Impact Resistance of Shear Thickening Fluid (STF)/Kevlar Composites for Body Armor Application

A molecular colloidal shear thickening fluid (STF), polyborondimethylsioxane (PBDMS) was synthesized, which differs from traditionally studied Silica/PEG system. Differential Scanning Calorimetry (DSC), the controlled stress rheometer.etc, were used to characterize the produced PBDMS. Scanning Electron Microscope (SEM) is the method to get the surface morphology of the Kevlar fabric impregnated by the fluid. Meanwhile the ballistic and stab tests of the composites materials were investigated.
