Definitions

  • This invention relates to hybrid structures incorporating a multiplicity of materials and topological design that are able to support structural loads while effectively impeding the penetration of projectiles and mitigating the distributed impulse of a nearby explosion. More particularly, this invention relates to methods and systems that use a combination of high performance metals shaped in the form of sandwich panels, ceramic tiles and prismatic structures and high-tensile strength fibers mitigate the impulse loadings due to a nearby explosion and or high velocity projectiles.
  • Composite armors that exploit ceramic materials such as alumina, boron carbide, silicon carbide, and titanium diboride, can all provide a much lighter mass solution to the defeat of a projectile, especially those that very hard and designed to penetrate conventional metal systems. Unfortunately, these ceramic-armors often crack while dissipating the energy of an explosion or a ballistic impact, thereby weakening the armor against subsequent impacts in the same region.
  • ceramic materials such as alumina, boron carbide, silicon carbide, and titanium diboride
  • Modern armor uses a combination of metals, ceramics and ballistic fiber-based fabrics or fiber reinforced composites to further improve the resistance to projectile impact.
  • High-performance fabrics have a strength-to-weight ratio several times higher than steel.
  • One of the most popular fabrics is composed of para-aramid fibers (Kevlar ® by DuPont and Twaron® by Teijin Aramid), however, other commonly used high-performance fabrics are composed of ultra-high molecular-weight polyethylene (Spectra ® by Honeywell and
  • Dyneema® by DSM polyamides (Nylon® by DuPont), PBO (Zylon® by Toyobo), M5® (DuPont) and carbon ( ⁇ series by Hexcel and T series by Toray) fibers.
  • a fabric hit by a projectile can rapidly slow or decelerate the projectile by acting as a web of high tensile fibers, pulling on the projectile and forcing a rapid deceleration.
  • such fabrics can not only provide a stopping measure for projectiles, but also helps retain the original shape of the armor components.
  • a spall shield a layer of a polymer fiber fabric or composite usually positioned at the rear of the armor to catch material ejected from the armor during an impact event.
  • the spall shield helps prevent the ejection of high velocity fragments of either the ceramic layer or the projectile after projectile contact.
  • One solution creates a large aramid fabric compressed between plastic sheets and secured in place to the surrounding structure, such as a vest or panel wall.
  • Another solution encapsulates a ceramic structure in organic compounds, then creates a backing structure of Kevlar® or Dyneema® (see U.S. Patent 7,478,579). Both solutions can help maintain the form of impacted ceramics.
  • these ceramic armor systems offer a significant advantage over previous armor systems in maintaining the shape of ceramic components, there exists a need for armor systems capable of stopping projectiles of even greater velocities, while maintaining the shapes of ceramic components and a low weight. It is further important to recognize that none of these solutions is designed to carry structural load or mitigate the effects of a nearby explosion and their ballistic integrity can be seriously diminished when exposed to explosive loadings or severe nearby impacts.
  • An armor system for decelerating a projectile is disclosed.
  • the system is formed of a number of tile or prismatic structures arranged in a grid structure.
  • a tile is wrapped in multiple layers of a high-performance fabric from multiple directions.
  • the tiles preferably are designed as anti-projectile tiles, and can be metallic, ceramic, or a metal- ceramic composite.
  • An example of a metal-ceramic hybrid is a metallic frame with ceramic inserts.
  • After selection of the tile it is continuously wrapped in multiple layers of fabrics such as Kevlar®, Twaron®, Dyneema®, Spectra®, Zylon®, M5®, Nylon® and IM- or T- series carbon fibers.
  • the invention specifically calls for a single sheet used for the wrapping so as to minimize free ends to sheet.
  • consolidation of the wrapped tile occurs, finishing the wrapped tile into a compact tile without loose fabrics.
  • the method of consolidation varies according to the fabric and/ or tile used, but may include hot pressing or autoclave processing. These hot presses or autoclaves can ensure any adhesive/ resin sets properly, and creates a compact confined product.
  • Further aspects can include implementation of the wrapped tile into an overall armor design, including additional structures for maintaining armor shape after projectile impact. These additional structures can include a spall shield, a lattice structure for holding tiles, blast absorbing panels and a back panel. All of these structures can further aid in projectile deceleration.
  • a key aspect of the invention is the use of space behind the fabric wrapped tile or prism layer.
  • FIG. 1 illustrates an exemplary embodiment of wrapping a tile in fabrics, with a consolidated view
  • FIGS. 2A through 2C are cross-sectional views of an exemplary tile before being wrapped with aramid fabric, after being wrapped with aramid fabric, and after being impacted by a projectile;

  • aramid fabrics are woven or layered from Kevlar®, Twaron®, Dyneema®, Spectra®, Zylon®, M5®, Nylon® and IM- or T-series carbon fibers, which all have high- tensile strength to weight ratios several times greater than steel.
  • the number of fabric layers wrapped around a ballistic tile can vary, though in a preferred embodiment application of the fabric is continuous and positioned such that the fabric envelopes the entire ballistic tile.
  • the term "high-performance fabric” shall refer to any such fabric that is suitable for use as anti-ballistic material.
  • the number of units or rolls of fabric can vary. In most embodiments, the number of rolls used equals the number of sets of parallel sides. For example, a square has 2 sets of parallel sides, and thus uses two rolls. A hexagon would use 3 rolls, an octagon 4, and so on. Generally these separate rolls of fabric will be applied such that fabric covers the entire ballistic tile, though on occasion there may be incentive to expose a piece of the panel or have certain sections of the panel less wrapped than other sections. In one embodiment, the rolls will be applied sequentially, each roll forming a layer until all the rolls have formed layers, and repeating this sequential process until wrapping completes. In another embodiment, one roll wraps around the tile until complete, followed by a second roll, and so on until all rolls have been used.
  • Consolidation can be performed using hot presses to remove any additional air in the fabric layering and seal the layers together. Consolidation can also be performed using autoclaves, which can cure any interior adhesives used, such as those used for adhering ceramics to metal tile frames or for adhering fabric layers to one another.
  • One purpose of consolidation is to make a smooth, compact, finished product which can be used without likelihood of unraveling.
  • An exemplary advantage of wrapping tile in fabric is that upon impact of a projectile, the fibers of the fabric receive tension from larger surface areas created by material in the interior of the tile. This increased surface area creates additional stopping power, particularly when the projectile fragments.
  • a projectile with sufficient kinetic energy will, upon entering a ceramic, crack and push the ceramic in a distal direction and angles to the distal direction from the projectile.
  • the tremendous kinetic energy also creates a void in the wake of a projectile expanding, referred to as "mushrooming," of the ceramic and creating greater tension in the fibers.
  • the fragmented and dispersed load from the originally intact projectile involves a larger amount of the fabric wrapping.
  • Exemplary implementations may include a wrapped tile being placed within a cavity of a vest for use as individual body armor, or a wrapped tile being placed into a lattice with other anti-projectile measures, such as a spall shield, a composite back panel, or a blast mitigation layer.
  • An implementation with a lattice could, in some instances, be too bulky for use in an individual's body armor, but could be implemented into building or vehicular systems. The disclosure now turns to FIG. 1.
  • FIG. 1 illustrates an exemplary embodiment 100.
  • the ballistic tile 102 shown will be wrapped in aramid fabric 104a, 104b.
  • the ballistic tile can be of any material desirable to promote deceleration of projectiles, such as metal plates, ceramic tiles, or composite tiles.
  • the ballistic tile 102 depicts an Aluminum 6061 -T6 frame with Alumina (A1 2 0 3 ) ceramic inserts, but can be replaced with a steel plate, or a purely ceramic material.
  • the tile 102 can be made of at least one of aluminum, steel, magnesium, titanium, boron carbide, silicon carbide, aluminum oxide and cermets (metal matrix composites).
  • the fabrics 104a, 104b are shown in rolls, but can be any shape which allows the fabric to be continuously distributed when wrapping the ballistic tile 102. Because the ballistic tile 102 shown has four sides it has two sets of parallel sides: top and bottom, left and right. This results in two units of aramid fabric 104a, 104b to be used for wrapping the tile. If, however, one desired a tile with a hexagonal shape, three units could be used— one for each set of parallel edges. In another aspect, one could use four units or rolls of fabric on a square tile, one starting on each unique edge of the tile. Both the shape of the tile and the number of units of aramid fabric can be modified to the particular situation desired by a user.
  • the fibers 104a, 104b wrap around the ballistic tile 102. Wrapping occurs sequentially, as indicated by the arrows 106. In this example a first roll 104a would be wrapped around tile 102 in a first direction, followed by a second roll 104b wrapping around the tile 102 in a second direction perpendicular to the first direction. Each application of a roll 104a, 104b applies a single layer of fabric around the tile. This process continues until a desired number of layers has been applied to the tile. In a preferred embodiment, each roll of fabric applied to a square tile as shown in FIG. 1 would be applied eleven times, resulting in twenty-two total layers of aramid fabric around the tile.
  • a consolidated wrapped tile 112 of multiple layers will then have dimensions 108, 110 which can be used for calculation purposes when implementing the consolidated tile into projectile armor systems.
  • the consolidated tile 112 shown has markers for the corners. In certain embodiments corner pieces may be used for locking the tile into place. In other embodiments, the corners may be rounded and smooth. Here, corner pieces are shown to mark the edges of the consolidated units, aiding in distinguishing separate tiles when combined with other anti- projectile technology.
  • FIGS. 2a - 2c illustrate an exemplary side view of a composite ceramic tile before being wrapped 2a, after being wrapped but pre -impact 2b, and after impact 2c.
  • the composite ceramic tile has a metal frame 202 and ceramic inserts 204.
  • FIG. 2b shows the composite ceramic tile wrapped in fabrics 206. The number of layers may vary from that shown according to user needs.
  • FIG. 2c shows this same exemplary wrapped composite ceramic tile after impact from a projectile 216.
  • the projectile impacted and entered the wrapped tile at a location 208.
  • kinetic energy was dispersed such that matter not in the projectile's trajectory was pushed away, resulting in mushrooming 210.
  • the mushrooming pushes back on the wrapped fabrics, increasing the overall tension of the fabrics.
  • As the projectile continues through the tile it pushes matter into the fabric layers on the "exit side" of the wrapped tile. This creates additional tension in the fabrics resulting in a hoop stress 212 and 214 circulating the tile 112.
  • the projectile lacked sufficient kinetic energy to emerge from the wrapped tile the fabrics on the exit side of the tile will remain intact. In this case one may find the projectile 216, or its shattered pieces within the deformed tile. If the kinetic energy were sufficient the wrapped fabrics may also break. In considering the tension forces resisting against or pulling on the projectile as it impacts the wrapped tile, one must not forget that the tensile forces come from all sides as a consequence of fabric wrapping in multiple directions, not just those shown in the figures.

Abstract

Cette invention se rapporte à une structure multifonctionnelle permettant d'atténuer les effets des explosions et d'empêcher la pénétration de projectiles et qui est également très efficace pour supporter des charges structurelles (à savoir statiques). En enveloppant une tuile dans de multiples couches d'un tissu haute performance, lors de l'impact d'un projectile, des forces de traction supplémentaires sont créées, ce qui aide à la décélération du projectile. Avec des couches supplémentaires, les forces de traction aidant à la décélération du projectile augmentent, ce qui donne un panneau pare-balles destiné à être utilisé dans des systèmes de blindage/structurels multifonctions qui présentent un poids plus léger et une puissance d'arrêt plus grande que les systèmes d'armure classiques en plus de servir de pièce d'une structure permettant de supporter des charges statiques.
