Definitions

  • the present invention generally provides improved systems, compositions and methods for substantially transparent/translucent, breakage-resistant composite structures; and more particularly, representative and exemplary embodiments of the present invention generally relate to bullet-resistant windows and/or ballistic laminate materials.
  • various exemplary embodiments of the present invention relate to ballistic glass and transparent armor useful in military and security vehicle applications.
  • Still other representative embodiments of the present invention relate to architectural and design elements for security purposes in hostile environments. BACKGROUND
  • the various layers used in the composite may be chosen for their different projectile resistance characteristics and functions.
  • glass layers are hard and thus readily erode bullets and are highly abrasion resistant; however, glass layers are also brittle, which generally causes any glass layers opposite a penetration threat to spall, which in turn creates shrapnel fragments.
  • the shrapnel may produce numerous projectiles on the interior surface of the vehicle.
  • the resulting spall (or fragments) may in fact be more dangerous than the original penetrator.
  • Plastic material layers used as part of a composite sandwich provide a means to introduce flexibility into the transparent armor composite. The addition of one more plastic layers to the composite changes the failure mode of the transparent armor so it fails in a more ductile manner rather than spalling.
  • Acrylic-, polyurethane- and polycarbonate-based materials are among the plastic materials which have been shown to have utility in producing transparent armor composites.
  • polycarbonate One class of plastics that has proven both useful and reliable in constructing transparent armor composites and architectural bandit type barriers is polycarbonate.
  • Polycarbonate has demonstrated superior characteristics in terms of providing overall protection because it demonstrates the highest spread between brittleness transition temperature and heat distortion temperature. For this reason, polycarbonates are generally preferred materials in transparent armor composites.
  • polycarbonate and the other plastic materials are also soft and easily abraded by the action of dirt and dust.
  • polycarbonates are frequently adversely affected by solvents and cleaning solutions when used to remove dirt. Thus, the cleaning of surface dirt and grime will inevitably cause scratching. This causes the optical properties to be adversely effected. Scratching can cause the transparency of the armor composite to substantially degrade in under one year. The substantial degradation of transparency generally necessitates replacement of the composite. Since transparent armor composites are expensive, frequent replacement creates a substantial financial burden on maintenance budgets.

  • the bonding layer may be composed of material having high elongation characteristics, or any other suitable material capable of mitigating temperature-rated expansion differentials associated with the kinetic layer 100 and the facing layer 110. If the bonding layer does not have suitable elongation characteristics over a given temperature range, the bonding layer may become damaged should the first and second layers expand or contract.
  • the thickness ratio of the kinetic layer 100 ⁇ e.g., polymeric material) to the facing layer 110 ⁇ e.g., glass material) should be at least approximately unity. It will be appreciated, however, that various other thickness ratios may be alternatively, conjunctively or sequentially employed to achieve a substantially similar result. It will also be appreciated that different thickness ratios will produce different armor characteristics that are uniquely adapted for particular threats or operating environments.

  • the facing material may be almost any composition, such as, for example: soda lime; crown; borosilicate; aluminum oxynitride; sapphire; etc. Any glass material, whether now known or otherwise hereafter described in the art, may be alternatively, conjunctively or sequentially employed in order to achieve a substantially similar result.
  • projectile may refer to any object that may strike the surface of a optically transmissive armor assembly. These may include projectiles used to attack the integrity of the optically transmissive armor such as ballistic items (bullets, shrapnel, thrown objects such as bricks, stones and other similar objects) and self-propelled items (such as RPGs, missiles, and other rocket- like objects). Projectiles may also include objects used to directly strike the surface of the optically transmissive armor, such as, for example: bricks, bats, metal objects, stones, wooden clubs, etc. Finally, projectiles may also include other objects that come into contact with the surface of the optically transmissive armor. For example, if the optically transmissive armor is used as part of a vehicle and that vehicle were to be involved in an accident, portions of other vehicles, the road, buildings or other objects may strike the surface of the optically transmissive armor.

  • the glass material generally serves to merely blunt or otherwise deform a projectile that is striking its surface, as opposed to depleting a substantial fraction of the kinetic energy of the projectile.
  • glass facing layers in accordance with the instant invention may be relatively thin compared to those of the conventional art.
  • a thinner layer of glass material is preferable because it significantly reduces the weight of the armor assembly without substantially decreasing penetration impedance, and simultaneously provides improved optical characteristics and retention of localized structural integrity after the armor assembly is struck by a projectile.
  • the present invention weighs considerably less than that of conventional transparent armor alternatives. Optical clarity after a projectile strike (i.e., hit proximity performance) is also improved. As the thickness of the glass facing material decreases, the damaged area (i.e., hit radius) and glass loss also decreases. For example, the glass loss in a 1/8" facing is only about 1" diameter; however, with 1/4" glass, this area extends out to roughly 3" in diameter or greater. Accordingly, after a hit on a thinner layer of glass, less of the material's optical characteristics will have been compromised.

  • Second hit capability i.e., the ability of the optically transmissive armor assembly to stop a projectile that strikes its surface in close proximity to the location of a prior hit
  • Second hit capability is substantially improved due to the minimized glass loss that results from use of thinner layers of glass facing.
  • the glass loss area after a first hit is greatly weakened and will not provide much protection against a second hit. Accordingly, it is preferable to employ a thinner layer of glass material in the facing layer 110, thereby minimizing the amount of glass loss.

  • the index of refraction match can be nearly perfect (within a given temperature range). This limit of temperature range may preclude the use of sphere tile elements, but flat mosaics may be useful under similar conditions.
