Abstract

Description

Gegenstand der Erfindung ist ein Verbundwerkstoff für Armor Piercing Incendiary (API) und Incendiary Geschosse, sowie ein entsprechendes Herstellverfahren.The invention relates to a composite material for armor piercing incendiary (API) and incendiary projectiles, as well as a corresponding manufacturing process.

API Geschosse gehören seit langer Zeit zum Stand der Technik und werden beispielsweise in der US 1380773 A beschrieben. Verwendet werden sie zur Treffermarkierung durch Licht und zum Inbrandsetzen von entzündlichen Gegenständen. Wenn also ein Projektil auftrifft, soll es einen Lichtblitz emittieren. Besonders bekannt sind vier unterschiedliche Systeme:
Dazu gehört das Frangible Armor Piercing (FAP) System, eine Munition, welche einen mehrteiligen Aufbau besitzt, der insbesondere aber nicht ausschliesslich aus Metallpulver besteht. Dieses Metallpulver (Titan oder Zirkonium) ist in Epoxidharz eingebettet und bildet so einen brennbaren Teil, der beim Aufprall ein helles Licht emittiert (so zum Beispiel in US 5299501 A ).API bullets have been state of the art for a long time and are used, for example, in the US 1380773 A described. They are used to mark hits with light and to set flammable objects on fire. So when a projectile hits it is supposed to emit a flash of light. Four different systems are particularly well known:
This includes the Frangible Armor Piercing (FAP) system, an ammunition that has a multi-part structure, which in particular, but not exclusively, consists of metal powder. This metal powder (titanium or zirconium) is embedded in epoxy resin and thus forms a combustible part that emits a bright light upon impact (as for example in US 5299501 A ).

Pyrotechnische Systeme sind bei grösseren Kalibern (militärisches Mittelkaliber) weit verbreitet. Sie enthalten einen pyrotechnischen Satz, welcher beim Auftreffen initiiert wird und ein helles Licht emittiert. Diese pyrotechnischen Sätze bestehen meist aus einem Anteil an Magnesium oder Aluminium und einem Anteil an Sauerstofflieferanten in Feststoffform (siehe beispielsweise die US 3028808 A ).Pyrotechnic systems are widespread for larger calibers (military medium caliber). They contain a pyrotechnic charge, which is initiated on impact and emits a bright light. These pyrotechnic charges usually consist of a proportion of magnesium or aluminum and a proportion of oxygen suppliers in solid form (see for example the US 3028808 A ).

Bei militärischer Kleinkaliber Munition sind Systeme bekannt, welche ausschliesslich einen Brennstoff enthalten (z. B. in US 4112846 A ). Die Kleinkaliber API Munition ist mit einer Spitze versehen, welche aus Titan aufgebaut ist und ist oftmals aus dem Vollen spanend bearbeitet. Diese Titanspitze wird beim Aufprall durch die Reibung erhitzt. Diese Reibungswärme reicht aus, um das Titan zu entzünden. Da Titan unter einer hellen Flamme verbrennt, erreicht man so eine genaue Zielpunktmarkierung.In the case of small-caliber military ammunition, systems are known which contain only one fuel (e.g. in US 4112846 A ). The small caliber API ammunition is provided with a tip, which is made of titanium and is often machined from the solid. This titanium tip is heated by friction on impact. This frictional heat is enough to ignite the titanium. Since titanium burns under a bright flame, an accurate target mark is achieved.

Neben der Zielpunktmarkierung können auch absichtlich leicht zu entzündende Gegenstände in Brand gesetzt werden.In addition to marking the target point, objects that are easily ignited can also be set on fire.

Multi Purpose Geschosse zählen auch zu den pyrotechnischen Systemen, besitzen aber neben einer leuchtenden Pyrotechnik auch einen Satz der explodiert. Dadurch erreicht man eine Kombination aus Zielpunktmarkierung, Brandsatz, Schrapnellproduktion und Penetrationseffekt. Diese Projektilart hat aber den grossen Nachteil, dass der erforderliche mehrschichtige Aufbau zusätzlich mit relativ hohen Herstellkosten verbunden ist ( US 2564870 A ).Multi-purpose projectiles also belong to the pyrotechnic systems, but in addition to luminous pyrotechnics they also have a set that explodes. This achieves a combination of target point marking, incendiary device, shrapnel production and penetration effect. However, this type of projectile has the major disadvantage that the multilayer structure required is also associated with relatively high manufacturing costs ( US 2564870 A ).

API Geschosse im Kleinkaliber Bereich sind meist dreiteilig aufgebaut. Der Schuh besteht vorzugsweise aus einem Drehteil aus einer Messinglegierung. Dieser Schuh steht in Kontakt mit dem Lauf. Deshalb ist hierbei eine hohe Duktilität gefordert. Der Schuh darf den Stahllauf nicht beschädigen. Im Zentrum eines bevorzugt ausgestalteten Projektils ist ein harter Kern eingelegt. Dieser besteht aus einer Stahl oder Wolframlegierung. Der Zweck des Hartkerns ist es, die Penetration sicherzustellen.API bullets in the small caliber area are usually constructed in three parts. The shoe preferably consists of a turned part made of a brass alloy. This shoe is in contact with the barrel. Therefore, a high ductility is required here. The shoe must not damage the steel barrel. A hard core is inserted in the center of a preferably configured projectile. This consists of a steel or tungsten alloy. The purpose of the hard core is to ensure penetration.

Den Incendiary Anteil bei diesen Geschossen liefert die Titanspitze. Die Titanspitze besteht in der Regel aus Vollmaterial und hat oft einen relativ komplexen Aufbau, da es sich an der Spitze befindet und immer noch genug Platz für den langen Hartkern bereitstellen soll. Es ist aber auch denkbar, Incendiary Geschosse ohne Hartkern zu fertigen. Hinzu kommt, dass der Aufbau in Vollmaterial-Titan marktwirtschaftlich fraglich ist, da die Materialeigenschaften des relativ teuren rein-Titans in keiner Weise ausgenutzt werden. Für den Incendiary Effekt sind weder die Duktilität noch die geringe Dichte entscheidend. Auch die hervorragende Korrosionsbeständigkeit hat nur eine untergeordnete Relevanz. Aufgrund der teils komplizierten Innengeometrie ist das Volumen, das spanend abgetragen werden muss, relativ groß. Der Grund für die Verwendung des Materials ist dessen Brennbarkeit.The incendiary part of these bullets is provided by the titanium tip. The titanium tip is usually made of solid material and often has a relatively complex structure, as it is located at the tip and should still provide enough space for the long hard core. But it is also conceivable to manufacture incendiary projectiles without a hard core. In addition, the structure in solid titanium is questionable from a market point of view, since the material properties of the relatively expensive pure titanium are not exploited in any way. Neither ductility nor low density are decisive for the incendiary effect. The excellent corrosion resistance is also only of subordinate relevance. Because of the sometimes complicated Inside geometry, the volume that has to be removed by cutting is relatively large. The reason for using the material is its flammability.

Der vorliegenden Erfindnung lag deshalb die Aufgabe zugrunde, ein Material zu finden, das kostengünstiger ist und ein Verfahren zu finden, das materialsparender ist. Bei der Herstellung von Titan und auch Magnesium zu einem Halbzeug besteht das Ausgangsmaterial aus einer schlammartigen Struktur, die einfach zu Pulver verarbeitet werden kann. Dies ist auch der Grund, warum die Pulver (Präkursor Material) der jeweiligen Materialien vergleichsweise preisgünstig sind. Erfindungsgemäß ist daher besonders optimal, eine Methode zu verwenden, bei welcher die Spitzen der Projektile so angefertigt werden, dass Pulvermaterial verwendet werden kann. Dadurch reduziert sich der Abfall signifikant, obwohl die Konturen immer noch komplex sein können. Beim Produktionsprozess kann die Matrix des Verbundwerkstoffes genutzt werden, um die Teilstücke Geschossschuh und Kern miteinander dauerhaft zu verbinden .Um das Geschoss möglichst günstig zu halten sollte die Spitze direkt in der vorher definierten und gewünschten Farbe erhältlich sein, ohne dass ein zusätzlicher Färbevorgang notwendig wäre.The present invention was therefore based on the object of finding a material that is more cost-effective and of finding a method that is more material-saving. When manufacturing titanium and magnesium into a semi-finished product, the starting material consists of a sludge-like structure that can easily be processed into powder. This is also the reason why the powders (precursor material) of the respective materials are comparatively inexpensive. According to the invention, it is therefore particularly optimal to use a method in which the tips of the projectiles are made so that powder material can be used. This significantly reduces waste, although the contours can still be complex. During the production process, the matrix of the composite material can be used to permanently connect the sections of the bullet shoe and core. To keep the bullet as cheap as possible, the tip should be available in the previously defined and desired color without the need for an additional dyeing process.

Beim zu schützenden Projektil wird die ungünstige Materialausnutzung gelöst, indem ein Metallpulver, bevorzugt Titan- oder Magnesiumpulver in eine Polymermatrix eingebettet wird. Der Polymer-Verbundwerkstoff kann durch Spritzpressen oder andere geeignete Formgebungsverfahren geformt werden. Als Matrixpolymer kann ein Duroplast oder Thermoplast verwendet werden. Das Metallpulver erfüllt hierbei die Funktion des Brandssatzes, die Matrix dient als Träger und zugleich als Befestigungsmaterial für die beiden anderen Teile (Hartkern und Geschossschuh). Auch eine Verbindung zwischen dem Hauptprojektil und dem Polymerverbundwerkstoff ist denkbar, was aber nur für die Incendiary Variante in Betracht kommt. Der Aufbau eines erfindungsgemäßen Projektils ist aus Fig. 1 ersichtlich.In the case of the projectile to be protected, the unfavorable material utilization is solved by embedding a metal powder, preferably titanium or magnesium powder, in a polymer matrix. The polymer composite can be molded by transfer molding or other suitable shaping methods. A thermoset or thermoplastic can be used as the matrix polymer. The metal powder fulfills the function of the incendiary device, the matrix serves as a carrier and at the same time as fastening material for the other two parts (hard core and bullet shoe). A connection between the main projectile and the polymer composite material is also conceivable, but this is only possible for the incendiary variant. The structure of a projectile according to the invention is shown in FIG.

Durch orientierende Tests wurde herausgefunden, dass es überraschenderweise reicht, einen Metall- Polymer-Verbundwerkstoff zu verwenden, um den gewünschten Lichteffekt zu generieren. Der Polymer-Metallverbund besteht bevorzugt zu mindestens 50 Volumenprozent aus einem Metallpulver. Das Metallpulver wird vorzugsweiseausgewählt aus der Gruppe, bestehend aus Titan, Magnesium, Aluminium, Zirkon oder beliebigen Mischungen davon, bevorzugt besteht das Metall pulver aus Titan oder Magnesium. Die Polymermatrix besteht bevorzugt aus einem thermoplastischen Industriekunststoff, beispielsweise Polyethereterketon (PEEK) oder einem anderen Industriekunststoff. PEEK ist aufgrund des breiten Temperaturbandes, in demdas Produkt eingesetzt werden kann, für die Anwendung besonders geeignet.Orientative tests have found that, surprisingly, it is sufficient to use a metal-polymer composite material in order to generate the desired light effect. The polymer-metal composite preferably consists of at least 50 percent by volume of a metal powder. The metal powder is preferably selected from the group consisting of titanium, magnesium, aluminum, zirconium or any mixtures thereof, preferably the metal powder consists of titanium or magnesium. The polymer matrix preferably consists of a thermoplastic industrial plastic, for example polyetherether ketone (PEEK) or another industrial plastic. PEEK is particularly suitable for this application because of the wide temperature range in which the product can be used.

Bevorzugt wird die Spitze des Geschosses direkt auf den Geschossschuh und den Hartkern gespritzt. Damit eine verbesserte Verbindung entsteht, können Geschosskern und Geschossschuh mit einer rauen Oberfläche, Kerben oder Radialnuten versehen werden. Idealerweise kann das Precursor Stück (Fig. 2), bestehend aus Geschossschuh mit dem darin befindlichen Kern, in das Spritzgusswerkzeug eingelegt werden und von der Spitze her umgossen werden. Dadurch können mehrere Arbeitsschritte vereinfacht oder eingespart werden, beispielsweise ist das Einpressen mit einer Presspassung, um das Precursor Stück zu erhalten, nicht mehr notwendig. Das Aufsetzen der Geschossspitze fällt ebenfalls weg und durch das Spritzgiessen der Geschossspitze wird eine zusätzliche Abdichtung hinfällig.The tip of the bullet is preferably injected directly onto the bullet shoe and the hard core. So that an improved connection is created, the bullet core and bullet shoe can be provided with a rough surface, notches or radial grooves. Ideally, the precursor piece (FIG. 2), consisting of a bullet shoe with the core located therein, can be inserted into the injection molding tool and cast around from the tip. As a result, several work steps can be simplified or saved; for example, pressing in with a press fit to obtain the precursor piece is no longer necessary. There is also no need to put on the bullet tip and the injection molding of the bullet tip eliminates the need for an additional seal.

In einer anderen Ausführungsform kann ein modularer Aufbau in Betracht gezogen werden. Die im Einzelnen produzierte Polymer-Verbund-Geschossspitze kann dabei mit einem Schnappverschluss, einem Bajonettverschluss oder einem Pressverschluss auf dem Precursor befestigt werden. Dadurch wird eine dezentrale Fertigung möglich. Auch eine Ausführungsform mit einer kurz vor dem Einsatz abänderbaren Geschosspitzenkonfiguaration ist dadurch möglich. Es ist in einer besonders hervorzuhebenden Ausführungsform möglich, wahlweise eine Kunststoffspitze ohne Metallinhalt oder eine Spitze mit unterschiedlichen Mischungen einzusetzen. Dadurch kann eine einzige Geschosskonstruktion wahlweise als AP Munition oder API Munition verwendet werden.In another embodiment, a modular structure can be considered. The individually produced polymer composite bullet tip can be attached to the precursor with a snap lock, a bayonet lock or a press lock. This makes it a decentralized one Manufacturing possible. An embodiment with a projectile tip configuration that can be changed shortly before use is also possible. In an embodiment that is to be particularly emphasized, it is possible to use either a plastic tip without metal content or a tip with different mixtures. This means that a single projectile construction can be used either as AP ammunition or API ammunition.

Industriekunststoffe sind verschiedenfarbig als Granulat erhältlich. Somit ist auch eine simple Markierung und farbliche Anpassung möglich. Als Metallpulver eigenen sich Korngrössen von 0,02 mm bis 0,4 mm. Grundsätzlich entsteht dabei nur wenig Metallabfall. Dies macht die Konstruktion ökonomisch und ökologisch wertvoll.Industrial plastics are available in different colors as granules. A simple marking and color adjustment is thus also possible. Grain sizes of 0.02 mm to 0.4 mm are suitable as metal powder. In principle, there is little metal waste. This makes the construction economically and ecologically valuable.

Das Funktionsprinzip für den Lichtblitz erklärt sich wie folgt. Durch den kurzzeitdynamischen Aufprall der Spitze reagiert der Kunststoff sprödbruchanfällig, so dass der Kunststoff-Metall-Verbund ähnlich einer Keramik zerbricht. Dabei werden die Metallpulverpartikel freigesetzt. Durch die Aufprallreibung werden die Partikel zusätzlich aufgewärmt und entzünden sich z. B. bei Magnesium bereits nach kürzester Zeit selbst. Das Titan benötigt zwar mehr Energie bis die Selbstzündtemperatur erreicht ist, weshalb sich auch ein verändertes Feuerbild zeigt, aber eine Entzündung beim Aufprall ist dennoch möglich. Bei Metallpulvergemischen kann daher ein gewünschter Effekt erzielt werden, beispielsweise eine Flammfärbung durch Zusätze von anderen Elementen ist denkbar. Dafür kommen insbesondere die Alkali- und Erdalkalimetalle in Betracht, die vielfach eine charakteristische Flammfärbung aufweisen. Insbesondere geeignet sind Zusätze von Kalium, Natrium, Barium, Calcium, Lithium, Bor, Strontium.The functional principle for the light flash is explained as follows. Due to the short-term dynamic impact of the tip, the plastic reacts prone to brittle fracture, so that the plastic-metal bond breaks like a ceramic. The metal powder particles are released in the process. The particles are additionally warmed up by the impact friction and ignite e.g. B. with magnesium itself after a very short time. The titanium needs more energy until the auto-ignition temperature is reached, which is why the fire pattern is different, but ignition on impact is still possible. In the case of metal powder mixtures, a desired effect can therefore be achieved, for example flame coloring through the addition of other elements is conceivable. The alkali and alkaline earth metals, which often have a characteristic flame color, are particularly suitable for this. Additions of potassium, sodium, barium, calcium, lithium, boron and strontium are particularly suitable.
