Definitions

  • the invention relates to a composite armor plate for protection against projectiles with the features of the preamble of patent claim 1.
  • Composite armor plates which consist of a composite of several materials, are known per se. Frequently composite armor plates are constructed such that between two plate elements filling materials or filling elements are introduced, which are then encapsulated with a pourable mass.
  • DE 1 578 324 describes such a plate, wherein balls or cylinders made of a hard ceramic material are used as filling elements.
  • the cylinders are arranged in rows in the plate in several discontinuous layers or layers, ie their Longitudinal axes are substantially parallel to the plane of the plate and parallel to each other, wherein the cylinders of the one layer are arranged offset with respect to the cylinder of the other layer transversely to its longitudinal direction.
  • the cylinders are further spaced apart using a plurality of layers of spacer material such that each layer of spacer material is alternately wound over and under the cylinders in their respective locations.
  • the object of the invention is, starting from the prior art, to design a composite armor plate in such a way that it causes an increased protective effect with a small basis weight.
  • the composite armor plate according to the invention consists of at least one layer of rod-shaped elements.
  • any body is considered in which the ratio of total length to maximum diameter is at least 1.
  • the elements are not only in series next to each other, but are also arranged in the axial direction within a row of a layer behind the other.
  • the joints which arise due to the axially successive arrangement of the elements, arranged offset relative to the joints of at least one adjacent row in the axial direction.
  • the advantages of the invention will become apparent from the denomination of the elements, wherein the joints caused thereby are staggered, since thus the protection weakening caused by the joints is largely compensated by the adjacent elements.
  • the joints may be offset both with respect to the joints of an adjacent row of the same layer and with respect to the joints of an adjacent row of an adjacent layer.
  • the rod-shaped elements may be present in the composite armor plate.
  • the layers may be arranged such that the rod-shaped elements of a layer are offset relative to the rod-shaped elements of the adjacent layer in a direction perpendicular to the longitudinal axis of the rod-shaped elements.
  • the rod-shaped elements may have different cross-sections.
  • the plurality of rod-shaped elements may have as cross-section a shape similar to that of a circle or an ellipse or a section of such a shape.
  • the majority of the rod-shaped elements can have a polygon or a cutout of such a shape as a cross section.
  • the protective effect of the composite armor plate is the design of the end faces of the rod-shaped elements.
  • the end faces may be designed as a flat surface in a plurality of rod-shaped elements, which may be either perpendicular to the longitudinal axis of the rod-shaped elements or at an angle to this.
  • the end faces may also be executed concave, wherein advantageously the ratio of the maximum diameter to the radius of the face curvature is less than 0.6.
  • the plurality of rod-shaped elements may have at one end concavely curved end faces, in which the ratio of the maximum diameter to the radius of the face curvature is less than 0.6 and at the other end have corresponding convex end faces.
  • the plurality of rod-shaped elements may have conically outwardly directed end faces, the tips of which are rounded off or cut off.
  • the ratio of the radius of the rounded tip to the largest cross section may be less than 0.25.
  • the plurality of rod-shaped elements may have at one end conically outwardly directed end faces, the Tips are rounded or cut off and have at the other end corresponding, conically inwardly facing faces.
  • the ratio of the radius of the rounded tip to the largest cross section may be less than 0.25.
  • the plurality of rod-shaped elements may have end surfaces which are roughened or which are provided with structures which prevent a flat abutment of two opposite end faces.
  • shock-absorbing materials can be introduced, in particular in the form of films, threads or granules, in particular of metals, plastics, fiber materials or of elastomeric materials.
  • the composite armor plate When using the composite armor plate to protect against larger caliber, it may be appropriate to extend this shock absorption on the lateral surface and also introduce there between the rows of rod-shaped elements shock-absorbing materials, especially in the form of films or granules, in particular of metals, plastics, fiber materials or made of elastomeric materials.
  • the rod-shaped elements may further at least partially with at least one shock-absorbing coating, in particular of metals, plastics, fiber materials or of elastomeric mate- materials, be provided.
  • the rod-shaped elements can be surrounded by a potting compound, in particular the space between the rod-shaped elements can be filled with the potting compound, which is connected to at least one continuous outer outer layer.
  • the potting compound may be made of plastic, in particular of polyurethane, epoxy, polyester, rubber or other elastomeric material.
  • the backside of the composite armor plate may be made of layers that have shock absorbing properties and high tensile strength.
  • the composite armor plate may be self-supporting mounted in a frame construction on the object to be protected (e.g., a vehicle) or on a structural armor made of armor steel or light metal, where shock absorbing interlayers may be used, or air gaps may be provided between the structural shell and the armor plate.
  • a frame construction on the object to be protected (e.g., a vehicle) or on a structural armor made of armor steel or light metal, where shock absorbing interlayers may be used, or air gaps may be provided between the structural shell and the armor plate.
  • the composite armor plate can have layers or plate-shaped elements on the side facing and away from the projectile, between which the bar-shaped elements are arranged. It is also possible that the composite armor plate for weight reduction only on the side facing the projectile has a final layer or that the potting compound is open at least on one side of the composite armor plate, which may optionally be provided with a paint. At least one side, in particular the side facing away from the approaching projectile, may consist of at least one solid layer of fiber material, in particular of aramid, glass fiber, polyamide or carbon fiber, or of at least one soft shock absorbing layer, in particular of foams or of elastomeric mate- rials to be made.
  • the material of the rod-shaped elements is also of crucial importance for the protective effect of the composite armor plate.
  • at least one rod-shaped element of a ceramic material of alumina ceramic having an Al 2 O 3 content of 92-99.99%, of a high-hardness material, in particular boron carbide, silicon carbide, silicon nitrite or titanium triborate, or a hard metallic Material, in particular of hardened steel, aluminum, titanium or a sintered material consist.
  • the total length of the plurality of rod-shaped elements may be in the range of 13 mm to 300 mm. Furthermore, the plurality of rod-shaped elements may have a ratio of the total length to the maximum diameter, which is greater than 2.
