A Review on Stab and Spike Resistance Performance of Shear Thickening Fluids (STF) Impregnated Fabrics

Abstract

Abstract-This paper provides a brief review on relevant literature related to shear thickening fluids (STF) impregnated fabrics on stab and spike resistance performance. Soft body armours consist of multiple layers of high performance fabric to stop stab and spike threats. To reduce the number of fabric layers on soft body armours, STF has been introduced. STF transforms from liquid state to a solidlike state under applied stress and return to its original state after stress is removed. Hence, several studies were conducted to enhance the stab and spike resistance of fabrics by exploiting STF unique properties. The performance of STF-fabric that affected by several factors, such as fibre properties, fabric architectures, STF rheological properties (particles size, shape and solid volume fraction), STF synthesis and impregnation process will be reviewed in this paper.

Polymeric Nanoparticles in Drilling Fluid Technology

“…Similarly, it has reported that particle shape has significant effects on drilling fluid properties such as fluid loss and rheological behaviors [24]. Whereas rods and plate shaped sharp-edged particles by jamming and interlocking can cause quick thickening [25] in fluids, flow would be negatively affected. Nanospherical polymeric particles would build viscosity less aggressively, in addition to enhancement of rheology (Figure 5).…”
