“…Chu B et al reported that the heat treatment could affect the interparticle interactions by changing their surface chemistry, and thus further affect the macroscopic ST behavior of the suspensions [20]. Yu et al demonstrated a great effect of particles surface treatment on increasing the maximum mass fraction in the STFs [21]. As described above, rheological properties of suspensions were related to the dispersed particles' structure.…”

In this work, shear thickening (ST) performance of a novel suspension of porous silica nanoparticles was systematically studied. The porous silica nanoparticles which were synthesized by using CTAB as a pore-forming agent were dispersed into ethylene glycol to form shear thickening fluid (STF). Both the steady and oscillatory shear rheological properties of the STF were characterized. The STF showed distinct ST effects when the concentration of the porous nanoparticles was only 42.5 wt%. This value was much lower than the previously reported STF prepared by non-porous particles. The viscosity increased from 0.80 to 14.3 Pa s by increasing the shear rate from 0.1 to 49.4 s -1 , while a noticeable overall downward trend with a high initial viscosity was found in the prepared suspension of non-porous silica. The results indicated that porous nature of the silica nanoparticles could remarkably influence the ST effect. A possible enhancing mechanism was proposed and it was found that the difference of macroscopic rheology behavior was mainly according to interfacial interaction between the porous silica nanoparticles. This work provided valuable information for understanding the relationship between the porous characteristics and ST behavior.

High‐velocity impact performance of shear‐thickening fluid/kevlar composites made by the padding process

et al. 2018

View full text Add to dashboard Cite

Padding is known to enhance the dyeing of fabric. In this study, shear‐thickening fluid (STF)/multilayer Kevlar composites were constructed through a padding process. This paper describes the padding process used, and discusses the ballistic impact and stab resistance of the resulting composites. Padding STF into Kevlar fabric is better than impregnation. The resulting composites are thinner, lighter, and more flexible than conventional Kevlar body armor, while providing similar protection. Previous studies have shown that padding improves the low‐velocity impact resistance of single‐layer Kevlar. This study demonstrates that padding also improves the high‐velocity impact performance of STF/multilayer Kevlar composites. POLYM. COMPOS., 40:3040–3049, 2019. © 2018 Society of Plastics Engineers
