Definitions
- the invention relates to an armor, in particular for Security vehicles, with which the energy impacted projectiles absorbed and their penetration is prevented.
- the steel is predominantly referred to as Forging, rolling or casting in hard shredding and in mining and road construction for fangs, coats for rolls and cone crushers, blow bars for bouncing cups, etc. used.
- This steel is prone to severe deformation, i. at strong degrees of deformation, cracking and is for the Use as armor not yet known.
- the invention is based on the object, an armor for safety vehicles to develop which of Contour of the vehicle body is completely adaptable, without costly changes of the body in the Vehicle can be installed and at relatively low Weight ensures good fire safety.
- the ratio of carbon and manganese content of the Steel is about 1:10.
- These properties will be for example, of the steel X120Mn12 (number 1.340), in which the resulting from the hot forming edge-decarburized layer mechanically, preferably by Grind with cooling (maximum temperature 250 ° C) away has been.
- the ballistic behavior of the armor can also be the solidification of the Surface structure of the basic structure when sanding or one of the mechanical processing downstream Processing stage (e.g., sandblasting, bombardment with Stahlkugen shot blasting, diamond flattening, calibrating or rolls with low delivery).
- sandblasting bombardment with Stahlkugen shot blasting, diamond flattening, calibrating or rolls with low delivery.
- the element can either form the bodywork or these strengthen and be formed one or more layers, wherein the individual layers at least partially with each other bonded (e.g., welded) and formed together.
- the Thickness of the element preferably starts from 0.5 mm. In the Machining is done on both sides of a layer in of the order of magnitude up to 0.25 mm, so that the edge-decarburized structure is removed down to the basic structure.
- Another unpredictable positive effect is the better cold workability and thus a good three-dimensional formability after removing the Edge decarburized layer record. It's essential Higher degrees of deformation possible, with a crack in the Surface, especially at small bending radii, avoided becomes. As a result, the armor is almost completely in the Type of a three-dimensional molded part to the contour of the Vehicle body adaptable because even small radii malleable are.
- the unpredictable outstanding ballistic Properties allow the production of armor with only small sheet thickness, which is costly Changes to the bodywork and interior decoration Installation of armor in the vehicle to a minimum reduce or even avoid completely.
- Edge decarburized layer thus has a positive effect on the ballistic behavior as well as on cold workability out. Deformed when hitting a bullet (projectile) the armor without cracking at this position and increasingly solidified by the occurring strong curing, so that the energy of the projectile (Projectile) is completely absorbed.
- Fig. 1 shows in a schematic way the cross section of the outer part of a vehicle door whose inner and outer skin 2 consists entirely of a hot-rolled wear-resistant austenitic manganese steel X120Mn12 whose thickness is for example in the range of about 2.5 mm to 3.5 mm.
- the chemical composition (analysis values in percent) is shown in the following overview: C Si Mn P S Cr 1.10 0.25 11.5 Max. Max. Max. 1.30 0.50 13.5 0.10 0,040 o, 5
- the hardness is 210 to 240 HBW (Brinell hardness).
- carbide-forming elements e.g., Crom -Cr-
- the proportion of carbide-forming elements should be in the sum below 5% and there should be no be present line-shaped precipitates.
- This armor does not only hold surface shock loads due to a vehicle crash, but also punctate Impact loads due to bombardment of the fire class FB3 and FB4 to DIN EN 1522 dependably, both in levels as well as in curved door areas.
- This kind of Armor can be realized very easily, from which also a high reliability of the bullet defense results. Not shown are several layers of these steels, the partially welded together and together are transformed. Your total thickness can turn for example, be about 2.5 to 3.5 mm. Of course, larger sheet thicknesses of Eizelblechen or multilayer sheets possible.
- FIG. 2 another variant is shown in the the body panel 4 of about 1 mm thickness by a internal armor 2 is reinforced. Even though shown in full detail, this can Reinforcement of course on particularly vulnerable Restrict areas that are also heavily shaped can.
- FIG. 3 Another type of reinforcement is shown in FIG. 3.
- FIG. 4 A combination in which the body panel 4 by a Covered armor 2 backed off with fiber composite material Reinforced multiphase steel is shown in FIG. 4.
