear-and-tear, and which contains ceramic particles on impact as appropriate. Preferably, the cover 14 includes a bake panel 15 that either partially or completely covers the rear surface of the composite 10.
  • The ceramic plate 11 is a rigid facing defining a first level of hard armor protection in the composite SAPI. The ceramic plate 11 may include a number of individual elements, such as ceramic tiles, or may be a singular (monolithic) structure that is either flat or molded to a desired shape. The plate 11 is made of any suitable ceramic material, such as boron carbide, silicon carbide, high purity aluminum oxide, titanium diboride, aluminum nitride or silicon nitride or sintered silicon carbide and sintered silicon nitride ceramics. Alternatively, a ceramic matrix composite or metal matrix composite containing any of above-mentioned ceramics could be used. Although ceramic thickness may be varied to suit the specific SAPI need, the preferred ceramic arrangement ranges from 0.080-inches to 0.40-inches in thickness.
  • The fabric backing 12 is bonded or otherwise secured, either directly or indirectly, to the ceramic plate 11, and provides a second level of protection against ballistic penetration. Preferably, the ceramic plate 11 and fabric backing 12 are joined together by a layer 16 of adhesive, such as a thermoplastic or thermoset polymer, an elastomeric resin matrix, or a film, such as epoxy, polyurethane, polysulfide, polyolefin, phenolic, polyester, vinyl ester, polyvinyl butyral.
  • The backing 12 is constructed of bundled, high-performance, low denier per filament (dpf) fibers comprising any one or a combination of aramid, extended chain ultra-high molecular weight polyethylene (UHMWPE), poly {p-phenylene-2,6-benzobisoxazole} (PBO), and poly {diimidazo pyridinylene (dihydroxy) phenylene} (M5). Each of these fibers has a tensile strength greater than 7 grams per denier. Suitable commercial fibers include: Twaron® micro-denier fiber of less than nominal 1000 denier and 1.5 dpf or lower; Spectra Shield® PCR fiber of less than nominal 1300 denier and less than 5.4 dpf; Dyneema® UD (unidirectional) fiber of nominal 1600 denier and 2.0 dpf or lower; PBO Zylon® fiber of nominal 1000 or 500 denier and 1.5 dpf or lower; and aramid Kevlar® fiber of nominal 1500 denier and 1.5 dpf. The fibers are preferably HM (high modulus) grade with low moisture content. The preferred embodiment utilizes high-performance fibers having less than 5.4 dpf, and more preferably, less than 2.0 dpf, and most preferably, less than 1.5 dpf.
  • The fibers are incorporated in multiple, stacked layers comprising knit, woven, or non-woven fabrics, non-woven or woven unidirectional tapes, felts, and three-dimensional structures. The stacked layers are laminated under heat and pressure together with any of a variety of polymer compounds to create a dense, rigid, unitary ballistic structure ranging in thickness from 0.130-inches to 0.350-inches. Lamination occurs via autoclave, press molding, a resin transfer mold, and/or an oven with vacuum pressure. According to one embodiment, the fabric backing 12 is further encased in a polymer matrix or film, specifically, a thermoplastic or thermoset matrix. The matrix may include any suitable polymer resin or film, such as phenolic, polysulfide, phenolic, polyvinyl butyral rubber blends, polyester, vinyl ester, polyurethane, and polyolefin resins or combinations thereof. When using a polymer resin matrix, the preferred resin content ranges from fifteen to twenty-four percent by weight.
  • In an alternate embodiment shown in FIG. 3, the hard armor composite (SAPI) 20 includes an arrangement of individual ceramic tiles 21 defining a rigid facing, an adhesive layer 22, and a ballistic fabric backing 23. The ceramic tiles 21 can be square or otherwise shaped to suit the dimensional needs of a particular application. The fabric backing 23 incorporates high-performance, low dpf fibers, and is constructed in a manner identical to that described above. The adhesive layer 22 joins the tile elements and fabric backing together to form a unitary ballistic composite.
  • In each of the above embodiments, the hard armor composite 10, 20 forms a SAPI which meets or exceeds the ballistic performance criteria outlined in CO/PD 00-03D. Specifically, Section 3.9.3 of CO/PD 00-03D states that the SAPI when inserted in a nylon cordura carrier will be capable of defeating three impacts (2 impacts at 0-degrees obliquity and 1 impact at 30-degrees obliquity) from each of the following threats:
  • a. NATO 7.62×51 mm—80 Ball at 2,750+50 feet per second.
  • b. Soviet 7.62 mm×54R Ball Type LPS at 2,300+50 feet per second.
  • c. U.S. 5.56 mm M855 Ball at 3,250+50 feet per second.
  • The use of a ballistic fabric backing incorporating high-performance, low dpf fibers not only reduces the overall weight of the composite, but offers increased ballistic performance as compared relatively high dpf fibers. The current commercial SAPI incorporates high-performance fibers with a 5.4 dpf. The V50 ballistic performance of fabric constructed of this fiber is compared in the table below with fabric of lower dpf fibers.
  • V50 data with 9 mm 124 grams per Mil-STD 662.
