Abstract

The armored protective vest, incorporating layers of flexible packages of fibers of a first type, is constructed on its inner or outer side of layers of packages containing fibers of a second type and forming 40-80% of the total weight of the vest. Materials for fibers of the second type include aramide and HPPE. Packages of fibers consisting of these materials are in fact located on the outer side of the vest.

Description

Die Erfindung betrifft eine ballistische Weste mit Schutzfakton SK 1 und einem Oberflächengewicht zwischen 3,7 und 4,1 kg/m2 und die einen Stapel flexibler Päckchen enthält, die aus unidirektionalen Schichten zusammengesetzt sind, bestehend größtenteils aus einem ersten Fasertyp, nämlich Polybenzoxazol (PBO), wobei die Fasern in einer unidirektionalen Schicht hauptsächlich parallel verlaufen und zu den Fasern der benachbarten Schicht einen Winkel bilden, der größer ist als 0 Grad.The invention relates to a ballistic vest with protection factor SK 1 and a surface weight between 3.7 and 4.1 kg / m 2 and which contains a stack of flexible packets, which are composed of unidirectional layers, consisting largely of a first type of fiber, namely polybenzoxazole ( PBO), the fibers in one unidirectional layer running mainly parallel and forming an angle to the fibers of the adjacent layer which is greater than 0 degrees.

Ballistische Westen, die aus unidirektionalen PBO-Faserschichten bestehen und sich durch einen SK1-Schutzfaktor auszeichnen, sind dem Markt bekannt. Zur Erlangung des SK 1-Schutzfaktors ist ein Oberflächengewicht von ca. 3,7 kg/m2 erforderlich.Ballistic vests, which consist of unidirectional PBO fiber layers and are characterized by an SK1 protection factor, are known to the market. A surface weight of approx. 3.7 kg / m 2 is required to obtain the SK 1 protection factor.

Der Nachteil einer solchen Weste liegt in den hohen Kosten für Päckchen von unidirektionalen Schichten aus PBO-Faser.The disadvantage of such a vest is the high cost of Pack of unidirectional layers of PBO fiber.

Das Ziel der Erfindung ist die Entwicklung einer Weste, die höchstens 2,6 kg/m2 unidirektionale Schichten aus PBO-Faser enthält, wobei der SK 1-Schutzfaktor gewahrt bleibt und das Oberflächengewicht um nicht mehr als 10% zunimmt.The aim of the invention is to develop a vest which contains at most 2.6 kg / m 2 unidirectional layers of PBO fiber, the SK 1 protection factor being maintained and the surface weight increasing by no more than 10%.

Dieses Ziel wird dadurch erreicht, dass die Weste an Körperoder Schussseite aus Päckchen von Schichten eines zweiten Fasertyps besteht, dass diese Päckchen von Schichten des zweiten Fasertyps 40-80 Gewichtsprozent der Weste bilden und vornehmlich Aramid- oder HPPE-Fasern enthalten, wobei sich die Päckchen von Aramid- oder HPPE-Schichten an der Schussseite der Weste befinden. Bei der Herstellung der Schichten des zweiten Fasertyps verdienen HPPE-Fasern den Vorzug.This goal is achieved by having the vest on body or Weft side consists of packets of layers of a second fiber type, that these packets of layers of the second fiber type 40-80 Weight percent of the vest form and primarily aramid or HPPE fibers included, with the packets of aramid or HPPE layers on the On the weft side of the vest. When making the layers of the second Fiber types deserve preference for HPPE fibers.

So wird erreicht, dass eine Weste entsteht, die bei einem Oberflächengewicht von 3,7 bis 4,1 kg/m2 und einem SK 1-Schutzfaktor höchstens 2,46 kg/m2 PBO UD enthält.The result is that a vest is created which, with a surface weight of 3.7 to 4.1 kg / m 2 and an SK 1 protection factor, contains a maximum of 2.46 kg / m 2 PBO UD.

Oberflächengewicht ist hier definiert wie das Gewicht der Weste pro Quadratmeter.Surface weight is defined here like the weight of the vest per square meter.

Wie sich überraschenderweise herausstellte, benötigt man bei der Substitution von PBO durch Aramid oder HPPE an der Körperseite der Weste weniger Aramid oder HPPE, als angesichts des Gewichts einer kompletten Aramid- bzw. HPPE-Weste mit SK 1-Schutzfaktor zu erwarten gewesen wäre. Die Päckchen von Schichten des zweiten Fasertyps bilden 40-80 Gewichtsprozent der Weste. Bei einem Gewichtsprozentsatz unter 40% fällt der Preisvorteil im Falle einer kompletten PBO-Weste zu gering aus. Liegt der Gewichtsprozentsatz höher als 80%, so benötigt man zur Erlangung des SK 1-Schutzfaktors eine so große Menge Aramid oder HPPE, dass das Oberflächengewicht der Weste den Wert von 4,1 kg/m2 übersteigt.Surprisingly, it was found that the substitution of PBO with aramid or HPPE on the body side of the vest requires less aramid or HPPE than would have been expected given the weight of a complete aramid or HPPE vest with SK 1 protection factor. The packs of layers of the second fiber type make up 40-80 percent by weight of the vest. With a weight percentage below 40%, the price advantage in the case of a complete PBO vest is too small. If the weight percentage is higher than 80%, the amount of aramid or HPPE required to obtain the SK 1 protection factor is such that the surface weight of the vest exceeds 4.1 kg / m 2 .

Unter HPPE-Fasern versteht man gestreckte ultrahohe Molekular-Polyethylenfasern. Ultrahohe Molekular-Polyethylenfasern bestehen aus Polyethylen mit einem durchschnittlichen Molgewicht von mindestens 500 000 kg/kmol. Das Molgewicht beträgt vorzugsweise mehr als 2 000 000 kg/kmol.HPPE fibers are stretched ultra-high Molecular polyethylene fibers. Ultra high molecular polyethylene fibers exist made of polyethylene with an average molecular weight of at least 500,000 kg / kmol. The molecular weight is preferably more than 2,000,000 kg / kmol.

Das Kürzel "SK 1-Schutz" bedeutet, dass die Weste den durch die Norm der Deutschen Schutzklasse 1 gestellten Anforderungen entspricht.The abbreviation "SK 1-Schutz" means that the vest passes through the standard of German protection class 1 meets the requirements.

Im Allgemeinen besteht eine Weste aus einem Stapel von Päckchen aus starken Fasern. Diese Päckchen können aus zwei oder mehr Schichten unidirektionaler Fasern aufgebaut sein. Dabei verlaufen die Fasern meist parallel und bilden zu den Fasern einer benachbarten Schicht einen Winkel, der größer als 0 Grad ist. Ein Päckchen sollte vorzugsweise aus zwei oder vier Schichten bestehen.Generally, a vest consists of a stack of Package made of strong fibers. These packets can consist of two or more Layers of unidirectional fibers can be built up. The fibers run here mostly parallel and form an angle to the fibers of an adjacent layer, that is greater than 0 degrees. A packet should preferably consist of two or four Layers exist.

Die Weste umfasst vorzugsweise 50-70 Gewichtsprozent Schichten der zweiten Sorte. Dadurch wird erreicht, dass das Gewicht um weniger als 5% von dem einer Weste abweicht, die ganz aus PBO-Schichten zusammengesetzt ist.The vest preferably comprises 50-70 percent by weight Layers of the second variety. This ensures that the weight is less than 5% from a vest made entirely of PBO layers is composed.

Unter "Fasern" verstehen wir hier gestreckte Objekte, deren Länge bedeutend größer ist als ihre Breite oder Stärke. Fasern enthalten kontinuierliche Mono- und Multifilamente wie Stapel- oder Schnittfasern.By "fibers" we mean stretched objects, their Length is significantly greater than its width or thickness. Contain fibers continuous mono- and multifilaments such as staple or cut fibers.

Die Bezeichnung "starke Fasern" deutet in dieser Neuentwicklung in der Regel Fasern mit einer Stärke von mindestens 6 dN/tex, einem Modulus von mindestens 130 dN/tex und einer Bruchenergie von mindestens 8 J/g an. Den Vorzug verdienen starke Fasern, Fasern mit einer Stärke von mindestens 10 dN/tex, einem Modulus von mindestens 200 dN/tex und einer Bruchenergie von mindestens 20 J/g. Größeren Vorzug verdienen Fasern mit einer Stärke von mindestens 16 dN/tex, einem Modulus von mindestens 400 dN/tex und einer Bruchenergie von mindestens 27 J/g. Den größten Vorzug jedoch verdienen Fasern mit einer Stärke von mindestens 28 dN/tex, einem Modulus von mindestens 1200 dN/tex und einer Bruchenergie von mindestens 40 J/g erwiesen. Als starke Fasern kommen sowohl Aramid- als auch HPPE-Fasern in Frage. Bevorzugt werden HPPE-Fasern.The term "strong fibers" means in this New development usually fibers with a strength of at least 6 dN / tex, a modulus of at least 130 dN / tex and a breaking energy of at least 8 J / g. Strong fibers deserve preference, fibers with one Strength of at least 10 dN / tex, a modulus of at least 200 dN / tex and a breaking energy of at least 20 J / g. Fibers deserve greater preference with a strength of at least 16 dN / tex, a modulus of at least 400 dN / tex and a breaking energy of at least 27 J / g. The greatest advantage however, fibers with a strength of at least 28 dN / tex deserve one Modulus of at least 1200 dN / tex and a breaking energy of at least 40 J / g proven. Both aramid and HPPE fibers come as strong fibers in question. HPPE fibers are preferred.
