“…Nevertheless, the looser weave of the UHMWPE fabric allows better incorporation of the nanoparticle/PU mixture, and therefore a higher percentage increase in normalized penetration resistance was observed. Such an interpretation is analogous to a similar study that interprets more effective response of innately infirm UHMWPE fabrics to STF-impregnation [15].…”

“…The impregnation of textiles with shear thickening fluids (STFs) is a relatively new approach to improve the penetration resistance of HSFs [15][16][17][18][19][20][21][22]. Interestingly, most of these studies use Kevlar ® fabric and only a few have focused on the use of considerably lower-cost and lighter UHMWPE fabrics.…”

“…For instance, STF-impregnation was a detrimental treatment for penetration resistance (against a spherical-head impactor at 4.5 m/s) of 400-denier UHMWPE fabrics (various thread counts except 25 × 25). On the contrary, STF-impregnation of 1350-denier UHMWPE provides up to 59% higher normalized penetration resistance force [15]. The effectiveness of STF-impregnation on UHMWPE fabric against spike and knife penetration also depends on the choice of dispersing medium used in the fabrication of STF.…”

“…Apart from the varying performances reported, one potential limitation of STF-treatment technology is the propensity of fluid-like STF materials to leakage [17], as they could be easily washed away when exposed to water and moisture [18]. In general, the mechanism of improvement of penetration resistance of STF-treated textiles is a combination of impact energy absorption due to shear thickening phenomenon and also increased inter-yarn friction [15,19].…”

Although considerable research has been directed at developing materials for ballistic protection, considerably less has been conducted to address non-firearm threats. Even fewer studies have examined the incorporation of particle-laden elastomers with textiles for spike, knife, and needle protection. We report on a new composite consisting of ultra-high-molecular-weight polyethylene (UHMWPE) fabric impregnated with nanoparticle-loaded elastomer, specifically designed for spike- and needle-resistant garments. Failure analysis and parametric studies of particle-loading and layer-count were conducted using a mixture of SiC and polyurethane at 0, 30, and 50 wt.%. The maximum penetration resistance force of a single-layer of uncoated fabric increased up to 218–229% due to nanoparticle loading. Multiple-layer stacks of coated fabric show up to 57% and 346% improvement in spike puncture and hypodermic needle resistance, respectively, and yet were more flexible and 21–55% thinner than a multiple-layer stack of neat fabric (of comparable areal density). We show that oxygen-plasma-treatment of UHMWPE is critical to enable effective coating.

“…From this investigation, delamination is related to the through-thickness tensile properties of the structures. Arora et al [7] used a non-Newtonian fluid in an UHMWPE-based textile to enhance the impact resistance of the structure. It was stated that the treated fluid leads to an increase in the frictional interaction between the UHMWPE fibers and thereby enhancing the energy absorption in the structure.…”

Ultra-high molecular weight polyethylene (UHMWPE) is one of important materials utilized against impacting threats. In this work, bulk UHMWPE specimens were fabricated in a compression molding chamber, and molding parameters such as pressure and temperature were varied in the specimen preparation stage to investigate the effect of molding parameters on the impact performance. In addition, silicon carbide fillers were included in the UHMWPE matrix to enhance the antiimpact properties of the specimens. From the results, high molding pressure provides enhanced impact resistance due to improved microstructural consolidation. On the other hand, molding temperature just above the melting point of polymer is much beneficial to the anti-impact behavior of the structures. Carbide fillers lead to an increase in the frictional interaction between the impactor and composites and thereby enhancing the impact resistance of the structures. However, the gain in the protective properties performance is restricted up to a certain amount of carbide loading because at higher filler ratios, the composites change from ductile to brittle characteristics. For this reason, crack growth susceptibility develops in the composites at excessive carbide loadings.

This study reveals the finite element modeling of mechanical failure behavior of shear thickening fluid (STF)/fiber composites under impact. Numerical analysis and finite element modeling of the rheological properties of non-Newtonian fluid, STF are introduced. This review summarizes the model coupling methods in finite element modeling and the mechanical failure behavior prediction models of STF/fiber composites under impact. Further, the influencing factors on the accuracy of mechanical failure simulation models are analyzed. Factors such as the friction between fibers, shear rate, filler particles in the fibers, hysteresis effect and the boundary conditions should be considered in simulating the shear thickening effect of the composites.
