Abstract

An armoured plate, which gives protection from projectiles which are not too powerful, consists of a plate which carries on the side, exposed to shellfire, a layer of elastic material in which a high percentage of hard particles of 0.1-2-6mm dia. of a bullet breaking material (alumina sinter ceramics, boron carbide, other metal carbides), are embedded. The rear plate is made of a bullet retarding material and the plate of a bullet breaking material. Textile fibre tissue (aramide fibres) in the outer areas not covered by hard particles are impregnated with synthetic resin.

Description

Der Erfindung des Hauptpatentes liegt die Aufgabe zugrunde, ein plattenförmiges Panzerelement zu entwickeln, das gegen schwächere Munition ausreichend Schutz bietet, dabei preisgünstig herzustellen und ohne großen Aufwand den zu sichernden Objekten zuzuordnen ist. Das Gewicht soll dabei so gering sein, daß es Fahrzeugen ohne wesentliche Erhöhung des Leergewichtes zuzuordnen ist.The invention of the main patent is based on the object to develop a plate-shaped armor element that against weaker ammunition offers sufficient protection, while being inexpensive to manufacture and to be secured without much effort Is to be assigned to objects. The weight should be like this be small that there are vehicles without a significant increase in Empty weight is to be assigned.

Als besonders zweckmäßige Lösung der Aufgabe hat sich gemäß dem Hauptpatent ein Bauteil erwiesen, das eine Platte aus einem geschoßbrechenden Hartstoff aufweist, auf deren bezüglich des erwartungsgemäß auftretenden Geschosses als Rückseite zu bezeichnenden Seite ein geschoßhemmender Stützstoff angeordnet ist. Als geschoßbrechender Hartstoff besonders geeingnet erweisen sich insbesondere Aluminiumoxid- Sinterkeramik und Borcarbid.A particularly expedient solution to the problem has been found the main patent proved a component that made a plate has a bullet-breaking hard material, on the with regard to the floor as expected Back side to be designated a bullet-resistant support fabric is arranged. As a bullet-breaking hard material  aluminum oxide in particular have proven particularly suitable Sintered ceramics and boron carbide.

Bei einem gemäß dem Hauptpatent erfindungsgemäßen Bauteil hat das Stützgewebe insbesondere die Aufgabe, den durch einen etwaigen Beschuß zerstörten bzw. verformten Hartstoff im Gesamtaufbau zusammenzuhalten. Die Fasern des Stützgewebes haben im Zusammenwirken mit dem Lagenaufbau ein hohes Arbeitsaufnahmevermögen, so daß ein Geschoß, das beim Durchschlagen der Hartstoffpanzerung bereits stark abgebremst wurde, zum Stillstand gebracht werden kann, ohne für hinter der Panzerung befindliche Personen oder Objekte eine Gefahr darzustellen.In one according to the main patent according to the invention The support fabric has the task, in particular, of the component destroyed or deformed by any shelling Holding hard material together in the overall structure. The fibers of the support fabric in cooperation with the layer structure a high work capacity, so that one floor, already strong when the hard material armor penetrates slowed down, can be brought to a standstill, without for people behind the armor or Objects to represent a danger.

Im einzelnen zeichnen sich die gemäß dem Hauptpatent erfindungsgemäß für die Stützschicht vorgeschlagenen Materialien durch relativ hohe Zugfestigkeit und Steifigkeit bei hoher Bruchdehnung aus, was insgesamt zu der wünschenswerten guten geschoßhemmenden Wirkung führt. Hierzu trägt auch die vorgesehene Aufbauweise bei, nämlich zumindest den Hauptteil der Gewebelagen lose zu schichten bzw. zu verkleben, wobei die Klebefestigkeit zwischen den einzelnen Lagen niedrig ist. Specifically, they stand out according to the main patent materials proposed according to the invention for the support layer due to relatively high tensile strength and rigidity high elongation at break out, resulting in the overall desirable good bullet-inhibiting effect. The Intended construction, namely at least the To loosely layer or glue the main part of the fabric layers, the adhesive strength between the individual layers is low is.  

Aufgabe der vorliegenden Erfindung ist eine weitere zweckmäßige Ausgestaltung der Erfindung des Hauptpatentes im Hinblick auf die dort behandelte Aufgabe.Another object of the present invention expedient embodiment of the invention of the main patent with regard to the task covered there.

Hierzu wird erfindungsgemäß vorgeschlagen, daß der Hartstoffplatte, gegebenenfalls mehreren solcher Hartstoffplatten eine zusätzliche Schicht vorgelagert ist, die aus elastischem Material besteht, in welches Hartstoffteilchen mit hohem Füllgrad eingebettet sind. Insbesondere sollen die Hartstoffteilchen eine unterschiedliche Korngröße haben, vorzugsweise im Bereich von 0,1-6 mm.For this purpose, it is proposed according to the invention that the Hardboard, possibly several such hardboards an additional layer is upstream from that elastic material, in which hard material particles are embedded with a high degree of filling. In particular, should the hard material particles have a different grain size have, preferably in the range of 0.1-6 mm.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung schematisch dargestellt, worin bedeuten 1 ein Platte, deren Seite 2 der Gefahr des Beschusses ausgesetzt ist, der durch den Pfeil 3 gekennzeichnet ist, wobei die bezüglich des Beschusses als Rückseite zu bezeichnende Seite 4 mit einem beschußhemmenden Stützstoff 5 versehen ist. Die Platte 1 besteht aus einem geschoßbrechenden Werkstoff. Der Platte 1 ist eine Schicht 5′ vorgelagert, die aus elastischem Material besteht, in welches zu einem hohen Anteil Hartstoffteilchen eingebettet sind. Die Hartstoffteilchen haben unterschiedliche Korngröße im Bereich zwischen 0,1-6 mm.An embodiment of the invention is shown schematically in the drawing, in which 1 denotes a plate, the side 2 of which is exposed to the risk of fire, which is indicated by the arrow 3 , the side 4 to be referred to as the rear side of the fire with a bullet-resistant support material 5 is provided. The plate 1 consists of a bullet-breaking material. The plate 1 is a layer 5 ' upstream, which consists of elastic material, in which a high proportion of hard material particles are embedded. The hard material particles have different grain sizes in the range between 0.1-6 mm.
