Definitions

  • This invention relates to the ceramic armor component field.
  • Ceramic armor is typically used for body armor and for the protection of different types of vehicles, such as various types of land vehicles, ships, and aircraft.
  • a ceramic armor is made of a ceramic tile and composite material as backing.
  • ceramic tiles are adhesively secured to a substrate then encapsulated in an outer cover. These substrate and cover represent the backing composite material.
  • the ceramic 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.
  • the function of the ceramic layer is to break the bullets while the function of the composite backing is to hold the ceramic in places during the impact and to catch the fragments produced during the impact and dissipate their mechanical energy by a plastic deformation.
  • a very important characteristic of ceramic component armors is their ability to defeat multiple shots within a relatively small area.
  • the challenge in developing multi-hit ceramic composite armor is to control the damage of the armor structure after the impact in its proximity.
  • metal armor have inherently this characteristic, that is related to the metal ductility and ability to withstand plastic deformation, in ceramic armor components it must be addressed by an appropriate design of the armor components.
  • the damage produced in ceramic hard face components by projectile impact can be classified into (1) a comminution zone of highly pulverized material in the shape of a conoid under the incident projectile footprint,
  • the most common approach to increase the multihit capability of a ceramic composite armor is the use of ceramic tiles mosaics.
  • the physical separation between the tiles in the mosaic constitute a barrier to the propagation of the ceramic damage that occur during the impact.
  • the area of the ceramic strike face damaged by an impact is limited to the size of tile, or maximum to a portion of two if the impact occurs across the junction.
  • FIG. 1 ( a - b ) schematic representation of a ceramic tile according to this invention and a perpendicular section respectively.
  • FIG. 2 ( a - c ) details of channels realization in section
  • FIG. 3 ( a - e ) different realizations of the invention in which channels are disposed according to various geometries.
  • ceramic tiles for armors according to the invention are standard tiles ( 10 ) with channels ( 11 ) joining the opposite surfaces.
  • Tiles can have smooth and continuous borders or they can present ( 12 ) cavities represented by part of the channels ( 11 ) (preferably an half of total number as shown in FIG. 1 ).
  • Channels can be simple holes or hollow tubes placed in the body of the tile, constituting an open channel on both opposite surfaces.
  • Channels can have circular or polygonal section (for example, square, hexagonal, triangular, pentagonal) and can be perpendicularly disposed or inclined across the tiles surfaces.
  • channels internal dimensions should be between 0.5 and 5 mm.
  • channels could have a rectangular (FIG. 1 - a ), conic or biconic inner section, or be tapered off at one or the other or both ends ( FIG. 2 a - c ).
  • channels according to this invention considerably increase the multi-hit resistance, because shock waves propagation through the tile is stopped thanks to these diffraction lines inside the material itself.
  • the internal volume of the channels could be streamlined with materials that have an acoustic impendence, as for example alumina, zirconia, boron carbide or silicon carbide, silicon nitride, silica or mixture thereof, metals as copper, iron, steel and wolfram, different from the ceramic one, such as plastic materials (low acoustic impendence) or metallic/ceramic materials (high acoustic impendence).
  • plastic materials low acoustic impendence
  • metallic/ceramic materials high acoustic impendence
  • a further advantage of this invention is the weight reduction obtained by the presence of channels. This characteristic is very important because ballistic armors always represent a parasitic weight.
  • This invention involves tiles commonly made of ceramic materials such as: aluminum oxide, boron carbide, silicon carbide, glass ceramic materials, titanium diboride, or their mixtures and other similar products. They are manufactured following well known processes (using moulds or by extrusion).
  • the channels related to this invention are easily realized, by extrusion or by cold pressing using moulds with punch matrixes. These are the most common forming techniques used for mass production.
  • Possible streamline can be easily conducted during the manufacturing process of the ballistic panel or as an intermediate phase after the ceramic tile production. While filling of channels can be made successively, after the monolithic tile production and can obtained by fusion of plastic, metal or vitreous materials.
  • channels can be filled with powder that are sintered with an additional thermal treatment.
  • a further producing system consists of the co-shaping of two ceramic powders or a ceramic and metal one. Recently, systems of co-injection of different ceramic materials have been set up, in order to obtain composite ceramic products.
  • Another manufacturing system consists of the filling of a mould with two powders, that are the matrix and the channels, with the second one placed upright resembling channels shape.
  • Multiple components proportioning systems are well known and used in many technical ceramics applications.
  • channels create 2-10 mm discontinuities (channels diameter 1 mm, at a distance of 2 mm from each other) while slots create discontinuities of 20-50 mm.
  • a higher discontinuity density heightens the effects and improves the capacity of arresting of the fracture propagation.
  • channels permits the mechanical connection of the two parts of the ballistic inserts making the whole structure more strong and firm. While, there is no possibility to reach this purpose with tiles with slots, because such slots should not have a diameter of more than 0.5 mm.
  • the high discontinuity density enhances the multi-hit power, in fact near to the impact point there will always be conjunction points between the two parts of the composite panel (front and rear). This increases the ceramic confinement. It is well known in literature that the ceramic confinement improves the multi-hit characteristics.
  • Channels can be distributed in the ceramic body of the tiles in a casual way or according to repeated geometric drawings, such as: parallel lines equidistant or at different distances from each other. Channels can be disposed in squares, hexagons, star-like shape etc. as schematically shown in FIG. 3 .
