Abstract
Description
"Beschußsichere Panzerung für Kraftfahrzeuge" Die Erfindung betrifft eine beschußsichere, aus mehreren Schichten bestehende Panzerung für Kraftfahrzeuge, insbesondere Geldtransportwagen, mit einer äußeren, vorzugsweise oberflächenverfestigten Stahiplatte und einer dahinter angeordneten Kunststoffschicht, welche gegebenenfalls nach innen von einer weiteren Stahlplatte abgedeckt ist bzw aus einer mehrfach hintereinander angeordneten Schichtung von Kunststoff- und Stahlplatten. "Bulletproof Armor for Motor Vehicles" The invention relates to bulletproof, multi-layer armor for motor vehicles, in particular money transport trolley, with an outer, preferably surface-solidified Steel plate and a plastic layer arranged behind it, which if necessary is covered on the inside by another steel plate or from one several times in a row arranged layering of plastic and steel plates.
Panzerungen aus Kombinationen von Metall mit Kunststoff sind in verschiedenen Ausführungen bekannt. So ist beispielsweise mit der DPS 693 845 eine leichte Schutzplatte aus geschichteten Faserstoffen mit Kunstharzen als Bindemittel vorgeschlagen worden, welche zur Erhöhung der Beschußfestigkeit mit Bewehrungseinlagen aus Stahldrahtgewebe kleiner Maschengröße versehen sind. Mit der DAS 1 042 430 ist eine Panzerplatte bekannt geworden, die in gestalt eines metallischen Wabenblockteiles ausgebildet ist, dessen Waben mit einem nachgiebigen Werkstoff, zum Beispiel einem Elastomer, ausgefüllt sind. Die DAS 1 113 399 sieht eine mehrschichtige Panzerung für Fahrzeuge vor, bei der zwischen zwei Stahlplatten eine Kunststoffschicht und zusätzlich eine äußere, oberflächenverfestigte Stahlplatte angeordnet sind. Es hat sich jedoch herausgestellt, daß die bekannten aus Metall und Kunststoff bestehenden Panzerungen nicht an die sie gestellten Anforderungen hinsichtlich eines möglichst leichten Gewebes einerseits und der Durchschußsicherheit andererseits erfüllen.Armouring made of combinations of metal with plastic is available in various ways Executions known. For example, the DPS 693 845 is a lightweight protective plate made of layered fibers with synthetic resins as binders have been proposed, which to increase the bullet resistance with reinforcement inserts made of steel wire mesh smaller mesh size are provided. The DAS 1 042 430 is an armor plate became known that in the form of a metallic honeycomb block part educated whose honeycomb is made of a flexible material, for example an elastomer, are filled out. DAS 1 113 399 sees multilayer armor for vehicles before, with a plastic layer and an additional one between two steel plates outer, surface-hardened steel plate are arranged. However, it turned out that the known armor made of metal and plastic does not adhere to the on the one hand, they set requirements with regard to a fabric that is as light as possible and the bulletproof security on the other hand.
Die Erfindung hat sich daher zur Aufgabe gestellt, eine aus einer Stahl/Kunststoff-Kombination bestehende Panzerung zu schaffen, die ein verhältnismäßig geringes Gewicht hat und weitgehend beschußsicher ist, so daß sie besonders für den Schutz von zivilen Fahrzeugen, zum Beispiel von Geldtransportwagen verwendet werden kann.The invention has therefore set itself the task of one from a Steel / plastic combination to create existing armor that is proportionate has low weight and is largely bulletproof, so that it is particularly suitable for used for the protection of civil vehicles, for example cash-in-transit vehicles can be.
Gelöst wird die Aufgabe dadurch, daß jede Kunststoffschicht aus einer oder mehreren hintereinander angeordneten Platten aus Polyamid besteht, vorzugsweise mit einem eingelagerten Gewebe auf der Basis von Synthesefaser oder Metalifaser, Vliesen aus diesen Werkstoffen oder dergleichen. Es hat sich nämlich überraschenderweise gezeigt, daß'Polyamide, deren teilkristalliner Anteil durch eine entsprechende thermische Nachbehandlung im Anschluß an den Herstellungsprozeß der Platten gesteigert wird, ein ausgezeichnetes Dämpfungsverhalten gegenüber eindringenden Geschossen aufweisen, Dieses geschoßeindringhemmende gute Dämpfungsverhalten kann noch dadurch verbessert werden, daß ein Polyamid verwendet wird, welches aus einem Mischpolymid aus Caprolactam und Laurinlactam oder Caprolactam und Capryllactam gebildet ist, wobei die Anteile der langkettigen Lactame zwischen 10 bis 90 5', vorzugsweise zwischen 15 bis 30 s liegen, bzw. betragen.The object is achieved in that each plastic layer consists of one or several panels arranged one behind the other made of polyamide, preferably with an embedded fabric based on synthetic fiber or metal fiber, Nonwovens made from these materials or the like. It turned out to be surprising shown that'Polyamides, whose partially crystalline portion by a corresponding thermal Post-treatment is increased following the manufacturing process of the panels, have excellent damping behavior against penetrating projectiles, This good damping behavior, which prevents bullet penetration, can be further improved as a result be that a polyamide is used, which is made of a mixed polymide of caprolactam and laurolactam or caprolactam and caprylic lactam is formed, the proportions of the long-chain lactams between 10 and 90 5 ', preferably between 15 and 30 s lie or amount.
Gemäß dem weiteren Merkmal der Erfindung ist es zweckmäßig, die Polyamidplatte in Gestalt einer Wellplatte auszubilden0 Das hat gegenüber einer ebenen Platte den Vorteil, daß aufgrund der beim Abkühlungsprozeß nach Herstellung einer Wellplatte in dieser sich ergebenden Spannungsverhältnissen in Verbindung mit der bei einer Wellplatte gegenüber einer ebenen Platte gegebenen, eine höhere Dämpfung aufweisende größere Oberfläche, diese Platte eine erhöhte Sicherheit gegenüber Beschuß aufweist. Das gilt umsomehr, wenn die Wellplatte in einfacher Weise dadurch gebildet ist, daß in Schleuderguß hergestellte und dadurch gut verdichtete Rohre aufgeschnitten und diese dickwandigen Rohrschalen ihrer Form entsprechend dicht aneinandergelegt werden.According to the further feature of the invention, it is expedient to use the polyamide plate in the form of a corrugated sheet0 This has the opposite of a flat sheet Advantage that due to the cooling process after production of a corrugated sheet in this resulting tension in connection with the one Corrugated sheet compared to a flat sheet, exhibiting higher attenuation larger surface, this plate has an increased security against bombardment. This is all the more true if the corrugated sheet is formed in a simple manner by that made in centrifugal casting and thus well-compacted pipes cut open and these thick-walled pipe shells are placed close together according to their shape will.
In der Zeichnung sind Ausführungsbeispiele der Erfindung schematisch im Querschnitt dargestellt.Exemplary embodiments of the invention are shown schematically in the drawing shown in cross section.
Im einfachsten Fall besteht die Panzerung aus der ebenen Polyamidplatte 1, die beidseitig von je einer Stahlplatte 2 abgedeckt ist.In the simplest case, the armor consists of a flat polyamide plate 1, which is covered on both sides by a steel plate 2.
Abbildung 2 veranschaulicht diese Platte in einer Sandwich-Bauweise.Figure 2 illustrates this panel in a sandwich construction.
Die Panzerung kann auch in Form einer gewellten Polyamidplatte 3 hergestellt sein mit einer beidseitigen Abdeckung aus einer gewellten Stahlplatte 4 (Abb. 3).The armor can also be made in the form of a corrugated polyamide plate 3 be with a double-sided cover made of a corrugated steel plate 4 (Fig. 3).
Eine weitere Ausführung ergibt sich mit Abbildung 4. In diesem Fall besteht die Wellplatte aus den dicht aneinandergefügten Rohrschalen 5, welche zwischen den beiden Stahlplatten 6 angeordnet sind.Another version is shown in Figure 4. In this case consists of the corrugated sheet of the tightly joined pipe shells 5, which between the two steel plates 6 are arranged.
Bei einem Versuch wurde eine 20 mm dicke ebene Polyamidplatte, welche mit einer 1 mm dicken Stahlplatte aus ST 37 bewehrt war, aus einer Entfernung von 3 Metern mit einem Revolver, Kaliber 357 Magnum, Teilmantelgeschoß, beschossen, Hierbei ergaben sich sowohl beim Einzelbeschuß wie bei Salven keine DurchschUsse, Das gleiche Ergebnis wurde mit einer Maschinenpistole, 9 mm Para, ebenfalls bei Einzelbeschuß und bei Salvenfeuer erzielt.In one test, a 20 mm thick flat polyamide plate, which was reinforced with a 1 mm thick steel plate made of ST 37, from a distance of 3 meters with a revolver, caliber 357 Magnum, semi-jacketed bullet, shot at, Here resulted neither with single fire nor with volleys Bullets, the same result was obtained with a submachine gun, 9 mm para, also scored with single fire and volley fire.
