Description

Die vorliegende Erfindung beschreibt ein Verfahren zur Herstellung einer Zusatzpanzerung auf Keramikbasis.The present invention describes a method for producing a ceramic-based auxiliary armor.

Moderne Zusatzpanzerungen für gepanzerte Fahrzeuge müssen höchste ballistische Anforderungen erfüllen. Der zusätzlich aufgebrachte Schutzmantel der Fahrzeuge wird in einzelne Zusatzpanzerungselemente unterteilt, die jedes für sich einzeln an der Fahrzeugstruktur montiert sind. Die einzelnen Zusatzpanzerungselemente werden so groß als möglich gestaltet, da jeder Spalt und der Randbereich jedes Elementes eine Schwächung der Panzerung darstellt. Üblicherweise werden die Elemente genau an die Fahrzeugstruktur angepasst und gerade so groß gewählt, dass sie noch manuell manipuliert werden können.Modern auxiliary armor for armored vehicles must meet the highest ballistic requirements. The additionally applied protective jacket of the vehicles is subdivided into individual additional armor elements, which are individually mounted to the vehicle structure individually. The individual additional armor elements are made as large as possible, since each gap and the edge region of each element represents a weakening of the armor. Usually, the elements are precisely adapted to the vehicle structure and just chosen so large that they can still be manipulated manually.

Aufgrund der großen Härte und der geringen Porosität wird sehr oft ein keramisches Material, zum Beispiel Borcarbid, Siliziumcarbid, Aluminiumoxid oder Ähnliches, als ballistisches Schutzmaterial in Zusatzpanzerungen verwendet. Diese Keramiken haben zwar eine sehr große Härte, sind aber auch sehr spröde, sodass nach Auftreffen des ersten Treffers das Keramikelement meist in zahlreiche Teile zerspringt und kaum mehr einen zweiten Treffer halten kann. Um mehrere Treffer halten zu können, wird das Zusatzpanzerungselement in zahlreiche kleine Keramikelemente zerlegt, wobei die einzelnen Keramikelemente kleiner sein müssen als der geringste angenommene Schussabstand, bei dem die Zusatzpanzerung noch ihre Wirkung haben soll. Diese Teile werden entweder in eine Matrix aus einem anderen Schutzmaterial eingebettet, oder die Keramikelemente werden so geformt, dass sie aneinandergelegt eine Fläche vollständig ausfüllen können. In einer einfacher Ausführung kann dies durch regelmäßige Vielecke, zum Beispiel Dreiecke oder Vierecke erfolgen, aber auch durch kompliziertere ineinander greifende Formen wie zum Beispiel in der DE 3716055 beschrieben.Due to the high hardness and low porosity, a ceramic material such as boron carbide, silicon carbide, alumina or the like is very often used as a ballistic protective material in auxiliary armor. Although these ceramics have a very high hardness, but are also very brittle, so that after striking the first hit, the ceramic element usually bursts into numerous parts and can hardly hold a second hit. In order to hold multiple hits, the additional armor element is broken down into numerous small ceramic elements, the individual ceramic elements must be smaller than the lowest assumed shot distance at which the additional armor should still have their effect. These parts are either embedded in a matrix of another protective material, or the ceramic elements are shaped so that, when placed against each other, they can completely fill a surface. In a simple embodiment, this can be done by regular polygons, for example, triangles or squares, but also by more complicated interlocking shapes such as in the DE 3716055 described.

Bei der Plazierung dieser einzelnen Keramikelemente muss große Sorgfalt angewandt werden. Sind die Keramikelemente mit einem zu großen Abstand auf der Trägerplatte positioniert, so besteht die Gefahr eines ballistischen Loches, weil durch den zu großen Spalt die Stützwirkung des danebenliegenden Keramikelementes und damit eine Schutzfunktion nicht mehr gegeben ist, und ein auftreffendes Projektil möglicherweise nicht mehr gehalten wird. Liegen hingegen die einzelnen Keramikelemente direkt nebeneinander, so kann beim Auftreffen eines Geschosses auf ein Keramikelement die Schockwelle ungedämpft auf die Nebenelemente übertragen werden, die dann aufgrund der hohen Sprödigkeit der keramischen Schutzmaterialien zu brechen drohen und damit ihre Schutzwirkung verlieren.When placing these individual ceramic elements, great care must be taken. If the ceramic elements positioned too far on the support plate, so there is a danger of a ballistic hole, because the supporting effect of the adjacent ceramic element and thus a Protective function is no longer given, and an impacting projectile may no longer be held. If, on the other hand, the individual ceramic elements lie directly next to one another, then the shock wave can be transmitted undamped to the secondary elements when a projectile strikes a ceramic element, which then threaten to break due to the high brittleness of the ceramic protective materials and thus lose their protective effect.

Die DE 1952759 beschreibt ein Verfahren für eine keramische Zusatzpanzerung, bei der die einzelnen keramischen Schutzelemente, die die Form von regelmäßigen Vielecken haben, zur Isolierung zum benachbarten Element in einen Elastomerwerkstoff eingedrückt werden. Dieses Verfahren erfordert einen sehr hohen Arbeitsaufwand, weil jedes einzelne Element genauestens positioniert werden muss.The DE 1952759 describes a method for a ceramic supplemental armor, in which the individual ceramic protective elements, which have the shape of regular polygons, are pressed into an elastomeric material for insulation to the adjacent element. This process requires a great deal of work because every single element has to be precisely positioned.

Die DE 3716055 beschreibt eine Zusatzpanzerung mit komplex geformten, ineinander geschachtelten Keramikelementen, wobei der Zwischenraum der Elemente ebenfalls mit einem Elastomer ausgefüllt ist. Eine derartiges Panzerelement ist nur mit größtem Aufwand herzustellen, da beim Brennvorgang der Keramik eine deutliche Schrumpfung der Elemente auftritt, und mit einer hohen Ausschussquote gerechnet werden muss, wenn genaue Spaltmaße eingehalten werden sollen. Werden andererseits größere Toleranzen und damit größere Spaltmaße zugelassen, was auch für das Eindringen des Polymers in die Spalten erforderlich ist, besteht die Gefahr von unerwünschten ballistischen Löchern.The DE 3716055 describes an additional armor with complex shaped, nested ceramic elements, wherein the gap of the elements is also filled with an elastomer. Such an armor element can be produced only with the greatest effort, since during the firing of the ceramic, a significant shrinkage of the elements occurs, and must be expected with a high reject rate, if accurate clearances are to be met. On the other hand, larger tolerances and thus larger gaps allowed, which is also required for the penetration of the polymer in the columns, there is a risk of unwanted ballistic holes.

Der gegenständlichen Erfindung liegt die Aufgabe zugrunde, ein kostengünstiges Herstellungsverfahren zu schaffen, das sowohl die Isolierung der Schockwellen zwischen den einzelnen Elementen ermöglicht, als auch den korrekten Abstand zwischen den einzelnen Keramikelementen sicherstellt. Die Erfindung löst diese Aufgabe dadurch dass die Keramikelemente zur Sicherstellung der Isolierung einer Schockwelle beim Auftreffen eines Geschosses vom Nachbarelement durch eine dünne, mittels Pulverbeschichtung aufgetragene elastische Lackschicht auf den Keramikelementen isoliert werden. Weitere Merkmale der Erfindung sind in den Unteransprüchen gekennzeichnet.The present invention has for its object to provide a cost-effective manufacturing process that allows both the isolation of the shock waves between the individual elements, as well as the correct distance between the individual ceramic elements ensures. The invention solves this problem in that the ceramic elements to ensure the isolation of a shock wave when hitting a projectile from the neighboring element by a thin, applied by powder coating elastic lacquer layer on the ceramic elements are isolated. Further features of the invention are characterized in the subclaims.

Die Fig. 1 bis 3 zeigen beispielhaft mögliche Ausführungsformen von Zusatzpanzerungsplatten mit unterschiedlichen Keramikelementen. Fig. 1 zeigt eine Zusatzpanzerplatte mit dreieckigen, Fig. 2 mit quadratischen und Fig. 3 mit sechseckigen Keramikelementen. Fig. 4 zeigt einen beispielhaften Querschnitt durch den Aufbau der Zusatzpanzerungsplatten.The Fig. 1 to 3 show examples of possible embodiments of additional armor plates with different ceramic elements. Fig. 1 shows an auxiliary armor plate with triangular, Fig. 2 with square and Fig. 3 with hexagonal ceramic elements. Fig. 4 shows an exemplary cross section through the structure of the additional armor plates.

Erfindungsgemäß werden die einzelnen Keramikelemente 1 mit einem Lack 2 beschichtet. In einer bevorzugten Ausführung erfolgt diese Lackbeschichtung mittels eines Pulverlackes. Bei einer Pulverbeschichtung wird meistens der zu beschichtende Körper elektrostatisch aufgeladen, der Pulverlack, der komplementär zum zu beschichtenden Körper aufgeladen ist, wird über den Körper gesprüht und haftet aufgrund der elektrischen Anziehung der unterschiedlich elektrisch geladenen Komponenten. Die Schichtstärke des Pulverlackes kann dabei sehr präzise gesteuert werden. Anschließend wird der Pulverlack thermisch fixiert.According to the invention, the individual ceramic elements 1 are coated with a lacquer 2. In a preferred embodiment, this lacquer coating is carried out by means of a powder coating. In a powder coating, the body to be coated is usually electrostatically charged, the powder coating, which is charged in a complementary manner to the body to be coated, is sprayed over the body and adheres due to the electrical attraction of the differently electrically charged components. The layer thickness of the powder coating can be controlled very precisely. Subsequently, the powder coating is thermally fixed.

Da Keramik nicht elektrisch leitend ist, muss diese vorher in geeigneter Weise vorbehandelt werden. Geeignete Verfahren sind z.B. in der EP 0963795 und in der DE 4417172 beschrieben.Since ceramic is not electrically conductive, it must first be pretreated in a suitable manner. Suitable methods are, for example, in EP 0963795 and in the DE 4417172 described.

Alternativ zur elektrostatischen Aufladung kann das mittels Pulverlack zu beschichtende Keramikelement auch thermisch auf eine Temperatur über den Schmelzpunkt des Pulverlackes aufgeheizt werden. Bei der Pulverbeschichtung bleiben die Lackpartikel dadurch an der Oberfläche kleben. Dieses Verfahren hat jedoch den Nachteil, dass die Schichtstärke nicht so präzise wie bei der elektrostatischen Aufladung gesteuert werden kann.As an alternative to electrostatic charging, the ceramic element to be coated by means of powder coating can also be heated thermally to a temperature above the melting point of the powder coating. In the case of powder coating, the paint particles thereby stick to the surface. However, this method has the disadvantage that the layer thickness can not be controlled as precisely as in the electrostatic charging.

Pulverlack gibt es in verschiedenen Qualitäten, die sich auch durch ihre elastischen Eigenschaften unterscheiden. Bei einer geeigneten Auswahl kann ein Pulverlack 2 verwendet werden, der ähnliche Eigenschaften wie ein Elastomer aufweist und bestens zur Isolierung der Schockwellen zwischen den einzelnen Keramikelementen 1 geeignet ist.Powder paint is available in different qualities, which also differ by their elastic properties. With a suitable choice, a powder coating 2 can be used, which has similar properties as an elastomer and is well suited for the isolation of the shock waves between the individual ceramic elements 1.

Die nun mit diesem Pulverlack 2 beschichteten Keramikelemente 1 können mit geringst möglichem Aufwand nebeneinander plaziert werden und, wie in Fig. 4 dargestellt, in herkömmlicher Weise weiter zu einer Zusatzpanzerungsplatte 3 verarbeitet werden, indem sie auf eine Tragplatte 4 aufgebracht und mit einer Schutzabdeckung 5 versehen werden. Eine genaue Positionierung ist nicht erforderlich, die einzelnen Keramikelemente 1 werden einfach aneinander geschoben, der genaue Abstand ist durch die Pulverbeschichtung 2 gewährleistet.The now coated with this powder coating 2 ceramic elements 1 can be placed next to each other with the least possible effort and, as in Fig. 4 shown, are processed in a conventional manner to an additional armor plate 3 by being applied to a support plate 4 and provided with a protective cover 5. Accurate positioning is not required, the individual ceramic elements 1 are simply pushed together, the exact distance is ensured by the powder coating 2.

Im Rahmen der Erfindung können auch zahlreiche anders als in den Fig. 1 bis 3 gezeigte geformte Keramikelemente 1 verwendet werden.In the context of the invention, numerous other than in the Fig. 1 to 3 shown molded ceramic elements 1 can be used.
