Military Develops Liquid Body Armour

The US Army Research Laboratory has developed a new liquid body armour. According to Dr Eric Wetzel, the project coordinator: The key component of liquid armour is a shear thickening fluid. STF is composed of hard particles suspended in a liquid. The liquid, polyethylene glycol, is non-toxic, and can withstand a wide range of temperatures. Hard, nano-particles of silica are the other components of STF. This combination of flowable and hard components results in a material with unusual properties
