Abstract

Armour plate for a bulletproof car has a layer (2) of steel which absorbs the energy of bullets and prevents them penetrating the plate. This layer is made from hot-rolled, abrasion-resistant austenitic manganese steel which has no decarbonised layers at the edges and is hardened by cold working.

Description

Die Erfindung betrifft eine Panzerung, insbesondere für Sicherheitskraftfahrzeuge, mit welcher die Energie auftreffender Geschosse absorbiert und deren Durchdringung verhindert wird.The invention relates to an armor, in particular for Security vehicles, with which the energy impacted projectiles absorbed and their penetration is prevented.

Es sind zahlreiche Lösungen zur Auskleidung von Fahrzeugen mit beschußsicheren Matten oder der Karosserie nachgebildeten Formteilen aus faserverstärkten Kunststoffen bekannt, die als Panzerungselemente für Sicherheitskraftfahrzeuge Anwendung finden. Um auch hohen Beschußklassen standzuhalten muß die Dicke dieser Elemente jedoch so erhöht werden, daß der Einstieg und der Innenraum des Fahrzeuges unkomfortabel verringert werden. In DE G 92 15 781.5 U1 wird eine Panzerung für Fahrzeuge beschrieben, bei welcher die dem Innenraum des Fahrzeuges zugekehrte Oberfläche mit Panzerplatten aus Panzerstahl ausgekleidet wird. Die Stoßstellen werden mit Gewebematten großflächig übergreifend überdeckt. Die Kontur der Karosserieteile der Fahrzeuge kann mit diesen sehr harten Panzerplatten nicht nachgebildet werden, da diese eine ungenügende Umformbarkeit aufweisen. There are numerous solutions for lining vehicles with bulletproof mats or the body simulated moldings made of fiber-reinforced plastics known as armor elements for security vehicles Find application. To be too high Shelling classes must withstand the thickness of these elements However, be increased so that the entry and the interior of the vehicle are uncomfortably reduced. In DE G 92 15 781.5 U1 describes an armor for vehicles, in which the interior of the vehicle facing Surface lined with armor plates of armored steel becomes. The joints are large with tissue mats covered over. The contour of the body parts of the Vehicles can not handle these very hard armor plates be reproduced, since these are insufficient Have formability.

Es sind weiterhin warmgewalzte Baustähle aus austenitischen Manganhartstahl bekannt z.B. aus Dokument US-A-4 645 720, gemäß dem Oberbegriff des Anspruchs 1. Der Stahl wird vorwiegend als Schmiede-, Walz- oder Gußteil in der Hartzerkleinerung und im Berg- und Straßenbau für Reißzähne, Mäntel für Walzen- und Kegelbrecher, Schlagleisten für Prellbecher, usw. eingesetzt. Dieser Stahl neigt bei starker Umformung, d.h. bei starken Umformgraden, zu Rißbildung und ist für den Einsatz als Panzerung bisher nicht bekannt.It is still hot rolled austenitic structural steels Manganese hard steel known e.g. from document US-A-4 645 720, according to the preamble of claim 1. The steel is predominantly referred to as Forging, rolling or casting in hard shredding and in mining and road construction for fangs, coats for rolls and cone crushers, blow bars for bouncing cups, etc. used. This steel is prone to severe deformation, i. at strong degrees of deformation, cracking and is for the Use as armor not yet known.

Der Erfindung liegt die Aufgabe zugrunde, eine Panzerung für Sicherheitskraftfahrzeuge zu entwickeln, welche der Kontur der Fahrzeugkarosserie vollständig anpaßbar ist, ohne aufwendige Veränderungen der Karosserie in das Fahrzeug eingebaut werden kann und bei relativ geringem Gewicht eine gute Beschußsicherheit gewährleistet.The invention is based on the object, an armor for safety vehicles to develop which of Contour of the vehicle body is completely adaptable, without costly changes of the body in the Vehicle can be installed and at relatively low Weight ensures good fire safety.

Diese Aufgabe wird mit den Merkmalen des 1. Patentanspruchs gelöst. This object is achieved with the features of the first claim solved.

Das Verhältnis von Kohlenstoff- und Mangangehalt des Stahles liegt in etwa bei 1:10. Diese Eigenschaften werden beispielsweise von dem Stahl X120Mn12 (Nr. 1.340) erfüllt, bei welchem die bei der Warmumformung entstandene randentkohlte Schicht mechanisch, vorzugsweise durch Schleifen unter Kühlung (Temperatur maximal 250°C) entfernt wurde.The ratio of carbon and manganese content of the Steel is about 1:10. These properties will be for example, of the steel X120Mn12 (number 1.340), in which the resulting from the hot forming edge-decarburized layer mechanically, preferably by Grind with cooling (maximum temperature 250 ° C) away has been.

Vorteilhaft auf das ballistische Verhalten der Panzerung kann sich dabei auch die Verfestigung der Oberflächenstruktur des Grundgefüges beim Schleifen oder einer der mechanischen Bearbeitung nachgeordneten Bearbeitungsstufe (z.B. Sandstrahlen, der Beschuß mit Stahlkugen -Kugelstrahlen-, Diamantglätten, Kalibrieren oder Walzen mit geringer Zustellung) auswirken.Favorable to the ballistic behavior of the armor can also be the solidification of the Surface structure of the basic structure when sanding or one of the mechanical processing downstream Processing stage (e.g., sandblasting, bombardment with Stahlkugen shot blasting, diamond flattening, calibrating or rolls with low delivery).

Das Element kann entweder die Karosserie bilden oder diese verstärken und ein- bzw. mehrlagig ausgebildet sein, wobei die einzelnen Lagen zumindest bereichsweise miteinander verbunden (z.B.verschweißt) und gemeinsam umgeformt sind.The element can either form the bodywork or these strengthen and be formed one or more layers, wherein the individual layers at least partially with each other bonded (e.g., welded) and formed together.

Es ist auch möglich, das Element mit beschußhemmendem Material, beispielsweise Verbundfasermatten, zu hinterfüttern (backing) und/oder zumindest bereichsweise mit der Karosserie oder Karosserieteilen zu verschweißen und gemeinsam mit diesen umzuformen (taylored blanks). Die Dicke des Elements beginnt vorzugsweise ab 0,5 mm. Bei der mechanischen Bearbeitung wird beidseitig eine Schicht in der Größenordnung bis 0,25 mm abgetragen, so daß das randentkohlte Gefüge bis auf das Grundgefüge entfernt wird. Bei dem Verfahren zur Herstellung der Panzerung, insbesondere für Sicherheitskraftfahrzeuge, erfolgt zuerst das Warmwalzen des Elements aus verschleißfesten austenitischen Manganstahl, wobei entweder während des Warmwalzens die Entstehung einer randentkohlten Schicht durch Einsatz von Schutzgas vermieden wird, oder nach dem Warmwalzen das Abtragen der randentkohlten Schicht bis auf das Grundgefüge erfolgt.It is also possible to fire the element with bulletproof Material, such as composite fiber mats, too backing and / or at least regionally To weld with the body or body parts and to work with them (taylored blanks). The Thickness of the element preferably starts from 0.5 mm. In the Machining is done on both sides of a layer in of the order of magnitude up to 0.25 mm, so that the edge-decarburized structure is removed down to the basic structure. In the process of making the armor, especially for security vehicles, takes place first hot rolling of the element made of wear-resistant austenitic Manganese steel, either during hot rolling the emergence of a randentkohlten layer by use is avoided by inert gas, or after hot rolling the Removal of the edge-decarburized layer down to the basic structure he follows.

Bei Beschußversuchen wurde überraschender Weise festgestellt, daß sich die ballistischen Eigenschaften des Elements aus einem warmgewalzten verschleißfesten austenitischen Manganstahl nach dem Abschleifen wesentlich verbessert haben. Bereits mit einer Blechdicke von 2,5 mm wurde der Beschußklasse B4 standgehalten.When bombardment attempts became surprising found that the ballistic properties of the Elements of a hot-rolled wear-resistant austenitic manganese steel after grinding essential have improved. Already with a sheet thickness of 2.5 mm was withstood the B4 fire class.

Dabei wurde ursprünglich die mechanische Bearbeitung vorgenommen, um eine gleichmäßige Blechdicke für einen vorgesehenen Umformprozeß zu erzielen.This was originally the mechanical processing made to a uniform sheet thickness for a to achieve the intended forming process.

Als weiterer nicht vorhersehbarer positiver Effekt ist die bessere Kaltumformbarkeit und damit eine gute dreidimensionale Formbarkeit nach dem Entfernen der Randentkohlten Schicht zu verzeichnen. Es sind wesentlich höhere Umformgrade möglich, wobei eine Rißbildung in der Oberfläche, insbesondere bei kleinen Biegeradien, vermieden wird. Dadurch ist die Panzerung nahezu vollständig in der Art eines dreidimensionalen Formteiles an die Kontur der Fahrzeugkarosserie anpaßbar, da auch geringe Radien formbar sind. Die nicht vorhersehbaren hervorragenden ballistischen Eigenschaften ermöglichen die Herstellung einer Panzerung mit nur geringer Blechdicke, wodurch sich aufwendige Veränderungen der Karosserie und der Innenausstattung zum Einbau der Panzerung in das Fahrzeug auf ein Minimum reduzieren oder auch vollständig vermeiden lassen.Another unpredictable positive effect is the better cold workability and thus a good three-dimensional formability after removing the Edge decarburized layer record. It's essential Higher degrees of deformation possible, with a crack in the Surface, especially at small bending radii, avoided becomes. As a result, the armor is almost completely in the Type of a three-dimensional molded part to the contour of the Vehicle body adaptable because even small radii malleable are. The unpredictable outstanding ballistic Properties allow the production of armor with only small sheet thickness, which is costly Changes to the bodywork and interior decoration Installation of armor in the vehicle to a minimum reduce or even avoid completely.

Die Entfernung oder das Verhindern der Entstehung der randentkohlten Schicht wirkt sich somit positiv auf das ballistische Verhalten als auch auf die Kaltumformbarkeit aus. Beim Auftreffen eines Geschosses (Projektils) verformt sich die Panzerung ohne Rißbildung an dieser Position und verfestigt sich dabei zunehmend durch die dabei auftretende starke Aushärtung, so daß die Energie des Geschosses (Projektils) vollständig absorbiert wird.The removal or prevention of the emergence of Edge decarburized layer thus has a positive effect on the ballistic behavior as well as on cold workability out. Deformed when hitting a bullet (projectile) the armor without cracking at this position and increasingly solidified by the occurring strong curing, so that the energy of the projectile (Projectile) is completely absorbed.

Max. 1.30 0.50 13.5 0.10 0,040 o, 5 The hardness is 210 to 240 HBW (Brinell hardness).

Der Anteil der karbidbildenden Elemente (z.B. Crom -Cr-) soll dabei in der Summe unter 5% liegen und es sollen keine zeilenförmigen Ausscheidungen vorhanden sein. The proportion of carbide-forming elements (e.g., Crom -Cr-) should be in the sum below 5% and there should be no be present line-shaped precipitates.

Diese Panzerung hält nicht nur flächenhafte Stoßbelastungen aufgrund eines Fahrzeug-Crashs, sondern auch punktförmige Stoßbelastungen aufgrund von Beschuß der Beschußklassen FB3 und FB4 nach DIN EN 1522 zuverlässig ab, und zwar sowohl in ebenen als auch in gekrümmten Türbereichen.

Nicht dargestellt sind mehrere Lagen dieser Stähle, die bereichsweise miteinander verschweißt und gemeinsam umgeformt sind. Ihre Gesamtdicke kann wiederum beispielsweise bei etwa 2,5 bis 3,5 mm liegen. Selbstverständlich sind auch größere Blechdicken von Eizelblechen oder Mehrlagenblechen möglich.This armor does not only hold surface shock loads due to a vehicle crash, but also punctate Impact loads due to bombardment of the fire class FB3 and FB4 to DIN EN 1522 dependably, both in levels as well as in curved door areas. This kind of Armor can be realized very easily, from which also a high reliability of the bullet defense results. Not shown are several layers of these steels, the partially welded together and together are transformed. Your total thickness can turn for example, be about 2.5 to 3.5 mm. Of course, larger sheet thicknesses of Eizelblechen or multilayer sheets possible.

In Fig. 2 ist eine weitere Variante dargestellt, bei der das Karosserieblech 4 von etwa 1 mm Dicke durch eine innenliegende Panzerung 2 verstärkt ist. Obwohl ausschnittsweise vollflächig dargestellt, kann diese Verstärkung selbstverständlich auf besonders gefährdete Bereiche beschränkt bleiben, die auch stark geformt sein können.In Fig. 2, another variant is shown in the the body panel 4 of about 1 mm thickness by a internal armor 2 is reinforced. Even though shown in full detail, this can Reinforcement of course on particularly vulnerable Restrict areas that are also heavily shaped can.
