The Impact

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.

Great interest has aroused in developing the next generation body armour based on the incorporation of a Shear Thickening Fluid (STF) into high performance fabrics (Kevlar®, UHMWPE). This innovative technoloy allows for the production of comfortable, flexible, lightweight, stab and ballistic resistant protective garments. This innovative technology allows for the production of comfortable, flexible, lightweight, stab and ballistic resistant protective garments. The furrent research was undertaken to evaluate the stab resistance and the chemical properties of types of high performance fabrics, Kevlar and Ultra Hight Molecular Weight Polyethylene (UHMWPE), impregnated with several types of shear thickening fluids. The stab resistance properties of all samples were tested using drop tower and quasistatic testing apparatuses. Chemical compositions and microscopic structures were analyzed with Fourier Transform Infrared Spectroscopy, Scanning Electron Microscopy and Energy Dispersive Spectroscopy. The current study demonstrated the importance of incorporating Shear Thickening Fluid into woven high performance fibres. The results clearly display a significant enhancement in puncture resistance ony of Kevlar® fabrics impregnated with different combination of STFs.
