Description

Die Erfindung betrifft eine Panzervorrichtung, wie sie im Oberbegriff von Anspruch 1 gekennzeichnet ist und ein Verfahren zu deren Herstellung.The invention relates to a tank device as characterized in the preamble of claim 1 and a method for their production.

Eine Panzervorrichtung der eingangs genannten Art ist bekannt geworden (US-A-4 179 979), wobei nichtmetallische Kugeln in Schichten mit dazwischenliegendem Schichtmaterial ausgerichtet angeordnet sind, wobei die Zwischenräume mit einem Polyurethan-Schaum ausgefüllt sind. Diese Anordnung ermöglicht im wesentlichen nur die Herstellung plattenförmiger Schutzelemente, so dass Anordnungen in beliebigen Hohlräumen zwischen Panzerplatten nicht möglich ist. Ausserdem ist der Herstellungsaufwand wegen der ausgerichteten Anordnung der Kugeln sehr hoch.A tank device of the type mentioned at the outset has become known (US Pat. No. 4,179,979), non-metallic balls being arranged in layers with layer material lying therebetween, the interstices being filled with a polyurethane foam. This arrangement essentially only enables the production of plate-shaped protective elements, so that arrangements in any cavities between armored plates are not possible. In addition, the manufacturing effort is very high because of the aligned arrangement of the balls.

Die DE-A-2 759 193 zeigt ebenfalls eine plattenförmige Schutzpanzerung, bei welcher Schichten von dickwandigen Hohlkugeln aus z. B. auch Oxyd-Keramik in geordneter Lage in Nylon oder Kunstharz eingebettet sind. Diese Schutzpanzerung ist vorwiegend zum Schutz gegen Gewehrgeschosse bei Personen und leichten Fahrzeugen gedacht.DE-A-2 759 193 also shows a plate-shaped protective armor, in which layers of thick-walled hollow spheres made of e.g. B. also oxide ceramics are neatly embedded in nylon or synthetic resin. This protective armor is primarily intended to protect against rifle projectiles on people and light vehicles.

Im weiteren sind Schutzpanzerungen für Wurfgeschosse bekannt geworden (US-A-3 573 150 und EP-A-0 041 271), bei welchen reihenförmig, vorzugsweise runde Stäbe aus Glas oder Keramik in einem Elastomer oder einem Polymer-Kunststoff eingebettet sind, wobei nur quaderförmige Schutz-Moduli damit erstellbar sind.In addition, protective armor for projectiles has become known (US-A-3 573 150 and EP-A-0 041 271), in which rows, preferably round rods made of glass or ceramic are embedded in an elastomer or a polymer plastic, only cuboid protection moduli can thus be created.

Alle Panzervorrichtungen der vorgängig genannten Art haben keine oder nur eine ungenügende Schutzwirkung gegen Hohlladungen. Aufgabe der vorliegenden Erfindung ist die Schaffung einer Panzervorrichtung der eingangs genannten Art, welche durch einfache Mittel eine höhere Schutzwirkung gegen Hohlladungen gewährleistet, wobei speziell die Sicherheit gegen Mehrfachbeschuss verbessert werden soll. Ausserdem soll die Panzervorrichtung ein geringes Gewicht aufweisen und in unterschiedlichsten Formgestaltungen verwendbar bzw. herstellbar sein.All armor devices of the type mentioned above have no or only insufficient protection against shaped charges. The object of the present invention is to provide a tank device of the type mentioned at the outset which, by simple means, ensures a higher protective action against shaped charges, the security against multiple bombardment in particular being improved. In addition, the armor device should have a low weight and be usable or producible in a wide variety of shapes.

Erfindungsgemäss wird dies durch die im kennzeichnenden Teil von Anspruch 1 angegebenen Merkmale gelöst.According to the invention this is solved by the features specified in the characterizing part of claim 1.

Weitere vorteilhafte Ausgestaltungen sind in den abhängigen Ansprüchen gekennzeichnet.Further advantageous configurations are characterized in the dependent claims.

Durch die Anordnung einer Vielzahl von hohlkugelförmigen Füllkörpern variabler oder gleicher Grösse, unregelmässiger oder regelmässiger Orientierung zueinander, welche in einem Polyurethan-Zweikomponenten-Kunststoff eingebettet sind, entsteht eine Panzervorrichtung mit im Querschnitt rasch wechselnder Materialdichte und Orientierung. Bei derartigen sprungartigen Aenderungen der Dichte und Struktur nimmt die Wirkung des bei Hohlladungen entstehenden Hitzestrahles rasch ab, wodurch die Schutzwirkung erhöht wird. Durch die Einbettung der Füllkörper in den Kunststoff wird die Sicherheit gegen Mehrfachbeschuss erhöht.The arrangement of a large number of hollow spherical fillers of variable or equal size, irregular or regular orientation with respect to one another, which are embedded in a two-component polyurethane plastic, results in a armored device with a rapidly changing cross section of material density and orientation. In the case of such sudden changes in density and structure, the effect of the heat radiation generated in the case of shaped charges rapidly decreases, as a result of which the protective effect is increased. By embedding the filler in the plastic, security against multiple bombardment is increased.

Vorzugsweise bestehen die hohlkugelförmigen Füllkörper aus Korund, welches eine grosse Härte bei geringem spezifischen Gewicht aufweist. Die Kombination dieser Hohlkugeln mit dem Polyurethan-Zweikomponenten-Kunststoff ergibt ein geringes spezifisches Gewicht der Panzerung. Ausserdem ermöglicht diese Kombination das Ausfüllen von Hohlräumen unterschiedlichster Form, so dass auch unzugängliche Stellen mit einer Schutzpanzerung versehen werden können. Andererseits können damit feste ausgehärtete Blöcke als Moduli hergestellt werden, welche z. B. auf Panzerplatten angeordnet einen kombinierten Schutz bilden.The hollow spherical fillers preferably consist of corundum, which has great hardness with a low specific weight. The combination of these hollow spheres with the polyurethane two-component plastic results in a low specific weight of the armor. In addition, this combination enables the filling of cavities of various shapes, so that even inaccessible areas can be provided with protective armor. On the other hand, solid cured blocks can be produced as moduli, which, for. B. arranged on armor plates form a combined protection.

Die Erfindung ist anhand von mehreren Ausführungsbeispielen in den beiliegenden Zeichnungen dargestellt und nachfolgend beschrieben.The invention is illustrated using several exemplary embodiments in the accompanying drawings and described below.

  • FIG. 1 shows a first exemplary embodiment of a tank device in partial cross section,
  • FIG. 2 shows a second exemplary embodiment from FIG. 1,

Entsprechend Fig. 1 sind in einer aus Panzerstahl bestehenden Panzerplatte 1 bzw. einem Panzerplattenelement - auch Modul genannt - Hohlräume 2 gleichmässig oder ungleichmässig verteilt angeordnet, welche mindestens eine Einfüllöffnung aufweisen, vorzugsweise aber von der äusseren Oberfläche aus zugänglich sind.According to FIG. 1, cavities 2 are arranged in an armor plate 1 or an armor plate element - also called a module - evenly or unevenly distributed, which have at least one filling opening, but are preferably accessible from the outer surface.

In den Hohlräumen 2 sind hohlkörperförmige Füllkörper 3 angeordnet. Die Hohlräume 2 können an der Aussenseite als auch an der Innenseite einer Panzerplatte bzw. eines Plattenelementes angeordnet und mit einer Platte abgedeckt werden.Hollow-shaped fillers 3 are arranged in the cavities 2. The cavities 2 can be arranged on the outside as well as on the inside of an armor plate or a plate element and covered with a plate.

Die Füllkörper 3 sind Hohlkugeln 13 oder hohlkugelförmig ausgebildet. Die Füllung jedes Hohlraumes 2 kann Füllkörper 3 gleicher oder unterschiedlicher Grösse, gleichen oder unterschiedlichen nichtmetallischen Materials aufweisen. Vorzugsweise bestehen die Hohlkugeln aus Keramik - insbesondere Korund -, sie können aber auch aus Glas oder einem anderen nichtmetallischen Material hergestellt sein. Die Hohlkugeln 13 bzw. Füllkörper 3 können in einer regelmässig geschichteten Orientierung bzw. Lage in den Hohlräumen angeordnet sein (siehe Fig. 1 rechts) oder sie sind in einer, durch eine Schüttung mit möglichst grosser Schüttdichte sich ergebenden unregelmässigen Orientierung zueinander im Hohlraum angeordnet (siehe Fig. 1 links, Fig. 2). Die verbleibenden Zwischenräume werden mit einem aushärtbaren Zweikomponenten-Kunststoff 8 wie z. B. einem Polyurethan-Schaumstoff ausgefüllt, bzw. ausgeschäumt. Die Füllkörper können auch vor oder nach dem Einfüllen mit einem organischen oder anorganischen Binder wie z. B. Monoalumiphosphatbinder bzw. einem aushärtbaren Kunststoff verbunden, verklebt oder übergossen werden, welcher nach dessen Erstarrung einen Zusammenhalt der einzelnen Füllkörper bewirkt. Bei Füllkörpern aus Keramik können die einzelnen Körper auch durch Sintern miteinander verbunden werden. Der Aussendurchmesser der verwendenten Hohlkugeln liegt vorteilhafterweise in einem Bereich zwischen 3 und 15 mm. In Fig. 2 wird der Hohlraum 2 durch eine äussere Panzerplatte 10 und eine innere Panzerplatte 11, z. B. eines Panzerfahrzeuges gebildet, wobei durch eine Oeffnung 12 die vorzugsweise hohlkugelförmigen Füllkörper 3 zusammen mit dem Kunststoff oder nacheinander eingefüllt werden.The filler 3 are hollow spheres 13 or hollow spherical. The filling of each cavity 2 can have fillers 3 of the same or different size, same or different non-metallic material. The hollow spheres preferably consist of ceramic - in particular corundum - but they can also be made of glass or another non-metallic material. The hollow spheres 13 or fillers 3 can be arranged in the cavities in a regularly layered orientation or position (see FIG. 1 on the right) or they are arranged in an irregular orientation with respect to one another in the cavity due to a bulk density with the greatest possible bulk density ( see Fig. 1 left, Fig. 2). The remaining spaces are covered with a curable two-component plastic 8 such. B. filled or foamed a polyurethane foam. The packing can also before or after filling with an organic or inorganic binder such. B. monoaluminum phosphate binder or a curable plastic can be bonded, glued or poured over, which after solidification causes the individual packing to hold together. In the case of ceramic fillers, the individual bodies can also be connected to one another by sintering. The outside diameter of the hollow balls used is advantageously in a range between 3 and 15 mm. In Fig. 2, the cavity 2 is an outer armor plate 10 and an inner armor plate 11, for. B. an armored vehicle, the preferably hollow spherical filler 3 are filled in together with the plastic or in succession through an opening 12.

Das Verhältnis des Volumens VH des Hohlraumes zum Volumen V des Füllkörpers sollte grösser als 100, vorzugsweise grösser als 250 sein. Füllkörper mit einem mittleren Durchmesser DM von mindestens 3 mm und maximal 15 mm ergeben die gewünschten Volumenverhältnisse bei einer vorteilhaften Hohlraumgrösse. Das Verhältnis des Volumens eines Hohlraumes VH zu dem reinen Materialvolumen VF aller eingelegter Füllkörper sollte grösser als 2 sein. Bei derartigen Verhältnissen wird bei einem möglichst geringen Gewicht der Panzervorrichtung eine gute Schutzwirkung erreicht.The ratio of the volume V H of the cavity to the volume V of the packing should be greater than 100, preferably greater than 250. Packing bodies with an average diameter D M of at least 3 mm and a maximum of 15 mm result in the desired volume ratios with an advantageous cavity size. The ratio of the volume of a cavity V H to the pure material volume V F of all inserted packing should be greater than 2. In such conditions, a good protective effect is achieved with the lowest possible weight of the armor device.

Nach dem Einfüllen der Füllkörper 3 in den jeweiligen Hohlraum 2 werden dann, wie bereits beschrieben, die Zwischenräume mit einem Zweikomponenten-Kunststoff, vorzugsweise mit einem Schaumstoff, z. B. aus Polyurethan ausgefüllt bzw. ausgeschäumt oder können auch vor oder nach .dem Einfüllen mit einem anorganischen oder organischen Binder verklebt oder übergossen werden, welcher nach dessen Erstarrung einen Zusammenhalt der einzelnen Füllkörper bewirkt.After filling the filler 3 in the respective cavity 2, the gaps are then, as already described, with a two-component plastic, preferably with a foam, for. B. filled or foamed from polyurethane or can also be glued or poured over before or after filling with an inorganic or organic binder, which after solidification causes the individual packing to hold together.

Das Herstellen der Hohlraum-Füllung mit Füllkörpern und einem Zweikomponenten-Kunststoff kann auf unterschiedliche Weise erfolgen.The cavity filling with fillers and a two-component plastic can be produced in different ways.

Variante A Füllkörper, erste Komponente und Netzmittel mischen und kurz vor dem Einfüllen in den Hohlraum bzw. in eine Form zweite Komponente zumischen.Variant A Mix packing, first component and wetting agent and mix in second component shortly before filling into the cavity or into a mold.

Variante B Beide Komponenten und Füllkörper mischen und anschliessend einfüllen.Variant B Mix both components and packing and then fill in.

Variante C Füllkörper einfüllen, Polyurethan-Gemisch unter Ueberdruck oder Schwerkraft einfüllen. Diese Variante kann auch bei einer zueinander orientierten Lage der Füllkörper verwendet werden.Variant C Fill in the packing, fill in the polyurethane mixture under overpressure or gravity. This variant can also be used in the case of a position of the packing which is oriented to one another.

Sollen entsprechend Fig. 3 feste ausgehärtete Blöcke 20 aus Füllkörpern 3 und Kunststoff zum Einsetzen in die Hohlräume oder zum Aufsetzen auf Platten hergestellt werden, können diese mit einem Drahtgeflecht oder Streckmetall 21 armiert werden. Derartige Blöcke werden in einer Form hergestellt, wobei in der Form zuerst die Armierung 21 fixiert wird und anschliessend die Füllkörper 3 und der Kunststoff nach einem der Verfahren A, B oder C eingefüllt wird.If, according to FIG. 3, solid, hardened blocks 20 are to be produced from packing elements 3 and plastic for insertion into the cavities or for placement on plates, these can be reinforced with a wire mesh or expanded metal 21. Blocks of this type are produced in a mold, the reinforcement 21 being first fixed in the mold and then the filler 3 and the plastic being filled in according to one of the methods A, B or C.

Entsprechend Fig. 4 weist der Block 20 zwischen den Füllkörpern 3 - vorzugsweise Hohlkugeln 13 - mehrere Schichten plattenförmiger Elemente 22 auf, welche vorzugsweise aus Keramik oder Glas bestehen.4, the block 20 between the packing 3 - preferably hollow spheres 13 - has several layers of plate-shaped elements 22, which preferably consist of ceramic or glass.

Eine weitere Ausführungsvariante eines Blocks 21 zeigt Fig. 5, wobei die plattenförmigen Elemente 22 in mehreren Schichten auf der, der Bedrohungsrichtung 4 gegenüberliegenden Seite des Blockes angeordnet sind und ungefähr 1/3 der Höhe h des Blockes einnehmen. Vorteilhafterweise sind die plattenförmigen Elemente 22 mit einer Ummantelung 23 aus Kunststoff wie z. B. Polyurethan oder einem Elastomer versehen.A further embodiment variant of a block 21 is shown in FIG. 5, the plate-shaped elements 22 being arranged in several layers on the side of the block opposite the threat direction 4 and occupying approximately 1/3 of the height h of the block. Advantageously, the plate-shaped elements 22 with a sheath 23 made of plastic such. B. polyurethane or an elastomer.

Derartige Blöcke können auch als Moduli bei einer, eine kombinierte Schutzwirkung gegen verschiedenartige Geschosse aufweisenden Panzerüng verwendet werden, wobei diese Moduli insbesonders den Schutz gegen Hohlladungen bilden.Blocks of this type can also be used as moduli in the case of a armor arm having a combined protective action against different types of projectiles, these moduli in particular forming protection against shaped charges.

Die Hohlräume bzw. die ausgehärteten Blöcke können sowohl an der Aussenseite als auch an der Innenseite einer Panzerplatte bzw. eines Plattenelementes angeordnet und mit einer Platte abgedeckt werden.The cavities or the hardened blocks can be arranged both on the outside and on the inside of an armor plate or a plate element and covered with a plate.

Wesentlich für die Erhöhung der Sicherheit gegen Mehrfachbeschuss ist die Optimierung des verwendeten Zweikomponenten-Kunststoffes, vorzugsweise eines Polyurethans.It is essential to increase security against multiple bombardment by optimizing the two-component plastic used, preferably a polyurethane.

Die Optimierung erfolgt bezüglich Festigkeit, Zähigkeit, Härte, Verarbeitbarkeit und bzw. oder durch geeignete Armierung bzw. Vernetzung.The optimization takes place with regard to strength, toughness, hardness, processability and / or by means of suitable reinforcement or cross-linking.

Selbstverständlich können Art und Anordnung der Füllkörper, der verwendete Kunststoff und das Herstellungsverfahren bei den beschriebenen Ausführungsbeispielen unterschiedlich kombiniert werden, wodurch sich weitere, im Rahmen der Erfindung liegende Ausführungsvarianten ergeben.Of course, the type and arrangement of the packing, the plastic used and the manufacturing process can be combined differently in the described exemplary embodiments, which results in further design variants within the scope of the invention.

Insbesonders können mehrere Schichten mit jeweils unterschiedlich grossen Füllkörpern angeordnet werden.In particular, several layers, each with differently sized packing elements, can be arranged.

In Abwandlung von Fig. 4 können z. B. die Schichten mit den plattenförmigen Elementen 22 durch Füllkörper 3, 13 mit einem gegenüber den anderen Füllkörpern wesentlich grösseren Durchmesser angeordnet werden.
