“…A different method was also observed in the works of Haro et al [ 124 ], Jeddi et al [ 174 ] and Kubit et al [ 179 ], as they made use of metallic plates to enhance the ballistic performance of the armor. The first two works [ 124 , 174 ] used Al plates in a sandwich set with impregnated ballistic fabric. The latter [ 174 ], in a different way, used the STF as a filler in an intermediate layer.…”

“…Jeddi et al [ 174 ] used the Al sheets and fiberglass fabrics impregnated with 20 wt% SiO 2 /PEG 400 STF. Different configurations were developed to evaluate the ballistic strength of sandwich composites, which were: four layers of Al (4AL), two layers of Al + five layers of fiberglass fabric (2AL-45Neat), two layers of Al + five layers of fiberglass fabric/STF (2AL-5STF) and two layers of Al + three layers of fiberglass fabric/STF (2AL-3STF).…”

As destructive power of firearms raises over the years, ballistic armors are in continuous need of enhancement. For soft armors, this improvement is invariably related to the increase of stacked layers of high-strength fiber fabrics, which potentially restrains wearer mobility. A different solution was created in the early 2000s, when a research work proposed a new treatment of the ballistic panels with non-Newtonian colloidal shear thickening fluid (STF), in view of weight decreasing with strength reinforcement and cost-effective production. Since then, databases reveal a surge in publications generally pointing to acceptable features under ballistic impact by exploring different conditions of the materials adopted. As a result, several works have not been covered in recent reviews for a wider discussion of their methodologies and results, which could be a barrier to a deeper understanding of the behavior of STF-impregnated fabrics. Therefore, the present work aims to overview the unexplored state-of-art on the effectiveness of STF addition to high-strength fabrics for ballistic applications to compile achievements regarding the ballistic strength of this novel material through different parameters. From the screened papers, SiO2, Polyethylene glycol (PEG) 200 and 400, and Aramid are extensively being incorporated into the STF/Fabric composites. Besides, parameters such as initial and residual velocity, energy absorbed, ballistic limit, and back face signature are common metrics for a comprehensive analysis of the ballistic performance of the material. The overview also points to a promising application of natural fiber fabrics and auxetic fabrics with STF fluids, as well as the demand for the adoption of new materials and more homogeneous ballistic test parameters. Finally, the work emphasizes that the ballistic application for STF-impregnated fabric based on NIJ standards is feasible for several conditions.

“…59 Different from the above structure, in a sandwich panel, the plastic deformation including face-sheet bending and core crushing, usually occurs instead of penetrative damages when subjected to low-velocity impact. 113 Using a drop-weight impact testing machine, Jeddi et al 75 investigated the energy absorption of aluminum sandwich panels with STF-filled 3D fabric cores under low-velocity dynamic compression impact. A cylindrical-head impactor (to perform a surface impact) freely fell from a height to impact the sandwich panels.…”

Fabrics with proper mechanical properties and high structural designability are frequently selected as the reinforcement of flexible composites. Shear thickening materials (STMs), including shear thickening fluid and shear thickening gel, are dense colloidal suspensions exhibiting an abrupt increase in viscosity with increasing shear rate. Shear thickening fabric composites (STFCs) which combined STM with fabrics, have been increasingly in demand for impact protective applications due to their tremendous potential. Herein, the characteristics of STM and the effects of fabric reinforcement on STFC impact behaviors are discussed for optimizing their properties and structures. Subsequently, the impact behaviors of STFCs obtained by multiple testing approaches with different impact threats are reviewed systematically. Furthermore, a comprehensive summary of the existing literature on stab, drop-weight, split Hopkinson pressure bar, and ballistic impact protective mechanisms of STFCs is presented. It is found that based on the proper selection of STM types, thorough mechanistic explanations of STFC impact behaviors are instructive and could facilitate the development of wearable protective equipment. The purpose of this critical review is to provide a framework for comparison of the effective impact resistances of STFCs across many applications and to discuss issues for future research.
