Physicists have created material for body armor based on the shell of lobster

Physicists from the Massachusetts Institute of Technology have created a durable material for filling body armor based on the abdominal shell of lobsters. They described their invention in the scientific journal Matter .

During dinner, scientists noticed the unusual structure of the abdominal shell of this species of crustaceans. It consists of alternating layers of nanoparticles, which are arranged in a kind of plywood sheet, the layers of which are twisted into a spiral. Despite the fact that the material is a hydrogel, it is highly durable.

Engineers tried to reproduce the structure of the shell using man-made materials. They laid the plates of hydrogel and nanofilaments in several layers, exactly repeating the structure of the crayfish shell. After that, the filler was inserted into the body armor and tested with a laboratory gun.

It turned out that the new material is only slightly inferior to the plates of Kevlar, a synthetic polymer used in modern body armor. When stretched, the new material becomes even stronger, and when a bullet hits it, it noticeably extinguishes its energy.

“Our 13mm layer of material can stop a 5mm steel bullet fired from 200 meters away. In this respect, it is somewhat inferior to Kevlar, but noticeably surpasses it in many others, ”said one of the developers of the material, David Weisset.

Scientists hope that the material will be used not only as a filler for body armor, but also in medicine – it can be used to create artificial muscles, cartilage and other organs that require special strength and flexibility.

Earlier it became known why in nature there are no rabbits the size of a horse.
