The rheology of shear thickening fluids with various ceramic particle additives

摘要

In this paper, shear thickening fluids (STFs) and three different types of additive particles such as silicon carbide, aluminum oxide and boron carbide are presented. STFs were fabricated based on nanosize fumed silica suspended in a liquid medium, polyethylene glycol at a constant concentration of 20 wt%, and then varying amounts of different types of particle additives were added. Their rheological properties under various temperatures were tested using a rheometer, and the effects of silica loading on the rheology of pure STF were investigated. The suspensions exhibited different systematic variations with respect to the varied parameters. (C) 2016 Elsevier Ltd. All rights reserved.
