Remember the auto repair robot in science fiction movies? NASA invented a new material that can automatically repair damaged parts within 2 seconds. The material may be used for automatic repair of spacecraft and military aircraft and tank casings.
The Australian News Network reported on September 1 that while this material cannot currently be smartly patched like the liquid metal robot in the sci-fi movie Terminator without leaving any traces, it can automatically repair spacecraft and military aircraft or tanks. Broken shell.
The scientists demonstrated in the experiment that after the metal with one or two polyester layers was penetrated, because the oxygen entered and mixed with it, the polyester liquid glue containing tributylborane chemically reacted and changed rapidly. Hard, and finally repair the damaged parts of the metal.
The new material can automatically repair damaged parts within 2 seconds.
Researcher personnel said: "This liquid glue and air contact for a few seconds, that is, from liquid to solid state." At present, the material still needs further research to test its application characteristics. This material is very likely to be used to repair damaged holes in spacecraft, as well as for military equipment such as aircraft or tanks.
According to IFLScience on August 27th, this self-repair material was developed in collaboration with NASA and scientists at the University of Michigan. Timothy Scott of the University of Michigan explained that this material cannot be used as a component alone, but needs to be mixed with other materials. Scots said: "Our goal is to quickly repair (broken holes)."
Moreover, the material is characterized by the thinner the faster the effect. In the test, the thickness of the material plate was 1 mm. In an actual product, the material plate may be thinner, and may have a thickness of one tens or one hundredth of a millimeter.
