NASA invented new metal material automatically repair in two seconds

Remember automatic repair robots in science fiction film? NASA invented a kind of new material, can automatically repair damaged parts in 2 seconds. This material can be used in spacecraft and military aircraft and tank hell automatic
repair.
The Australian news network reported on September 1, although the material is not like science fiction movies the liquid
metal robot in the "terminator", intelligent repair and leave no trace, but it can make a spaceship and military aircraft or
tank automatically repair the damaged shell. Scientists demonstrated in the experiment, with one or two polyester layer
metal after is penetrated, because oxygen entered and mixed with them, polyester liquid rubber containing tributyl borane
(tributylborane) produces chemical reaction, quickly harden and finally repair the damaged parts of the metal.
The researchers said: "this liquid rubber turns into solid after it contacts with air." At present, the material needs to be
studied further, testing its application features. The material is likely to use to repair damaged holes on the spacecraft, as
well as for military equipment, such as plane or tanks.
Besides, according to IFLScience reported on August 27, this self repair material is NASA developed by cooperation with
scientists at the university of Michigan. Jim·Scott (Timothy Scott) of The university of Michigan explaned, this kind of
material cannot be used as components individually, but need to mix with other materials. Scott said: our purpose is to
repair damaged (hole) quickly.
Moreover, the characteristics of the material is, the thinner the faster it will work. In the experiment, the thickness of the
materia plate is 1 mm. In the actual product, the material plate will be thinner, the possible thickness is less than one tenth
or even one hundredth.
