“…For other relatively simple performance tests, Yeh et al 53 found that the maximum pull-out force of the sheer thickening fluid (STF)/ Kevlar composite was 3.17 times as large as that of Kevlar, and the physical properties of the fabric were significantly improved. Besides the enhancement of energy absorption and strength, Liu et al 54 studied a new type of carbon nanotube (CNT)/STF/Kevlar-based wearable electronic material, having excellent protection and sensing properties.…”

In studies of ballistic impact, the materials used in body armor must have high hardness, light weight, fatigue resistance, corrosion resistance, and other high performance characteristics. Aramid fibers are widely used in anti-ballistic materials. To facilitate the further development of aramid materials, this study reviews aramid research in recent years and analyzes the main factors affecting, and new methods for optimizing, anti-ballistic performance, with the emphasis on bulletproof fabrics. This review provides suggestions for future research and use of aramid materials for anti-ballistic performance.

“…When a sudden force is applied, viscosity increases dramatically but recovers to its initial state immediately when applied stress is relieved . STF-based wearable electronic textiles have been fabricated for body armors with variable flexibility and conductivity depending on the applied deformation. , In addition, STF-processed Kevlar fabrics (STKF) exhibit an EM interference shielding effect as high as 27 dB …”

Patient-friendly medical diagnostics and treatments have been receiving a great deal of interest due to their rapid and cost-effective health care applications with minimized risk of infection, which has the potential to replace conventional hospital-based medical procedures. In particular, the integration of recently developed materials into health care devices allows the rapid development of point-of-care (POC) sensing platforms and implantable devices with special functionalities. In this review, the recent advances in biosensors for patient-friendly diagnosis and implantable devices for patient-friendly treatment are discussed. Comprehensive analysis of portable and wearable biosensing platforms for patient-friendly health monitoring and disease diagnosis is provided, including topics such as materials selection, device structure and integration, and biomarker detection strategies. Moreover, specific challenges related to each biological fluid for wearable biosensor-based POC applications are presented. Also, advances in implantable devices, including recent materials development and wireless communication strategies, are discussed. Furthermore, various patient-friendly surgical and treatment approaches are reviewed, such as minimally invasive insertion and mounting, in vivo electrical and optical modulations, and post-operation health monitoring. Finally, the challenges and future perspectives toward the development of the patient-friendly diagnosis and treatment are provided.

“…Additionally, the STF allowed the reduction of reinforcement layers from 32 to 19, while maintaining the same ballistic properties of the composite [ 64 ] ( Table 4 ). The laminates made by Liu additionally reinforced with an STF based on silica and CNTs had more than 50% higher puncture resistance, absorbed 65% more energy, and thus, could withstand more impact force [ 65 ]. Dixit showed that STF impregnation increases energy absorption of the reinforced fabric by 10% more compared to pure Kevlar fabric.…”

Hybrid Polymer Composites Used in the Arms Industry: A Review

Polymer fiber composites are increasingly being used in many industries, including the defense industry. However, for protective applications, in addition to high specific strength and stiffness, polymer composites are also required to have a high energy absorption capacity. To improve the performance of fiber-reinforced composites, many researchers have modified them using multiple methods, such as the introduction of nanofillers into the polymer matrix, the modification of fibers with nanofillers, the impregnation of fabrics using a shear thickening fluid (STF) or a shear thickening gel (STG), or a combination of these techniques. In addition, the physical structures of composites have been modified through reinforcement hybridization; the appropriate design of roving, weave, and cross-orientation of fabric layers; and the development of 3D structures. This review focuses on the effects of modifying composites on their impact energy absorption capacity and other mechanical properties. It highlights the technologies used and their effectiveness for the three main fiber types: glass, carbon, and aramid. In addition, basic design considerations related to fabric selection and orientation are indicated. Evaluation of the literature data showed that the highest energy absorption capacities are obtained by using an STF or STG and an appropriate fiber reinforcement structure, while modifications using nanomaterials allow other strength parameters to be improved, such as flexural strength, tensile strength, or shear strength.
