According to foreign media reports, in recent years, the body armor technology worn by soldiers and law enforcement personnel has matured. At present, the latest nano-science technology of the Massachusetts Institute of Technology and Rice University is expected to develop new body armor. The latest nano super materials are as thin as paper. , But can effectively block bullets.
The US research team recently developed a nano-material that is as thin as paper and can effectively block bullet collisions
The team of mechanical engineering and materials scientists from the Massachusetts Institute of Technology and Rice University has recently developed a special material that can block the flight of bullets in the laboratory and resolve the impact of bullet collisions. The research team members include: Rice University research scientist Li Zaihuang (transliteration) and Dean of Engineering Branch Ned Thomas, the research report was published in the recently published "Nature Communication (Abstract Edition)" journal.
This material is called a structured polymer composition. It can be self-assembled with an interactive glass layer and a rubber layer. It has been subjected to live bomb testing at the MIT Nanotechnology Institute. This 20-nm-thick ballistic material layer can block 9 mm. The diameter bullet is fired.
However, one of the challenges facing scientists is how to make thinner and lighter bulletproof devices in the laboratory. Researchers need to know precisely the nanomaterial layer to disperse bullet impact energy well. Currently, structured polymer synthesis It still takes some time to complete the test of the object.
Therefore, this research team proposed an innovative test method. They shot tiny glass balls on this material. Although these glass balls are only one millionth of a meter in diameter, they can simulate the impact of bullets. Under a scanning electron microscope, this layer of material looks like a wick, so the projectile effect can be seen very clearly.
This nano-material helps to improve the impact resistance of bullets and can be used to make new body armor. According to the researchers, this advanced technology can also be used in protective coatings for artificial satellites and even in turbine blades of jet aircraft.
