| The armor is a flexible material that differs from the stiff Kevlar vests troops currently wear, and it could also be used to protect parts of the body the current armor cannot.
Researchers at the University of Delaware developed the armor by treating Kevlar with a liquid containing millions of tiny glass or ceramic particles. The flexible armor becomes immediately stiff when agitated or hit by a sudden impact.
"The particles jam up, forming a logjam structure that prevents things from
penetrating through them," says Norman Wagner of the university.
Lab video shows that bullets will penetrate a thin layer of Kevlar, but they bounce right off the treated Kevlar.
