Definitions

  • the invention relates to armor against shelling by high Velocity hitting particles, especially the projectiles of hand and Handguns.
  • Such armor is primarily used as a personal protective vest Armor for land, air and water vehicles needed to do this To protect operating personnel. This affects everyone in passenger cars Inmates.
  • Any rigid armor for example consisting of a relatively thick Steel sheet etc. must match the shape of the receiving cavity or Be adapted to what is just in the armor of vehicles in small quantities represent a considerable amount of work.
  • the deflection or deformation of the armor may be transverse to the plane armor only reached a defined value when fired at because especially in the passenger car the people to be protected in a relative sit a short distance behind the armor.
  • armor plates are made of flexible material such as fabrics tear-resistant materials, for example aramid fibers, known in principle, the z. B. can intercept a rifle projectile. The resulting deflection of the However, the fabric is relatively large. At a z. B. 1m x 1m large area of a such aramid fabric in which the attachment is made only at the edges Should, when deflected in the middle, the deflection can be transverse to the plane of the fabric be quite 30 cm, so that protection for very close behind the fabric sedentary people can not be guaranteed. If you want to avoid this up to 100 or more fabric layers are required, which requires a lot of space and heavy weight required.
  • the individual plates are there riveted to a carrier fabric and moreover by positive Interlocking of the individual plates through projections and recesses, which have an undercut, prevented from being pulled apart and form a joint so large that a projectile can penetrate through it can.
  • this requires complex assembly on the one hand and on the other hand can only be caused by careless handling, for example excessive bending of the Armor, disengagement of the plates is what armor partially unusable.
  • the interception mat usually consists of a textile-like material, in particular one or more layers of fabrics made of highly tear-resistant fibers, and is therefore flexible and flexible.
  • the panels arranged side by side consist in particular of a light, high-strength material.
  • Ceramic has proven to be suitable for this purpose, for example metal oxides such as aluminum oxide, for example Al 2 O 3 .
  • the hard panels are particularly flexible, pliable Supporting fabric side by side and without spacing, i.e. with as few joints as possible, especially touching directly next to each other, attached.
  • the fastening can be by gluing, sewing or any other known method respectively. It must be ensured that the plates are not so far can separate from each other to the passage of a projectile at this point to enable or even to facilitate.
  • the support fabric in the plane of the fabric should be free of stretch, e.g. B. a Have aramid fabric.
  • a bending of the plate layer is only possible in one direction, since one such a bend, in which the supporting fabric is on the outside of the bend would lie, the narrow sides of the plates lying perpendicular to the main plane would be pressed against each other, and because of the lack of elasticity of the backing fabric can only bend if the panels are destroyed would.
  • the edges of the panels are neither beveled, still rounded, which would also make production more expensive and damage by breaking off these then weakened edge areas would ease.
  • the plates on the fire side are also included a top layer firmly connected, preferably glued again, in particular fully glued.
  • This top layer is in contrast to the base fabric from a stretchable elastic in both directions in the main plane spring back the initial state, material, for example a layer made of natural rubber or synthetic rubber, with a thickness of 0.5 - 3, especially 1 - 2 mm thick.
  • An expansion behavior is preferred, whose resistance increases with increasing elongation, and in particular the tensile strength is very high and the sensitivity to Partitions, for example by the edges of the Plates, is low.
  • the plates have a maximum thickness of 7 mm, preferably 5 mm, preferably 3 mm, do not exceed this results on the open side of the V-joints a joint width of less than 2 mm, especially only of fractions of mm, what a penetration of a projectile without strong braking and energy destruction is not enough.
  • the V-joints point to theirs The back is still 0 in width, as the panels are still in there Touch each other.
  • the plates have a maximum size in the main plane, the at square plates a maximum of 30 mm edge length, preferably a maximum of 20 mm edge length, preferably corresponds to a maximum of 15 mm edge length.
  • Other Poligon forms that are in particular more than four corners especially designed as uniform poligons, the diagonals of which should correspond to the diagonals of the aforementioned squares as the maximum value. Triangular shapes are because of the acute corner angles and the easy break of these corners less suitable.
  • a minimum thickness of the panels should also be adhered to adequate support of the narrow sides of the plates against one another To achieve a bending test concave to the direction of fire, which is particularly the case with Bombardment itself.
  • the minimum thickness of the panels should be 1.0 mm, in particular 1.5 mm, in particular 2.5 mm.
  • the one behind the layer of hard plates in the direction of fire Interception mat consists in particular of several layers of a bullet aggravating fabric, which by quilting seams or only quilting points in fixed distances connected to each other, in particular sewn or are glued. It is possible to arrange several mats in a row. Basically, the dimensioning, i.e. the choice of material depending on Thickness of the hard plates as well as number of interception mats, thickness or Number of layers of the individual interception mats etc. in relation to the expected Shelling be set.
  • the material for the interception mats which are made in particular several layers of intercepting fabrics are aramid fibers, whereby especially the fibers from a large number of essentially parallel, filaments that are not twisted.
  • the interception mats made of aramid fibers are included completely enclosed by a moisture-proof or waterproof film.
  • the hard plates are also from the film, in particular Ceramic plates included.
  • the or the supporting fabric for the hard plates can with one of the layers of Interception mat be identical.
  • the supporting fabric of the panels with the interception mat be connected, at least along the edges of the armor, preferably however on the surface of the armor.
  • the moisture-proof film can also function as a supporting fabric for hard plates, especially ceramic plates.
  • the armor can be attached to the load in different ways Component, for example the outer skin of a vehicle made of sheet metal are attached, only to maintain the tightness of the Is to be observed and in addition to sufficient strength of the Connection so that the armor does not detach itself from the load-bearing component may loosen.
  • Component for example the outer skin of a vehicle made of sheet metal are attached, only to maintain the tightness of the Is to be observed and in addition to sufficient strength of the Connection so that the armor does not detach itself from the load-bearing component may loosen.
  • Velcro which is in the form of Velcro straps can be present.
  • Velcro fasteners these in defined areas and maximum distances along the plane to arrange the armor between the armor and the load-bearing component, for example between the film and the supporting structure, if the film is the represents the outermost layer of armor.
  • Fig. 1 shows in the bombardment direction 10 continuously from right to left - next to the approaching projectile 1 - the receiving component, i.e. the supporting part 11, which can be the outer panel of a motor vehicle, for example.
  • the receiving component i.e. the supporting part 11, which can be the outer panel of a motor vehicle, for example.
  • the outermost Layer of armor consists of a moisture-proof film 9, which is around the entire inner layers of the armor extends around and in Fig. 1 is open on the underside for introducing the inner layers of the Armor.
  • the film 9 On this open lower side is the film 9, so its left and right surface 9a or 9b, preferably together with the other layers the armor, tightly clamped between two clamping plates 8, the can be pressed against one another by clamping screws 7 or other aids, and also attached to the support member 11, for. B. screwed can.
  • the film 9 is at the upper edge and the side edges, not shown closed.
  • the layer adjoins the right layer of the film 9b from ceramic plates 3 arranged side by side in a vertical plane. These are fixed in their relative position to each other by being on both sides with a Support fabric are glued, which is over the top of this layer extends around and thus a left supporting fabric 13a and a right Forms support fabric 13b for the layer of ceramic plates 3.
  • the ceramic plates 3 are arranged with very little joints to each other, and the supporting fabric 13 is only very little stretchable in the longitudinal direction of the fabric.
  • the ceramic plates 3 are bonded to the supporting fabrics 13a / 13b either all over, as on the left side of the top ceramic plate 3 shown, or in the form of individual dots or stripes, such as the one below lying ceramic plates 3 can be seen.
  • the bonds can on the opposite sides of the ceramic plates 3 in the same places be arranged as shown in the bottom ceramic plate 3, or straight offset to each other, as shown in the middle ceramic plate 3, whereby the Flexibility of the entire layer with the ceramic plates 3 is improved.
  • interception mats 4 In the firing direction 10 behind this layer are two interception mats 4 arranged, each consisting of a larger number of each other regular quilting 5 connected layers of intercepting fabrics 14 exist.
  • the two interception mats 4 are concrete by folding a single one Interception mat at the top edge and double-layer hanging down Interception mat 4 formed. Preferably takes place at the top or in the top Area a connection of these interception mats 4 especially with the layer of Ceramic plates 3 and / or the surrounding film 9 and / or the supporting part 11. This can be facilitated by the fact that, in contrast to the illustration in FIG. 1 the screwing and jamming shown in Fig. 1 at the bottom is present at the upper edge and also serves as a suspension there can.
  • Fig. 2 shows the situation in an enlarged detail when the bombardment has taken place
  • the bombardment energy was so great that the projectile 1 hit Has broken through ceramic plate 3, which is thereby divided into fragments 3 ' has been.
  • the supporting fabric 13a, 13b is also penetrated, even if it is consists of highly tear-resistant fibers, which does not necessarily have to be the case. The same applies to the right layer 9b of the surrounding film.
  • the projectile In addition to the deformation, the projectile also becomes straight Trajectory deflected, and strikes the interception mat at an angle, what their Penetration additionally difficult.
  • the projectile is usually used instead when striking the Ceramic plate divided into several fragments, and these in not exactly the distracted in the same direction, which is also due to the restraint by the Interception mats relieved.
  • the shell peels when it penetrates the ceramic plate from its core, so that again either separate parts or a single part with greatly enlarged, irregular Front surface, after the ceramic plate has broken through, is present.
  • a typical size of the ceramic plates is 20 x 20 mm or 10 x 10 mm, in any case not larger than 30 x 30 mm, and this with a plate thickness of less than 5 mm, preferably 2-4 mm.
  • the interception mat 4 is deformed by the impact of the Projectile 1 'is deflected in the weft direction 10, that is to the left in FIG. 2, however only limited.
  • Fig. 2 shows in particular that the ceramic plates 3 at least opposite Support fabric 13a, in particular with respect to both support fabrics, over the entire surface are glued. This also prevents fragments from detaching penetrated plates 3 '.
  • the mat 4 is quilted preferably not as point stitching, but in the form of intersecting, especially at right angles, quilting seams that are 20-40 apart, in particular at a distance of 30 cm from each other.
