“…In order to calculate the energy absorption of the neat fabric, PS/fabric and TS/fabric composites, the equation Eabs=∫Fds was applied. 36 Figure 12(a) and (b) displays the peak force and the energy absorption at yarn pull-out speeds of 10 and 200 mm/min, respectively. For the high pull-out speed, the energy absorption of TS60/fabric composite obtained was 380 and 108% more than the neat fabric and PS/fabric composite, respectively.…”

“…As seen in Figure 12(a) and (b), the rising tendency of energy absorption is almost similar to the peak force of yarn pull-out, specifically at the high pull-out speed, which is in agreement with the result in literature. 36 Figure 12.The influence of impregnating neat fabric with the PSTF and TSTF: (a) 10 mm/min pull-out speed and (b) 200 mm/min yarn pull-out speed.

“…Tan et al reported that energy absorption and the peak pull-out force of reinforced fabric by STF is more significant than the one in the neat fabric because the viscosity of STF will hinder the yarn from slipping. 36 Several experiments have been performed to study the yarn pull-out behavior of fabrics. 37,38 However, it seems that yarn pull-out for the 3D E-glass fabric is not well understood.…”
In this study, a new low-velocity shear impact test was introduced to carefully investigate the resistance of 3D E-glass fiber reinforced polymer composites with shear thickening fluid matrix. The shear thickening fluids were prepared by dispersing silica nano-particles in polyethylene glycol. Pure shear thickening fluid was modified by treating the silica surface with (3-Aminopropyl) triethoxysilane. Despite the low-velocity shear impact test, various experimental tests such as yarn pull-out, quasi-static puncture, flexibility and thickness tests were carried out to study the mechanical behavior of the composites. Results revealed the treated shear thickening fluid up to 60 wt% improves the performance of the impregnated samples against the yarn pull-out and puncture tests by 353% and 45%, respectively, and their shear impact resistance by 130% compared to the neat cases without noticeably affecting the fabric flexibility.

“…Moreover, reinforced STF also has a significant influence on the ballistic limit and energy absorption of Kevlar fabrics. And the increased amplitude of energy absorption is almost 20% more than the pure STF/Kevlar load case [145].…”
Section: Application Of Textile Composites Modified With Graphene Strmentioning
Graphene is a new, advanced material with many possible applications in basic and clinical medicine, electronics and automation. Graphene compounds can be successfully used as an integral part of drug delivery systems, in the construction of transistors, polar processors, touch screens, solar cells and in the production of materials for the manufacture of personal protective equipment, i.e. products and equipment intended to protect the health and life of users. The literature review presented in this paper concerns physical and mechanical properties of composites containing graphene or its structure as well as methods of obtaining polymer, metallic and ceramic composites doped with graphene structures. Data analysis of the potential use of graphene and its composites in personal protective equipment such as monitoring sensors, clothing and security equipment such as ballistic armor, helmets and protective clothing were also reviewed and summarized.
“…These properties in combination make STF-impregnated fabrics a high-potential focus for next-generation body armour and the subject of extensive research on body armour for ballistic performance (Cao et al, 2017;Fahool and Sabet, 2016;Laha and Majumdar, 2016;Lee et al, 2003Lee et al, , 2013Majumdar et al, 2013;Park et al, 2013Park et al, , 2014Petel et al, 2015;Wetzel, 2004) and stab resistance (Feng et al, 2014;Gong et al, 2014;Gürgen & Kuşhan, 2017b;Majumdar et al, 2013;Xu et al, 2017). Multi-phase STFs (MSTFs) have also been investigated in recent years for their better performance in comparison with biphasic STF-impregnated fabrics (Ávila et al, 2018;Gürgen & Kuşhan, 2017a, 2017bGürgen et al, 2016aGürgen et al, , 2016bHuang et al, 2015;Tan et al, 2018). Even though these studies have managed to capture some aspects of the elevated energy absorption capability of STF-impregnated fabrics, their behaviour is not fully understood (Majumdar et al, 2013).…”
Soft armour consisting of multi-layered high-performance fabrics are a popular choice for personal protection. Extensive work done in the last few decades suggests that shear thickening fluids improve the impact resistance of woven fabrics. Shear thickening fluid–impregnated fabrics have been proven as an ideal candidate for producing comfortable, high-performance soft body armour. However, the mechanism of defeating a projectile using a shear thickening fluid–impregnated multi-layered fabric is not fully understood and can be considered as a gap in the research done on the improvement of soft armour. Even though considerable progress has been achieved on dry fabrics, limited studies have been performed on shear thickening fluid–impregnated fabrics. The knowledge of simulation of multi-layered fabric armour is not well developed. The complexity in creating the geometry of the yarns, incorporating friction between yarns and initial pre-tension between yarns due to weaving patterns make the numerical modelling a complex process. In addition, the existing knowledge in this area is widely dispersed in the published literature and requires synthesis to enhance the development of shear thickening fluid–impregnated fabrics. Therefore, this article aims to provide a comprehensive review of the current methods of modelling shear thickening fluid–impregnated fabrics with a critical analysis of the techniques used. The review is preceded by an overview of shear thickening behaviour and related mechanisms, followed by a discussion of innovative approaches in numerical modelling of fabrics. A novel state-of-the-art means of modelling shear thickening fluid–impregnated fabrics is proposed in conclusion of the review of current methods. A short case study is also presented using the proposed approach of modelling.
