title = "The stab resistant properties of Kevlar/STF composites",
abstract = "A colloidal shear thickening fluid (STF) was prepared by dispersing submicron silica particles in Polyethylene glycol 200(PEG200) with ball-milling technique. Kevlar/STF composites were fabricated by soaking Kevlar in the solution of STF diluted by ethanol. The rheological behavior of the fluid with various concentrations and the effect of dilution ratio on stab resistant properties of Kevlar/STF composites were studied. The result shows that the initial viscosity and the highest viscosity of the fluid increase as the weight fraction of SiO2 increasing with the weight fraction ranging from 50\% to 60\%, while the critical shear rate decrease as the weight fraction increasing. The fluid has notable shear thickening behavior at SiO2 weight fraction of 59\%. Two solutions with 1:0.5 and 1:1weight ratio of STF:ethanol were used to fabricate Kevlar/STF composites. It is found that the composites fabricated by solution with dilution ratio 1:1 show better stab resistant properties. The Kevlar/STF composites exhibit better stab resistant properties than the neat Kevlar with the same areal density.",
