摘要

在这项研究中,采用了一种新的战略来开发先进的轻型弹道装甲。这种新一代的弹道防护被称为“混合型”,在某些Kevlar层中浸渍了一种高性能的绿色无双酚a热固性树脂,即香草醛基苯并恶嗪(Va BZ)。热固性聚合物的作用是减缓和阻止抛射物。此外,减少了具有最小Kevlar层数的背面特征(BFS)。事实上,这种基质不仅具有该领域最高的交联密度之一,而且还具有优异的机械和热性能。所采用的实验方法包括以5为增量逐渐改变浸渍的Kevlar层的数量。最终目标是将Kevlar层的数量从26层(目前正在使用)减少到20层,同时确保BFS小于44毫米(根据国家司法研究所标准NIJ-0101.06的要求)。事实上,所采用的策略允许显著减少BFS。例如,由20层Kevlar层制成的盔甲(其中10层被Va-BZ浸渍)显示出36.54mm的最小BFS值。因此,通过引入Va-BZ树脂,无孔Kevlar织物获得了足够的刚度,以在最小变形的情况下承受冲击。总的来说,这些新开发的盔甲提供了最好的BFS来保护人体的重要部位。

New strategy for the development of lightweight ballistic armors with limited backface signature
In this study, a new strategy is adopted for the development of advanced, and lightweight ballistic armor. This new generation of ballistic protections is referred to as “hybrid”, in which certain layers of Kevlar have been impregnated with a high-performance green and bisphenol-A free thermosetting resin, namely the vanillin-based benzoxazine (Va-BZ). The role of thermosetting polymer is to slow down and stop the projectile. In addition, the backface signature (BFS) with a minimum number of Kevlar layers is reduced. Indeed, this kind of matrix not only possesses one of the highest crosslinking densities in the field, but also offers excellent mechanical and thermal properties. The adopted experimental approach consists in gradually changing, in increments of 5, the number of impregnated Kevlar layers. The ultimate goal is to reduce the number of Kevlar layers from 26 (currently in use) to 20 while ensuring a BFS of less than 44 mm (as per the requirement of the National Institute of Justice standard NIJ-0101.06). Indeed, the adopted strategy allowed significant reduction in the BFS. For instance, armors made of 20 layers of Kevlar layers in which 10 layers were impregnated by the Va-BZ displayed the minimal BFS value of 36.54 mm. Hence, by introducing the Va-BZ resin, the non-perforated Kevlar fabrics gained enough rigidity to sustain the impact with minimal deformation. Overall, these newly developed armors offer the best BFS possible to protect vital human body parts.

期刊介绍: Health Services Management Research (HSMR) is an authoritative international peer-reviewed journal which publishes theoretically and empirically rigorous research on questions of enduring interest to health-care organizations and systems throughout the world. Examining the real issues confronting health services management, it provides an independent view and cutting edge evidence-based research to guide policy-making and management decision-making. HSMR aims to be a forum serving an international community of academics and researchers on the one hand and healthcare managers, executives, policymakers and clinicians and all health professionals on the other. HSMR wants to make a substantial contribution to both research and managerial practice, with particular emphasis placed on publishing studies which offer actionable findings and on promoting knowledge mobilisation toward theoretical advances. All papers are expected to be of interest and relevance to an international audience. HSMR aims at enhance communication between academics and practitioners concerned with developing, implementing, and analysing health management issues, reforms and innovations primarily in European health systems and in all countries with developed health systems. Papers can report research undertaken in a single country, but they need to locate and explain their findings in an international context, and in international literature.
