The Engineers of MIT, Caltech and Eth Zürich have published a new study on the “nanoarchite” documents designed with the help of patterned nanometry structures precisely. The researchers believe that the material could be promising for light armor, protective coatings, blow shields and other shock-resistant materials. The ultra-light material is made with a nanometric carbon leg, which makes the material very hard and giving it strong mechanical robustness.
The material has been tested by pulling with microparticles at supersonic speeds. They discovered that the material prevented the miniature particles from tearing it despite being thinner than the width of human hair. According to the team, compared to steel, Kevlar, aluminum and other comparable weight resistant materials, the new material is more efficient for absorption impacts. Principal Researcher Carlos Portela says the same amount of mass of the new material would be more effective to stop a projectile than the same mass of Kevlar.
If the new material has been large-scale, it could be designed as lighter and harder than other commonly used materials. Depending on the manner in which they are arranged, the nanoscale structures the nanarchitted material is motivated with unique properties such as exceptional lightness and resilience. Portela states that researchers only know the response of these documents in a slow deformation regime. Great practical use is hypotte to be in applications of the real world where nothing is slowly deformed.
His team wanted to study materials in faster deformation conditions, such as high speed impacts. In Caltech, they made a nanaarchity material using the lithograph of two photons. This technique uses a high power laser to solidify microscopic structures in a photosensitive resin. The researchers built a repeated model called Tetrakaidecaedron.
After the structure of this structure, the researchers washed the resin of remains. Then they placed the structure in a high temperature vacuum oven to convert the carbon polymer, resulting in an ultra-licked and architectured carbon material. To test the material under extreme deformation, the team carried out a microparticle impact experience at MIT using laser-induced particle impact tests. For this test, 14 micron silicon oxide particles were used. The team adjusted the particles at speeds from 40 to 1100 meters per second, noting that something supersonic is greater than 340 meters per second. The experiments show that the material can absorb a lot of energy with the particles unable to cross the material.
