Bullet-proof "cornstarch"

A new impact-resistant composite material that is both flexible and lightweight has been developed by researchers in Singapore. The thixotropic material stiffens, in a similar way to cornstarch solution, when struck. A sheet of the new material just 20 mm thick is comparable in performance to hard ceramic or steel plates used as protective padding in ballistic vests. It could find use in replacing the thick, heavy steel plates worn by soldiers and law-enforcement officers beneath Kevlar body armor so improving mobility and comfort for the wearer.
