Infrangible rebar is a rebar with new material to prevent breakage in earthquakes, keep people from being crushed and gain more time for people to escape. It looks like a normal rebar, filled with material ranged between solid and liquid substances, called Non-Newtonian fluid. The material has strong adhesion and toughness. When exposed to air, it will solidify rapidly, and a new fixed structure is formed. With this special nature, when building collapses, infrangible rebar’s outlayer steel breaks first. Then the inner layer of infrangible material undertakes the weight with high toughness. Soon it solidify into a new fixed structure.
