Abstract

High protection performance and intelligence are gradually becoming indispensable key factors with the ever-improving personal protective equipment. However, protective material that can not only resist but also percept full type of impacts is an urgent need due to complex combat scenarios. This work reports an intelligent leather/shear stiffening gel (SSG)/Kevlar-shear thickening fluid (STF)/non-woven fabric (LSKSN) composite, which exhibits superior and comprehensive impact resistance performance in needle puncture, knife puncture, ballistic impact, and blunt impact. Especially, the LSKSN composite not only improves the puncture resistance performance by 71% but also still maintains a large resistance after being punctured. Moreover, the LSKSN composite possesses a high limit penetrated velocity of 159 m s⁻¹ and can dissipate a high impact energy of 24.6 J, causing the bulletproof to be improved by 22%. Due to the excellent force-buffering performance and rate-dependent energy dissipation characteristics in wide-impact energy, the maximum energy dissipation rate of the LSKSN composite reaches 95%. Simultaneously, the further developed electronic LSKSN (E-LSKSN) composite shows outstanding perceptual capability, which is sensitive to various impacts and can accurately identify the impact types through different resistance changes (10–8000%) and response times (0.1–100 ms). Finally, based on the bending sensing and impact sensing properties of the E-LSKSN composite, a wireless signal transmission system is constructed to monitor the safety and movement status of the human body in real-time, which demonstrates this LSKSN composite possesses high potential in the next generation of intelligent protective equipment.

智能皮革安全防护与冲击感知同步增强

随着个人防护装备的不断完善，高防护性能和智能化逐渐成为不可或缺的关键因素。然而，由于复杂的作战场景，迫切需要既能抵抗又能感知全类型冲击的防护材料。本研究报道了一种智能皮革/剪切强化凝胶(SSG)/凯夫拉剪切增稠液(STF)/无纺布（LSKSN）复合材料，该复合材料在针刺、刀刺、弹道冲击和钝性冲击中表现出优异的综合抗冲击性能。特别是LSKSN复合材料不仅能提高71%的抗穿刺性能，而且在被刺穿后仍能保持较大的阻力。此外，LSKSN复合材料具有159 m s−1的最高极限穿深速度，并能消耗24.6 J的高冲击能量，使防弹性能提高22%。由于优异的力缓冲性能和在大冲击能量下随速率变化的能量耗散特性，LSKSN复合材料的最大能量耗散率可达95%。同时，进一步开发的电子LSKSN （E-LSKSN）复合材料表现出出色的感知能力，对各种冲击敏感，可以通过不同的电阻变化（10-8000%）和响应时间（0.1-100 ms）准确识别冲击类型。最后，基于E-LSKSN复合材料的弯曲传感和冲击传感特性，构建了无线信号传输系统，实时监测人体的安全和运动状态，证明了该复合材料在下一代智能防护装备中具有很高的潜力。图形抽象

期刊介绍： Advanced Composites and Hybrid Materials is a leading international journal that promotes interdisciplinary collaboration among materials scientists, engineers, chemists, biologists, and physicists working on composites, including nanocomposites. Our aim is to facilitate rapid scientific communication in this field. The journal publishes high-quality research on various aspects of composite materials, including materials design, surface and interface science/engineering, manufacturing, structure control, property design, device fabrication, and other applications. We also welcome simulation and modeling studies that are relevant to composites. Additionally, papers focusing on the relationship between fillers and the matrix are of particular interest. Our scope includes polymer, metal, and ceramic matrices, with a special emphasis on reviews and meta-analyses related to materials selection. We cover a wide range of topics, including transport properties, strategies for controlling interfaces and composition distribution, bottom-up assembly of nanocomposites, highly porous and high-density composites, electronic structure design, materials synergisms, and thermoelectric materials. Advanced Composites and Hybrid Materials follows a rigorous single-blind peer-review process to ensure the quality and integrity of the published work.
