The cellular structure with a negative elasticity will help to develop a new kind of impact protection Bashny.Net

Researchers from the School of Engineering im.Kokrelya relating to the University of Texas, придумали cellular structure , which absorbs blows, and after exposure is fully restored. Called honeycomb structure with a negative elasticity.



Conventional cellular structures are commonly used in areas related to protection against blows. Jumpers cells absorb the energy of impact, and the presence of voids provides light weight. The only disadvantage of such a structure - Disposable. It manages to absorb the energy to cells only once.



Dodgy system wavy bridges in the new cellular structure ensures its compressibility as well - a full recovery after the disappearance of the force. Such a structure may be used in a wide range of devices, from helmets to car bumpers.

Dimensions of cells affect the power of the impact that the structure can absorb. 9-inch laboratory model fully absorb the impact of a baseball flying at a speed of 160 km / h. The sample is made of nylon, although it fits a variety of materials.

"Do you wear a uniform soldier, practiced sports or riding a bike to work, you can always run into something or get a hit - said Professor Carolyn Conner Sipersed. - We are confident that this technology is being integrated into the bumper and helmets can reduce or completely prevent the injury that get people ».

In the near future, the laboratory will begin testing the absorption of energy bullets.
