Description
技术领域 本实用新型涉及一种防弹钢板，尤其涉及一种可提高防弹车防弹性能的钢板。 Technical Field The utility model relates to a bulletproof steel plate, in particular to a steel plate that can improve the bulletproof performance of a bulletproof vehicle.
背景技术 防弹车是新发展起来的一种专用车，防弹车系列众多，不同的使用方面有不同的具体要求，而防弹则是共同的基本要求，而如何提高防弹车的防弹性能是该领域的核心研究课题，目前，提高防弹车的防弹性能一般通过两个途径：一是通过增加防弹材料的厚度，可以防止子弹侵彻防弹车，但一味的提高防弹材料的厚度，必然会增加汽车的质量，从而降低了汽车的动力性，使防弹车不能快速驶离危险现场，增加了车内人员的生命和财产的危险性；二是提高防弹材料的性能，但是提高防弹材料的强度同时，也增加了防弹材料的脆性，不利于防弹材料吸收子弹的动能，而且通过提高防弹材料的性能来提升防弹车的防弹性能也是很困难的。 Background Art Bulletproof vehicles are a newly developed special-purpose vehicle. There are many series of bulletproof vehicles, and different uses have different specific requirements, but bulletproof is a common basic requirement, and how to improve the bulletproof performance of bulletproof vehicles is a key issue in this field. The core research topic. At present, there are generally two ways to improve the bulletproof performance of bulletproof vehicles: one is to prevent bullets from penetrating bulletproof vehicles by increasing the thickness of bulletproof materials, but blindly increasing the thickness of bulletproof materials will inevitably increase the quality of the vehicle , thereby reducing the power of the car, so that the bulletproof car cannot quickly drive away from the dangerous scene, which increases the danger to the life and property of the people in the car; the second is to improve the performance of the bulletproof material, but at the same time increasing the strength of the bulletproof material also increases The brittleness of the bulletproof material is not conducive to the bulletproof material absorbing the kinetic energy of the bullet, and it is also very difficult to improve the bulletproof performance of the bulletproof vehicle by improving the performance of the bulletproof material.
发明内容 本实用新型的目的在于提供一种不仅克服以增加防弹材料的厚度和提高防弹材料的性能带来的弊端，采取改变防弹材料的结构，达到提高防弹性能的目的，减少人力、财力的投入，而且结构简单，便于制造，制造成本低，效果好的防弹钢板。 SUMMARY OF THE INVENTION The purpose of this utility model is to provide a method that not only overcomes the disadvantages caused by increasing the thickness of the bulletproof material and improving the performance of the bulletproof material, but also improves the bulletproof performance by changing the structure of the bulletproof material, and reduces the input of manpower and financial resources. , and the structure is simple, easy to manufacture, low manufacturing cost, good bulletproof steel plate.

The inner plate is a flat steel plate, and two plates whose axes are parallel to the inner plate are set between the inner plate and the outer plate, that is, the sandwich plate I and the sandwich plate II, and the sandwich plate I and the sandwich plate II Both are steel plates with a wavy cross-section, in which the sandwich plate I is close to the inner plate, and the sandwich plate II is close to the outer plate; the inner plate and the sandwich plate I are connected together through the upper and lower external parts between them , that is, the upper and lower ends between the inner plate and the sandwich plate Ⅰ are respectively equipped with outer connecting parts, the outer connecting parts are bent plates, one end of each outer connecting Welded together; the above-mentioned outer plate and sandwich plate II are connected together by the upper and lower disc springs between them, that is, the upper and lower ends of the outer plate and sandwich plate II are respectively provided with disc springs, each One end of the disc spring in the axial direction is welded to the outer plate, and the other end in the axial direction is welded to the sandwich plate II; between the inner plate and the sandwich plate I, between the sandwich plate I and the sandwich plate II, and between the sandwich plate There are fillers between II and the outer layer, which are composite fiber materials with bulletproof capability, such as: WB-212 type PEUD bulletproof non-woven fabric (area density: 150±8g/㎡, thickness: 0.16mm) Or FT-102 type aramid UD bulletproof non-woven fabric (area density: 230～240g/㎡, thickness: 0.2 mm) or TYZWB-211 type bulletproof non-weft fabric (area density: 305±15g/㎡, thickness: 0.34± 0.02 mm).
其中优选的：外层板的厚度为1.8～2.2mm，更优选的：外层板的厚度为2mm。 Among them, preferably: the thickness of the outer layer plate is 1.8-2.2 mm, and more preferably: the thickness of the outer layer plate is 2 mm.
其中优选的：里层板的厚度为0.6～1.0mm，更优选的：里层板的厚度为0.8mm。 Among them, preferably: the thickness of the inner layer board is 0.6-1.0 mm, and more preferably: the thickness of the inner layer board is 0.8 mm.

It plays a very good protective role. The slope of the sandwich plate has an included angle with the horizontal plane. When the bullet penetrates the sandwich plate vertically, the penetration force is decomposed into a tangential force along the slope and a normal force perpendicular to the slope. In addition, two There is friction in the relative displacement between the interlayer plates with inclined surfaces, and the kinetic energy of the bullet is attenuated under the action of them together, so that the speed of the bullet drops rapidly, and the penetrating ability of the bullet is weakened; The ability of composite fiber materials, they can also play a role in attenuating the kinetic energy of the bullet, reducing the speed of the bullet and weakening the penetrating ability of the bullet.
