Abstract

Industry and market of ballistic protection materials and systems are characterized by a dynamic and competing succession of inventions for projectiles and protective systems. The requirements for the ballistic panels are many and complex, varying depending on the threat type, the required mobility in the tactical theater, and protection level. The safety degree, the price, and the dynamics of research in the field are also taken into account. This chapter underlines the necessity of testing ballistic protection panels made of LFT SB1 plus (multidirectional fiber fabrics, supplied by Teijin) against a certain threat in order to assess their resistance to this specific threat and the investigation of failure mechanisms in order to improve their behavior at ballistic impact. The models for ballistic impact are useful when they are particularly formulated for resembling the actual system projectile, target, and can be validated through laboratory experiments. Tests made on panels made of LFT SB1plus, according to NIJ Standard-0101.06-2008 gave good results for the panels made of 12 layers of this fabric, and the backface signature (BFS) was measured. The BFS upper tolerance limit of 24,441 mm recommends this system for protection level IIA, according to the abovementioned standard.

芳纶装甲板的弹道试验

弹道防护材料和系统的工业和市场的特点是弹丸和防护系统发明的动态和竞争继承。对弹道防护板的要求是许多和复杂的，根据威胁类型、战术战区所需的机动性和防护水平而变化。安全程度、价格和该领域的研究动态也被考虑在内。本章强调了测试由LFT SB1 plus(由帝人提供的多向纤维织物)制成的弹道防护板的必要性，以评估其对这种特定威胁的抵抗力，并研究失效机制，以改善其在弹道冲击下的行为。当弹道冲击模型与实际系统弹丸、目标相类似，并能通过实验室实验加以验证时，这些模型是有用的。根据NIJ标准-0101.06-2008，对LFT SB1plus制成的面板进行了测试，结果表明，由12层这种织物制成的面板效果良好，并测量了背面签名(BFS)。根据上述标准，BFS的上限公差为24,441 mm，建议该系统的防护等级为IIA。

期刊介绍： Journal of Ballistics is an academic journal published by China Association for Science and Technology (CAST) and sponsored by China Society of Military Science and Industry (CSMI) at home and abroad. Founded in 1989, it is the only academic journal in the field of ballistics in China. The purpose of the journal is to exchange the latest achievements and related applications in the field of ballistics, introduce the new technology of ballistic testing, broaden the channels of information exchange, exchange academic ideas, promote the development of ballistics and military-industrial technology, and work hard to achieve the modernisation of national defence. Journal of Ballistics is a Scopus-listed journal, Chinese core journal, Chinese science and technology core journal and CSCD core journal. The Honorary Editor-in-Chief is Academician Li Hongzhi, an academician of the Chinese Academy of Engineering, and the Editor-in-Chief, Professor Wang Zhongyuan, is a Distinguished Professor of the Yangtze River Scholars Award Scheme. Journal of Ballistics mainly publishes the latest research results in the fields of ballistics, including internal ballistics, intermediate ballistics, external ballistics, underwater ballistics, terminal ballistics, trauma ballistics, experimental ballistics, launch dynamics, aerodynamics, flight mechanics, navigation and guidance, ballistic design and control, ballistic system synthesis and analysis, ballistic test technology, ballistic and archery in general and the laws of motion of flying objects. Academic papers on the latest research results on the laws of motion of flying objects.
