Definitions
- the present invention relates to a high hardness steel for armor, over-armor and overprotection flap, usable in the form of sheet metal and / or parts and having high ballistic performance.
- hot rolling is carried out at a temperature between 1150 and 1250 ° C with a degree of wrought greater than 2.
- the quenching in press which avoids significant deformation Aunt of the sheet, is carried out after heating to a temperature between 800 and 960 ° C.
- the overprotection flap allows acceptable visibility and provides effective ballistic protection.
- the steel according to the invention has better properties in elasticity and in hardness than 28 NCD6 steel with a comparable impact resistance.
- the steel according to the invention can be cut by plasma, flame cutting or laser process, with precautions adapted to the different sheet thicknesses.
- the latter In order to optimize the ballistic performance of the sheet subjected to the impacts of projectiles, the latter, after rolling, is pierced with orifices.
- the holes have, for example, a diameter between 3 and 15 mm.
- the sheet pierced with orifices is then quenched, then subjected to tempering under the conditions described above.
- the surface mass of the perforated sheet is reduced in the ratio of the overall surface of the orifices to the total surface of the sheet before drilling, the sheet being able to have from 30 to 60% reduction in weight, for the same ballistic protection efficiency.
- the holes improve the resistance to cracking during impacts.
- the shielding is formed from a massive sheet 1 (Fig. 1) according to the invention, covered on one of its faces or on its two faces with a material synthetic 2 such as for example an elastomer which can be reinforced, by mixing it with a synthetic fiber.
- a material synthetic 2 such as for example an elastomer which can be reinforced
- the invention finds its application in particular of armor plating, placed in front of armorings of already existing structure, armor plating which make it possible to smash the projectile and therefore to reduce its perforating power.
- the invention also finds its application in a ballistic overprotection shutter for windows or windshields of light armored vehicles.
- the shell 10 has openings and in particular at the front an opening 20 provided with glazing 30 that is slightly armored and allowing the driver to have good visibility and thus be able to steer the vehicle.
- the vehicle is equipped with folding flaps 40 formed by a shield 50 of very high hardness steel according to the invention.
- the shield 50 is pierced with a multitude of small orifices 60 regularly distributed and representing 30 to 60% of vacuum relative to the surface of said plate.
- the orifices 60 have a diameter less than the smallest caliber which the windshield and the shutter 40 alone do not protect with the glazing 30 an empty space. This arrangement makes it possible to obtain over-protection of the windows or windshield of the vehicle, while ensuring visibility thanks to the large number of small orifices 60.
