What is the shell in your impression? A small slice, thin and crisp? Then you are wrong. In fact, the shell has a natural laminated structure. Because its shape conforms to the principles of mechanics, it uses the least material to construct a very hard shell. This is the magic of nature.
For centuries, scientists have been committed to transforming natural wisdom into daily applications.
In the Super New Materials Science and Technology Park in Baoshan, Shanghai, a new type of "ene" baby-olefin carbon aluminum alloy, which was born out of the sky, borrowed the laminated structure of shells and adopted China's independent innovation of "micro-nano laminated powder metallurgy" Technology has led China into a lightweight era.
This unique biomimetic composite technology comes from the key scientific research team of Shanghai Jiaotong University. The principle is to make aluminum into micro-nano flake powder, and then uniformly compound it with carbon nanotubes and graphene into a "brick" at the microscopic scale. Like the barrier wall, it forms a "brick-built" laminated structure of carbon aluminum alloy material. In order to transform the technological achievements into physical production, the scientific research team continued to practice in the pilot workshop of Baoshan Super New Material Science and Technology Park. After more than 700 days and nights, the first batch of large-scale carbon aluminum alloy was successfully completed in April 2019. Ingot production.
With its unique mechanical properties, graphene endows carbon aluminum alloys with unparalleled lightweight advantages. This pioneering technology in China will also have broad application potential in aerospace, aviation, transportation, defense and other fields.
