Definitions

• the invention relates to a ballistic multilayer material.
• the disadvantage here is that conventional multi-layer materials are relatively heavy and thick and thus reduce the mobility and mobility of the corresponding person.
• the object of the invention is to avoid the aforementioned disadvantages and to provide a multi-layer material that allows good protection values at a reduced weight.
• the multi-layer material comprises at least one textile base layer and at least on one side a laminated by means of an adhesive film.
• an improved cohesion of the multilayer material is given, and it is achieved a higher resistance, in particular at laminated on both sides.
• a layer reduction can be achieved with the same protection as in previously known materials, which allows a reduced weight of the material and better mobility and mobility of the person to be protected.
• Approximately 25% of the layers can thus be saved with the same protective effect in a corresponding protective clothing, which have so far, for example, 24 to 28 layers, and due to the improved material properties, the trauma values by up to about 20 to 25 % be reduced.
• the lower number of layers required cost savings of about 10 to 15% and weight savings and better mobility for the wearer of the protective clothing can be achieved.
• At least one textile base layer can be formed as a woven fabric, a knitted fabric, a knitted fabric or a felt or fleece, so that an adapted textile structure can be realized in accordance with the respective requirement given by the expected projectiles and the like. It is also possible to combine different layers, each with a different textile structure, into a so-called ballistic package.
• the textile base layer can be a material from the group of aramids, such as. B., and / or polyethylene.
• aramids such as. B.
• polyethylene a polyethylene base material is marketed under the name Dyneema.
• the film may comprise at least one layer of polyurethane and / or polyethylene and / or polyamide or of a combination of materials with at least one of these materials.
• the film may have a transverse and / or longitudinal extensibility of 500%, so that an improved load-bearing capacity of the multilayer material results from the interaction of the different material properties of the textile base layer and the elastic film.
• the adhesive may be formed as a thermoplastic adhesive and / or as a crosslinking adhesive, wherein the adhesive may be formed on the basis of polyurethane and / or polyethylene and / or polyamide and / or polyester.
• a ballistic package consisting of a base layer and films laminated on one side or films laminated on both sides
• the individual layers can be formed at least partially or completely uniformly, but the layers can also be be formed differently with respect to at least one or more, but in particular also with respect to all features.
• the connection of the layers can be provided above all in the edge region, but in particular also at points in the surface, in particular with a generous dot pattern, wherein the pattern can be uniform or deviating from one layer to the next.
• the adhesive can be provided in each case selectively and the adhesive dots of superimposed layers can be at least substantially each other distributed differently, so that a relative mobility of the individual layers is maintained to each other.
• the adhesive may be provided in each case grid-shaped and the grid of superimposed layers may at least substantially coincide, but provided offset from each other.
• the invention also relates to a ballistic protective clothing, which may comprise a ballistic multilayer material of the aforementioned type to achieve the aforementioned advantages and in particular to an at least substantial proportion of this ballistic multilayer material can be made.
• At least one laminated layer of the ballistic multilayer material with the film on the outside and the base layer may be provided on the inside.
• the invention further relates to a ballistic protective material, in particular for armoring, which may comprise a ballistic multilayer material of the aforementioned type to achieve the aforementioned advantages, in particular to a horrin ⁇ dest essential portion made of this ballistic Mehr ⁇ harshmaterial and advantageously as a blanket, curtain or Plane can be made up.
• the ballistic multilayer material may have a certain rigidity, in particular as hot pressed, preferably at least 200 ° C and at least 15 bar, advantageously at 250 ° - 300 ° C and 100 - 200 bar H Formulaverpresster, rigid composite may be formed.
