Definitions
- the invention relates to a composite armor element for the protection from projectiles with the features of the preamble of patent claim 1 and an active body element for introduction into a composite armor element with the features of the preamble of patent claim 34.
- Composite armor elements such as composite armor plates or composite armor mats, which consist of a composite of several materials, are known per se. Frequently composite armor elements are constructed such that filling materials or active bodies are introduced between two, for example, plate-shaped elements, which are then encapsulated with a pourable matrix material such as plastics or metals. The plates are often provided with finishing layers. The manufactured composite armor plates can be glued on the back with thick fiber composite layers and thus form self-supporting armor elements or they are attached to metallic vehicle housings such as a welded steel tub, whereby they reach the full protective effect together with the housing structure. It is also known to arrange shock-absorbing materials between the active bodies so that the active bodies do not adhere directly in a disadvantageous manner.
- DE 1 578 324 describes a composite armor plate, wherein single spheres or cylinders made of a hard ceramic material are used as the active body.
- the cylinders are arranged in rows in the plate in several discontinuous layers or layers, i. their longitudinal axes are substantially parallel to the plate plane and parallel to each other, wherein the cylinders of the one layer are arranged offset with respect to the cylinder of the other layer.
- 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.
- EP 1 071 916 B1 describes a composite armor plate with individual cylindrical ceramic active bodies, wherein the space between the active bodies is filled with form-fitting triangular or hexagonal intermediate space pellets.
- EP 1 363 101 A1 describes a composite armor plate, wherein the individual active bodies are provided with a belt in order to reduce the total weight of the plate.
- a disadvantage of the known plates that the production due to the large number of small active body and the introduction of shock-absorbing materials is complex and inaccurate.
- the invention has the object to improve the disadvantages mentioned.
- the invention solves the problem with the features of the characterizing part of patent claim 1 and with the features of the characterizing part of claim 34.
- Advantageous developments are part of the dependent claims.
- the individual active bodies of an active-body element can be made of high-hardness materials, in particular of ceramic, metal, sintered or fiber materials, with small dimensions with respect to the plate dimensions. They can be cylindrical, spherical or tetrahedral or rod-shaped with a polygonal cross-section. The faces may be straight, curved, conical, angular or oblique cut.
- the active bodies preferably have, at least partially, a ratio between height and maximum width extension that is greater than 0.8.
- the active bodies are preferably aligned parallel to one another. Further If a standing arrangement of the active body in the composite armor element is preferred, whereby a horizontal or an oblique arrangement is applicable.
- the active bodies of a layer can be arranged offset with respect to the active body of an adjacent layer. In the same way, the active bodies of a row can be staggered with respect to the active bodies of an adjacent row.
- the webs have predetermined dimensions, wherein the extent in relation to a rod-shaped or cylindrical active body radial direction is referred to as web length.
- the extent of the web in an axial direction is referred to as web height.
- the extent which is tangential to the lateral surface of a cylindrical active body is referred to as web width.
- the webs may be in relation to the main dimensions of the active body of short length and / or of small width, ie short and / or narrow.
- the web height can be in the range of the height of the active body.
- the number of connected active bodies can vary as desired and is preferably in the range from 5 to 20.
- the bars should have sufficient stability to enable safe handling in production.
- the webs in such a way to accomplish that the chain can be broken by hand or by machine in the manufacture of a composite armor to obtain the proper length.
- the ratio of the minimum web width to the maximum main dimension of the active body cross-section is less than 0.4.
- the web can have a score line, so that when the active-body chains are laid in the composite armor element shorter chains of active-body chains can be broken off, if this is necessary, for example, at the edge of the composite armor element ("Toblerone principle").
- Toblerone principle the production can be simplified.
- the geometry of the webs may be straight or have a fillet, further, a notch may be provided on one or more sides.
- the notch width can extend over the entire web length and the notch angle can be in the range between 40 ° and 100 °.
- the ratio of the web width at the notch base and the web length in the range of 0.3 to 2.5 can be.
- the webs may consist of plastics, in particular elastomers, or soft metals. They are firmly connected to the active bodies and can be formed with adhesive compounds or in whole or in part as constituents of active substances.
- the active-body chains are produced in one piece, so that rigid, "urgeformte" active-body chains arise. Thus, no individual active bodies are produced any more, but entire active-body chains are manufactured in one operation, in which the webs consist of the same material as the active body.
- the shock absorption is realized by the described formation of the land areas.
- the affected active body is completely destroyed and the top layer or the wall of the vehicle structure absorbs the residual impulse so that no penetration takes place in the interior to be protected. Due to the high local energy input, this process produces pronounced shockwaves, which are transmitted to the direct impact of the neighboring active body and also destroy it, even though it was not hit directly. This would be transferred to other adjacent active bodies and a large damaged area would be created that would no longer be safe in a subsequent shot.
- the webs according to the invention dampen the transmission of the shock wave by using the described materials or by the application of the described design of the thin webs or the provision of special notches. The destructive radii of the hit are thus minimized and the result is a good "multi-hit ability", ie even with several successive hits at a small distance, the protective function is maintained.
- the chain-shaped active body elements can be laid in straight rows within a layer in the composite armor plate. However, they can also be zigzag-shaped or curved. It is also possible to use multi-row active body matrices, which can be produced in one piece in particular and which can be arbitrarily broken during the production of the composite armor element.
- the arrangement of the active body chains is included after the compilation in the matrix material, in particular plastics such as polyurethane, epoxy resin, polyester or rubber, and can on the front side be completed by a cover layer.
- the other side may consist of layers made of materials with shock absorbing properties, which should also have a high tensile strength.
- the composite armor element may be self-supporting mounted in a frame construction or applied to a structural casing made of armor steel or light metal, wherein an air intermediate layer or shock absorbing intermediate layers may be provided.
- the invention is not limited to using only identical geometries and materials within a composite armor element. Rather, combinations of the described materials and geometries are encompassed by the invention.
- a particularly simple production can be achieved if, during manufacture, the chain-shaped active-body elements are inserted into a cassette of steel, light metal, plastic or fiber composite material, in particular made to measure, and then cast or vulcanized with a matrix material.
- the cassette becomes part of the protection module and can represent its outer layer or boundary.
- the active-body chains can also be inserted in a particularly dimensionally accurate manufacturing mold or in a production mold frame and then encapsulated or vulcanized with the matrix material.
