Abstract Fiber reinforced composite is widely used in current stab-proof equipment, the high performance and light weight have always been pursued for a long time. The present study optimizes anti-stab of fiber composites by using silica silicon carbide ceramic particle reinforcements. different processes structures were characterized. Silica reinforcements added to fabric form shear thickening...

Shear thickening fluids (STFs) refer to non-Newtonian of the dilatant variety, wherein their viscosity experiences a significant surge with an escalation in shear rate. In this investigative work, friction behavior between yarns (pull-out) and absorption static kinetic energy during phenomenon STFs are performed by monophase (MP-STF) adding nano SiO2 dual-phase carbon nanotubes. The ρ-Aramid fa...

This study investigates the effect of multi-walled carbon nanotubes (MWCNT) on high strain rate properties fiber reinforced polymer (CFRP) fabric impregnated with shear thickening fluids (STF). Three GFRP-STF and twelve GFRP-MWCNT/STF composite specimens were conducted using a split Hopkinson pressure bar (SHPB). Spherical silica nanoparticles (20.0 wt%) polyethylene glycol used to prepare sili...

By introducing a state variable, we construct a phenomenological fluid dynamical model of a dilatant fluid, i.e., a dense mixture of fluid and granules that shows severe shear thickening. We demonstrate that the fluid shows shear thickening oscillation, namely, the fluid flow oscillates owning to the coupling between the fluid dynamics and the internal dynamics of state. We also demonstrate tha...

Abstract This paper analyzed the influence of various components and external environment on rheological properties shear thickening fluid (STF). The single-factor experimental study was carried out with silica particle size, mass fraction particles, continuous phase’s average molecular weight, temperature as influencing factors. Obtain factors initial viscosity, critical rate, period ratio STF...

the effect of weak shear thickening and shear thinning on the stability of the taylor-couette flow is explored for a carreau-bird fluid in the narrow-gap limit. the galerkin projection method is used to derive a low-order dynamical system from the conservation of mass and momentum equations. in comparison with the newtonian system, the present equations include additional nonlinear coupling in ...

In this research, the rheological properties of non-Newtonian shear thickening fluid (STF) composed nano-sized solid particles have been investigated. The best conditions determined by optimizing both experimental production method and measurement system STFs. Mechanical, ultrasonic, mechanical ultrasonic mixing methods were used in STFs that silica particle (solid: aerosil) polyethylene glycol...

Shear thickening fluids (STFs) have been shown to improve the effectiveness of fabrics used in soft body armor applications. They are increase puncture and ballistic impact resistance Kevlar® fabrics. However, effect using STFs with natural such as flax appears never studied. Similarly, hybridization different fabric types impregnated STF has also only undergone limited study. The rheology at v...

Dense particulate suspensions exhibit a dramatic increase in average viscosity above a critical, material-dependent shear stress. This thickening changes from continuous to discontinuous as the concentration is increased. Using direct measurements of spatially resolved surface stresses in the continuous thickening regime, we report the existence of clearly defined dynamic localized regions of s...
