“…Silica is a primary choice as a solid phase for STF production [ 16 , 33 , 34 ], but other raw materials such as corn starch [ 35 ], calcium carbonate [ 36 ], titanium dioxide [ 37 ], polymethyl methacrylate [ 38 ], polystyrene [ 39 ], or ethyl polystyrene acrylate [ 40 ] are also used for this purpose. The continuous phase of an STF is usually ethylene glycol [ 41 , 42 ], poly(ethylene glycol) [ 32 , 43 , 44 ], propylene glycol [ 41 ], or poly(propylene glycol) [ 7 , 45 , 46 , 47 ]. There are also reports on the application of glycerin [ 48 ], ethanol [ 37 ], and even water [ 49 ].…”

This work focuses on shear thickening fluids (STFs) as ceramic–polymer composites with outstanding protective properties. The investigation aims to determine the influence of raw material parameters on the functional properties of STFs. The following analyses were used to characterize both the raw materials and the STFs: scanning electron microscopy, dynamic light scattering, matrix-assisted laser desorption/ionization time-of-flight, chemical sorption analysis, rheological analysis, and kinetic energy dissipation tests. It was confirmed that the morphology of the solid particles plays a key role in designing the rheological and protective properties of STFs. In the case of irregular silica, shear thickening properties can be obtained from a solid content of 12.5 vol.%. For spherical silica, the limit for achieving shear thickening behavior is 40 vol.%. The viscosity curve analysis allowed for the introduction of a new parameter defining the functional properties of STFs: the technological critical shear rate. The ability of STFs to dissipate kinetic energy was determined using a unique device that allows pure fluids to be tested without prior encapsulation. Because of this, it was possible to observe even slight differences in the protective properties between different STFs, which has not been possible so far. During tests with an energy of 50 J, the dissipation factor was over 96%.

“…The rheological mechanism of STF is complex. The rheological properties of STF are affected by many factors, such as particle loading, 15 particle shape, 16 particle size, size of the dispersed phase, particle hardness, 17 temperature, 18,19 viscosity of the dispersing medium 20 and additives. 21 The rheological behavior of STF can be analyzed through numerical analysis and finite element modeling.…”

This study reveals the finite element modeling of mechanical failure behavior of shear thickening fluid (STF)/fiber composites under impact. Numerical analysis and finite element modeling of the rheological properties of non-Newtonian fluid, STF are introduced. This review summarizes the model coupling methods in finite element modeling and the mechanical failure behavior prediction models of STF/fiber composites under impact. Further, the influencing factors on the accuracy of mechanical failure simulation models are analyzed. Factors such as the friction between fibers, shear rate, filler particles in the fibers, hysteresis effect and the boundary conditions should be considered in simulating the shear thickening effect of the composites.

“…At high temperatures, a type of fluid known as phase change liquid (PCL) will solidify and serve as a proppant to prevent fracture closure. The second non-phase change liquid (NPCL) undergoes no phase shift during the fracturing process and functions similarly to standard fracturing fluid [14]. investigated the effects of hydroxyl groups and oxygen atoms on the rheological and electrokinetic features of shear thickening time as a function of chain length and branching of carrier fluid (STF).…”

The most frequent viscosifier used in hydraulic fracturing fluid design is guar and its derivatives. However, Guar leaves residues in solution, it is unstable at higher temperatures, and is not immune to market dynamics of demand and supply. This research aims to source for an alternate hydrocolloid for hydraulic fracturing fluid development. Detarium microcarpum (local), Cyamopsis tetragonoloba(imported) and polyanionic cellulose-regular PAC-R (Imported) were sourced, isolated, and used in carrier fluid design. The rheological properties of the three fluids were investigated at 27°C, 57°C, and 85°C. The rheological models were generated and compared with the imported samples as the control. Also, to analyse the proppant handling capacity of each of the carrier fluids, the geometry of the proppant grains and the rheology of the carrier fluids were used to compute the coefficient of drag, the drag force and the settling velocity of the carrier fluids.
