Prediction models for the viscosity curve of a shear thickening fluid (STF) over a wide range of shear rate at different temperatures were developed using phenomenological and artificial neural network (ANN) models. STF containing 65% (w/w) silica nanoparticles was prepared using polyethylene glycol (PEG) as dispersion medium, and tested for rheological behavior at different temperatures. The experimental data set was divided into training data and testing data for the model development and validation, respectively. For both the models, the viscosity of STF was estimated for all the zones with good fit between experimental and predicted viscosity, for both training and testing data sets.

Rheological behaviour of shear thickening fluid (STF) is influenced by particle size, particle shape, concentrationof particles etc. This study deals with the effect of particle size and its distribution on the rheological behaviour of STFs andensuing impact resistance of Kevlar® fabrics treated with them. Synthesis of submicron sized silica particles of three differentsizes was carried out by following the Stöber method. Corresponding STFs consisting of 67 % silica particles were preparedand their rheological behaviour was evaluated. Decrease in particle size coupled with particle size uniformity significantlycontributes to enhancement in dilatancy of STFs. Further, Kevlar® fabric was impregnated with these STFs for assessing theirimpact resistance performance. Fabric impregnated with STF prepared from the finest and uniform silica particles, having thehighest peak viscosity, exhibited the best impact resistance performance among all STF impregnated fabrics. These findingsshow that the particle size and its distribution decisively influence the thickening behaviour of STF which in turn plays acritical role in determining the impact energy absorption by high-performance fabrics.
