“…Gürgen et al 32 has thoroughly reviewed the applications of STF for protective applications and therefore, the present work will only briey describe this aspect. STF has been explored and used for low velocity impact applications, 81,82 stab and spike protection [83][84][85][86][87][88][89][90][91][92] as well as for high velocity ballistic impact applications. 17,93,94 Shear thickening uid (STF) is a non-Newtonian uid having two phases, namely dispersed phase and dispersion medium.…”

“…Unfortunately, thorough understanding of the exact role of STF to enhance the impact resistance of highperformance fabrics is still quite obscure. Some researchers argue that increased friction is responsible for enhanced impact performance, 32,33,90,147 while others believe that the inherent shear thickening phenomenon also plays a vital role in energy absorption. 16,82,83,137,[148][149][150] In their attempt to understand the STF-fabric interaction mechanism, Majumdar et al 68 studied the stage-wise deformation pattern on neat and STF treated fabrics.…”

“…2. An extruded polystyrene (XPS) foam block, which provides fair penetration for the impactor rather than blunt impact due to its brittle structure, was placed under the fixture as suggested in [17][18][19]. Each impact case was tested by three repetitive fair impacts, and the average of the results were reported in this paper.…”

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.

“…Due to this unique behavior, this smart fluid has been adapted to various engineering applications. In early studies, STF treated high performance fabrics that were tested against different threats, such as needles [1], spikes [2,3], knives [4,5] and projectiles [6,7], to benefit from the shear thickening rheology for stopping the attacking threats. Although STF contributes to the protective performance of textiles, there is a complicated mechanism in STF/textile composites to clearly understand whether shear thickening rheology alone is useful for protection.…”

Shear thickening fluid (STF) is a very interesting and promising material in several application fields where a different mechanical is demanded based on loading rates, like body armor and vibration insulators. Cork is a natural cellular material by excellence, filled with well-known beneficial effects in terms of insulation and also interesting crashworthiness properties. In this work, cork grains of very small size (0.5-1.0 mm) are added to two different shear thickening suspensions, one of them a fully natural water and cornstarch, and the other based on fumed silica and polyethylene glycol. The rheology of these ecofriendly suspensions was investigated and the influences of including cork grains were discussed. In addition, microscopic analyses were carried out to observe the deformations at each component during the shear thickening phenomenon. Cork grains reduce the load-carrying capacity in the suspensions due to the deformable characteristics of cork. For this reason, shear thickening properties are suppressed in the mixtures. Despite this, it is possible to state that viscosity increase in the mixtures leads to strong particle contacts, and thereby resulting in particle deformations in the main constituent powder as well as in the cork additives due to their softer structures.
