Description

Chaleco híbrido.Hybrid vest

La invención se refiere a un chaleco antibala con factor de protección SK 1 y un peso por unidad de superficie entre 3,7 y 4,1 kg/m^{2} y que contiene una pila de paquetitos flexibles, que están constituidos por capas unidireccionales, que se componen en su mayor parte de un primer tipo de fibra, a saber polibenzoxazol (PBO), en donde las fibras discurren fundamentalmente en paralelo en una capa unidireccional y forman con las fibras de la capa contigua un ángulo, que es mayor que 0 grados.The invention relates to a bulletproof vest with protection factor SK 1 and a weight per unit area between 3.7 and 4.1 kg / m2 and containing a stack of packages flexible, which are made up of unidirectional layers, which they consist mostly of a first type of fiber, namely polybenzoxazole (PBO), where the fibers run fundamentally in parallel in a unidirectional layer and form with the fibers of the contiguous layer an angle, which is greater than 0 degrees.

Un chaleco de esta clase es conocido por el documento WO 97 49546A, que constituye un fundamento para el preámbulo de la reivindicación 1.A vest of this class is known by the WO 97 49546A, which constitutes a basis for the preamble of claim 1.

Se conocen en el mercado chalecos antibala que están constituidos por capas de fibras de PBO unidireccionales y que se caracterizan por un factor de protección SK 1, es decir amortiguador de los disparos contra munición con camisa de acero Geco de 9 mm a 410 m/s. Para la consecución del factor de protección SK 1 es necesario un peso por unidad de superficie de aprox. 3,7 kg/m^{2}.Bulletproof vests are known on the market that are made up of layers of unidirectional PBO fibers and are characterized by a SK 1 protection factor, that is, shock absorber against ammunition with a 9 mm Geco steel jacket at 410 m / s . To achieve the protection factor SK 1, a weight per unit area of approx. 3.7 kg / m2.

El inconveniente de un chaleco de este tipo reside en los altos costes de los paquetitos de capas unidireccionales de fibra PBO.The inconvenience of such a vest resides in the high costs of layer packages Unidirectional PBO fiber.

El objetivo de la invención es el desarrollo de un chaleco, que contiene como máximo 2,6 kg/m^{2} de capas unidireccionales de fibra PBO, en el cual se mantiene válidamente el factor de protección SK 1 y el peso por unidad de superficie aumenta en no más de 10%.The objective of the invention is the development of a vest, which contains a maximum of 2.6 kg / m2 of layers Unidirectional PBO fiber, in which the protection factor SK 1 and the weight per unit area increases in no more than 10%.

Este objetivo se consigue de tal modo que el chaleco está constituido en el lado de disparo por paquetitos de capas de un segundo tipo de fibra, en el cual estos paquetitos de capas del segundo tipo de fibra constituyen 40-80% en peso del chaleco y contienen principalmente fibras de aramida o HPPE. Para la preparación de las capas del segundo tipo de fibras se da preferencia a fibras de HPPE.This objective is achieved in such a way that the vest is constituted on the firing side by packets of layers of a second type of fiber, in which these packets of layers of the second type of fiber constitute 40-80% by weight of the vest and contain mainly aramid fibers or HPPE. For the preparation of the layers of the second type of fibers, gives preference to HPPE fibers.

De este modo se consigue producir un chaleco que contiene, con un peso por unidad de superficie de 3,7 a 4,1 kg/m^{2} y un factor de protección SK 1, como máximo 2,46 kg/m^{2} de PBO UD.In this way it is possible to produce a vest that Contains, with a weight per unit area of 3.7 to 4.1 kg / m2 and a protection factor SK 1, at most 2.46 kg / m2 of PBO UD.

El peso por unidad de superficie se define en esta memoria como el peso del chaleco por metro cuadrado.The weight per unit area is defined in This memory as the weight of the vest per square meter.

Sorprendentemente, se ha encontrado que es necesario en el caso de la sustitución de PBO por aramida o HPPE en el lado de disparo del chaleco menos aramida o HPPE, que el que habría sido de esperar teniendo en cuenta el peso de un chaleco completo de aramida o HPPE con factor de protección SK 1.Surprisingly, it has been found that it is necessary in the case of replacing PBO with aramid or HPPE on the firing side of the less aramid or HPPE vest, than would have been expected considering the weight of a full aramid vest or HPPE with protection factor SK 1.

Los paquetitos de capas del segundo tipo de fibra constituyen 40-80 por ciento en peso del chaleco. Para un porcentaje en peso inferior a 40%, la ventaja en precio se hace demasiado pequeña en el caso de un chaleco completo de PBO. Si el porcentaje en peso llega a ser mayor que 80%, entonces es necesario para la consecución del factor de protección SK 1 una cantidad tan grande de aramida o HPPE, que el peso por unidad de superficie del chaleco sobrepasa el valor de 4,1 kg/m^{2}.Layered packages of the second type of fiber constitute 40-80 percent by weight of vest. For a weight percentage of less than 40%, the advantage in price becomes too small in the case of a full vest of PBO. If the weight percentage becomes greater than 80%, then it is necessary to achieve the protection factor SK 1 a such a large amount of aramid or HPPE, that the weight per unit of vest surface exceeds the value of 4.1 kg / m2.

Bajo fibras HPPE se entienden fibras estiradas de polietileno de peso molecular ultraelevado. Las fibras de polietileno de peso molecular ultraelevado se componen de polietileno con un peso molecular medio de al menos 500.000 kg/kmol. El peso molecular es preferiblemente mayor que 2.000.000 kg/kmol.Under HPPE fibers, stretched fibers are understood of ultra-high molecular weight polyethylene. Fibers of ultra-high molecular weight polyethylene are made up of polyethylene with an average molecular weight of at least 500,000 kg / kmol. The molecular weight is preferably greater than 2,000,000 kg / kmol

La abreviatura "protección SK 1" significa que el chaleco responde a las exigencias establecidas por la norma de la Clase de Protección 1 Alemana.The abbreviation "protection SK 1" means that the vest responds to the requirements established by the standard of German Protection Class 1.

Por lo general, un chaleco está constituido por una pila de paquetitos de fibras fuertes. Estos paquetitos pueden estar constituidos por dos o más capas de fibras unidireccionales. En este caso, las fibras discurren en su mayor parte en paralelo y forman con las fibras de una capa contigua un ángulo que es mayor que 0 grados. Un paquetito debería estar constituido preferiblemente por dos o cuatro capas.Usually, a vest is made up of a stack of strong fiber packets. These packages can be constituted by two or more layers of unidirectional fibers. In this case, the fibers run mostly in parallel and they form an angle that is greater with the fibers of a contiguous layer that 0 degrees. A package should preferably be constituted by two or four layers.

El chaleco comprende preferiblemente 50-70 por ciento en peso de capas de la segunda clase. De este modo se consigue que el peso se desvíe en menos de 5% del correspondiente a un chaleco que está constituido totalmente por capas de PBO.The vest preferably comprises 50-70 percent by weight of layers of the second class. This allows the weight to deviate by less than 5%. of the corresponding to a vest that is constituted totally by PBO layers.

Bajo "fibras" se entienden en este contexto objetos estirados, cuya longitud es considerablemente mayor que su anchura o su grosor. Las fibras contienen mono- y multifilamentos continuos como fibras cortas o fibras cortadas.Under "fibers" are understood in this context stretched objects, whose length is considerably greater than their width or thickness. Fibers contain mono- and multifilaments continuous as short fibers or cut fibers.

La designación "fibras fuertes" alude en este desarrollo reciente por regla general a fibras con una fuerza de al menos 6 dN/tex, un módulo de al menos 130 dN/tex y una energía de rotura de al menos 8 J/g. Se da preferencia a fibras fuertes, fibras con una fuerza de al menos 10 dN/tex, un módulo de al menos 200 dN/tex y una energía de rotura de al menos 20 J/g. Se da mayor preferencia a fibras con una fuerza de al menos 16 dN/tex, un módulo de al menos 400 dN/tex y una energía de rotura de al menos 27 J/g. Sin embargo, las más preferidas son fibras con una fuerza de al menos 28 dN/tex, un módulo de al menos 1200 dN/tex y una energía de rotura de al menos 40 J/g. Como fibras fuertes son apropiadas tanto fibras de aramida como fibras de HPPE. Se prefieren fibras de HPPE.The designation "strong fibers" refers to this recent development as a rule to fibers with a force of at least 6 dN / tex, a module of at least 130 dN / tex and an energy of breakage of at least 8 J / g. Preference is given to strong fibers, fibers with a force of at least 10 dN / tex, a module of at least 200 dN / tex and a breaking energy of at least 20 J / g. It gets older preference to fibers with a force of at least 16 dN / tex, a module of at least 400 dN / tex and a breaking energy of at least 27 J / g. However, the most preferred are fibers with a force of at least 28 dN / tex, a module of at least 1200 dN / tex and a breaking energy of at least 40 J / g. How strong fibers are appropriate both aramid fibers and HPPE fibers. They prefer HPPE fibers.
