Abstract

This research aims to participate in producing body shield that can overcome pervious drawbacks using behaviour of shear thickening fluid. Initially, the rheological behaviour of silica-polyethylene glycol shear thickening fluid is examined at different concentrations. Then, ballistic fabric samples are impregnated into silica-polyethylene glycol shear thickening fluid at various concentrations of silica and tested using gas gun simulating real ballistic threat. After that, the impact of rubbery hot water pack filled with around 66.67 wt% starch in water is tested using gas gun. Results showed as the concentration of silica increases, the indentation depth in the impregnated fabric decreases which may result in improving performance of ballistic fabric to 12.5 % in case of using 60 wt% silica, 7.35 % in case of using 30 wt% silica and 3.31 % in case of using 7.5 wt% silica with respect to plain sample. As it showed that no indentation depth is formed in modelling clay when rubbery hot water pack filled with around 66.67 wt% starch in water is tested using gas gun causing improvement percentage to be 100% compared to plain sample of Twaron (CT 714).
