Definitions
- the invention relates to a ceramic armor plate. Furthermore, the invention relates to an armor system. The invention also relates to a method of manufacturing a ceramic armor plate.
- An armor system is known from, for example, EP 0 810 415 B1 (DE 697 07 560 T2).
- An armor system may comprise a plurality of ceramic tiles arranged in a tile layer. The purpose of the ceramic tiles is to destroy the core of a striking projectile due to the hardness of the ceramic.
- a ceramic armor plate and an armor system that can be produced in a simple manner are provided.
- a ceramic armor plate is formed in one piece and comprises a plurality of connected segments which are functionally separated by crack stoppers, wherein the crack stoppers serve to prevent the propagation of cracks from one segment to a neighboring segment.
- a one-piece armor plate incorporating integrally produced crack stoppers is provided. The manufacturing process is therefore considerable simplified since there is no need to manufacture a plurality of individual tiles which must then be joined together, but rather, a whole plate covering a larger surface area is manufactured in an integral manner. Since a joining process is not necessary, the problems associated therewith are also avoided. For example, deformation and a decrease in size can occur when manufacturing ceramic plates.
- the crack stoppers can be formed in a simple manner during the manufacturing process; for example, by means of cracks produced in a defined manner or by means of grooves which are formed before the ceramicization process. It is thereby possible to produce the functional segments such that they are defined for the desired field of application.
- the armor plate of the inventon may be formed in multiple layers for example, whereby the crack stoppers can be arranged in different ways in the differing layers. Therefore, there are a large number of ways for controlling and adjusting the course of a crack in the event of bombardment and, thus, controlling the ballistic characteristics of the armor plate.
- the crack stoppers it is especially advantageous for the crack stoppers to be integrated into the armor plate. Consequently, the armor plate can easily be manufactured and an armor system comprising at least one armor plate in accordance with the invention can also be manufactured in a simple manner.
- the crack stoppers are formed in the solid material of the armor plate so that separate tiles that have to be joined at a later time do not need to be provided.
- the process of manufacturing the armor plate is thereby considerably simplified, whereby a large surface area can be manufactured in a simple manner.
- the crack stoppers are produced when manufacturing the armor plate.
- the crack stoppers are formed by recesses and/or from recesses.
- the recesses can be produced in a particularly simple manner prior to the process of ceramicizing an armor plate preform. They can be arranged in a defined manner. For example, a grid of recesses can be produced. Furthermore, the recesses can be produced with defined depths.
- the recesses are not necessarily still present. For example, they are filled with a parting agent before infiltrating them with carbide-forming materials (such as silicon for the siliconizing process).
- the recesses are produced in the thickness direction of the armor plate.
- the armor plate is thus divided into functional segments, whereby the segments are contiguous.
- the recesses prevent propagation of a crack beyond a segment if a segment experiences an impact such as the impact of a projectile for example.
- the recesses can be produced at an angle of between 15° and 45° with respect to a thickness direction of the armor plate. This can be advantageous for certain fields of application.
- crack stoppers are formed by grooves and/or from grooves.
- Such grooves can be produced in a simple manner, for example, by a milling process or laser working or a water-jet cutting process. It is preferable for the depth of the grooves to lie in a range of between 0.05 and 0.9, and preferably between 0.1 and 0.6 of the thickness of the armor plate. Consequently, a crack stopping effect can be obtained on the one hand and a one-piece armor plate can be formed on the other.
- the crack stoppers are formed by perforations and/or from perforations for example.
- the crack stoppers can be formed by cracks.
- Such cracks can be produced in a defined manner, in that, for example, cover plates (covering layers) are placed on a solid material perform, these plates having a different coefficient of thermal expansion than that of the solid material preform.
- An integral composite material having cracks formed therein is produced in the subsequent ceramicization process.
- the cracks serving as crack stoppers run between an upper surface and a lower surface on the armor plate.
- the armor plate can be divided into functional segments, whereby the propagation of cracks beyond segments is stoppable.
- the cracks run at least approximately in the thickness direction of the armor plate.
- the armor plate can be divided into segments which correspond to a composite tile structure having joints between the tiles although the armor plate is formed in one piece.
- covering layers are provided between which the cracks extend.
- the armor plate is thereby covered by a crack-free covering layer at the upper surface and lower surface thereof. Due again to the covering layers, it is then possible to produce defined cracks during the process of manufacturing the armor plate.
- the covering layers are made of C/C—SiC for example.
- C/C preforms are fixed on the lower surface and the upper surface of a porous C preform, and this is then followed by a siliconizing process.
- Covering layers consisting of C—C—SiC can thereby be formed. Due to the different material properties, a crack structure can be produced during the siliconizing process or during the process of cooling the body infiltrated with silicon, whereby the cracks run between the covering layers. Again, the functional segments can be produced thereby.
- the size of the segments can be established by using different layers having differing coefficients of the thermal expansion.
- the crack stoppers in principle, it is possible for the crack stoppers to be in the form of defects such as cracks for example.
- the distance between the crack stoppers lies in a range of between 5 mm and 100 mm, and preferably in a range of between 30 mm and 50 mm.
- the layers are thereby formed together in one piece.
- a plurality of layers are joined together in one piece (in situ) in the course of the ceramicization process (such as by in infiltration of liquid silicon, i.e., a siliconizing process for example).
- the armor plate is made of a silicon carbide ceramic. This material has a high hardness so that a projectile striking it is destroyed. It is also conceivable for the armor plate to be manufactured from other carbide forming metals such as titanium or chrome.
- the crack stoppers prefferent in certain embodiments for the crack stoppers to be introduced into the ceramic material of the armor plate and embedded therein. There is, thus, no connection between the crack stoppers and the surfaces of the plate.
- the armor plate can be manufactured, in particular, from a carbon-containing preform.
- a preform is workable in a simple manner. It is capable of being at least partially ceramicized.
- this preform is manufactured by means of graphite powders and bonding agents.
- the armor plate in accordance with the invention can be manufactured economically, particularly where the ceramic material of the armor plate is manufactured by means of a biomorphic material and, in particular, a cellulose containing material.
- Appropriate manufacturing processes are described in the not prior published German Application No. 103 29 822.3, dated Jun. 30, 2003, or in DE 199 47 731 A1. Express reference to these documents is made.
- the armor plate in accordance with the invention can be utilized advantageously in an armor system which comprises at least one armor plate in accordance with the invention.
- a corresponding armor system has, in particular, a multi-layer structure.
- An example is described in EP 0 810 415 B1, which is incorporated by reference herein. Instead of a plurality of tiles as is described therein, at least one armor plate in accordance with the invention can be used.
- the at least one armor plate is seated on a backing (a structural supporting layer) which is preferably made of a lightweight construction material such as aluminium or carbon KEVLAR® or aramid.
- a method for the manufacture of a ceramic armor plate which can be carried out in a simple manner.
- crack stoppers are produced in an armor plate preform and the armor plate is divided into contiguous functional segments by the crack stoppers.
- the crack stoppers (for the armor plate being manufactured) are formed, namely, in an armor plate preform into which they can be introduced without complication in the course of the manufacturing process for the ceramic armor plate. This results in an easy manner of fabrication, whereby defined functional segments are obtainable by means of a defined process of producing crack stoppers.
- the method in accordance with the invention has the advantages already described in connection with the ceramic armor plate in accordance with the invention. Further advantageous embodiments of the method in accordance with the invention were likewise explained hereinbefore in connection with the ceramic armor plate in accordance with the invention.
- the crack stoppers In principle, it is possible for the crack stoppers to be introduced after the ceramicization process. However, the crack stoppers are typically produced before the armor plate material is subjected to the ceramicization process. It is then possible for the crack stoppers to be formed in the material by means of a machining process for example. In the stage before the ceramicization process, the material is less hard by far than after the ceramicization process and is therefore more easily worked.
- the crack stoppers are formed by the production of recesses. These can be produced in a simple manner such as to have a defined arrangement and shape by means of a mechanical material-working process such as a machining process (e.g., milling, boring, grinding, etc.) and/or beam processing such as laser working or water-jet machining.
- a mechanical material-working process such as a machining process (e.g., milling, boring, grinding, etc.) and/or beam processing such as laser working or water-jet machining.
- the purpose of the parting agent is to ensure the crack stopping function for the finished armor plate (which is subjected to a ceramicization process).
- the parting agent serves to prevent wetting with a carbide-forming material during the ceramicization process.
- the filling process can be effected using a carbon-rich paste. Carbon webs can thereby be produced in a ceramic armor plate.
- the filling process could also be effected using silicon.
- the crack stoppers can be produced in the form of defined cracks.
- the cracks are produced by the connection to cover plates. These cover plates are placed on a preform prior to the ceramicization process. A one-piece connection of the cover plates is effected by means of the ceramicization process, for example by means of a siliconizing process, whereby cracks are producible.
- the cover plates are made of C/C, i.e., made of carbon fiber reinforced carbon.
- the characteristics of the ceramic armor plate can thus be controlled or adjusted in a defined manner.
