Polymer Composites
This study presents STF/Fabric composite configurations by impregnating single‐phase shear thickening fluids (S‐STF) and multi‐phase shear thickening fluids (M‐STF) into aramid fabrics. S‐STFs were first prepared at different concentrations by weight (25%

Rheology of Magnetorheological Shear Thickening Fluids
Advanced Materials Research, 2008This paper presents fabrication and characterizing of a new functional material, magnetorheological shear thickening fluid (MRSTF), by mixing micron-sized magnetizable particles with nano-sized silica particle based shear thickening fluid. Dynamic properties of the MRSTF were characterized by using a parallel-plate rheometer.

Shear thickening in filled Boger fluids
Journal of Rheology, 2005Shear thickening is studied in suspensions consisting of micrometer sized polystyrene spheres dispersed in Boger fluids. In comparison with available data for suspensions in Newtonian media, shear thickening occurs at much lower volume fractions. Suspensions in normal nonlinear viscoelastic media typically do not display shear thickening at all.

Development of a smart rubber joint for train using shear thickening fluids
Smart materials and structures (Print), 2020Developing a train bogie to achieve high speed stability as well as good curve passing performance has always been a challenge. This is because of the conflicting stiffness requirements: stability at high speed calls for a high primary longitudinal ...

Thixotropy of MR shear-thickening fluids
Smart Materials and Structures, 2010Particle sedimentation is a key issue of conventional magnetorheological (MR) fluids. We recently fabricated MR shear-thickening fluids (MRSTF), which can work as novel MR fluids without particle settling. This merit of the material against particle settling is attributed to the thixotropy property.

Study on magnetorheological shear thickening fluid
Smart Materials and Structures, 2008In this paper, a magnetic-field-controlled and speed-activated magnetorheological shear thickening fluid (MRSTF) is presented. We fabricated a kind of shear thickening fluid (STF) which was composed of nanosize silica particles suspended in a solvent, ethylene glycol, at high concentrations.

Shear thinning vs shear thickening in associating fluids
The Journal of Chemical Physics, 1998When one-bond Frenkel dumbbells are allowed to dimerize, as analyzed using the Wertheim theory of association, the resulting fluid exhibits shear thinning or shear thickening behaviors. In contrast, when Gaussian chains undergo shear-assisted association, only shear thickening is possible.

Textile Research Journal
Shear thickening fluid (STF) for personal stab-resistant clothing has been consistently discussed. However, it is not clear whether STF in STF–fabric composite materials undergoes thickening under normal loads, and to what extent. In this study, the yarn pullout test and the knife-stab test in the quasistatic mode were used to establish the ...

Nonlinear fluid behavior: from shear thinning to shear thickening
Physica A: Statistical Mechanics and its Applications, 1994Abstract A phenomenological model is introduced which describes both shear thinning and shear thickening behavior. Consequences of this model are presented for plane Couette (simple shear) flow. The non-Newtonian viscosity and normal pressure differences are discussed for a stationary situation.
