The walls of the building during the explosion scatter into pieces that can injure or even kill a person. The US military invented unique protective wallpaper that prevents the possibility of injury from shrapnel. The wall covering consists of a special adhesive substance, which is reinforced with kevlar fibers. The material very quickly adheres to the walls, and its strength significantly improves the safety performance of the shelter.
Kevlar base
Kevlar is used in various fields. It is used in the creation of sailing vessels and protective suits for bomb technicians. The beneficial properties of Kevlar are high tensile strength relative to mass. This is higher than the figures have become more than 5 times.
These wallpapers have catching qualities, so they increase the strength and reliability of the wall. They were investigated by direct hit of the nucleus. Thanks to the tests, it became clear that the material copes with the protection of brick and cinder blocks. The experiment consisted of several strikes of great power, but the wall was never broken. With minor impacts, the impact force is absorbed, and during strong shocks the wall begins to bend.
Development passes the first tests
“While the project is undergoing the first tests, it doesn’t even have an official name. But we hope that in the near future the development will be put into mass production and will protect thousands of people around the world,” military researcher Nick Boone from the United States of America shared his impressions.
Justin Bronk said that such an idea is not the first, but it has significant advantages over other studies. The material can be quickly and easily applied to a variety of surfaces: this task will cope anyone who has ever pasted wallpaper.
For the first time, the development was presented at the Lab Day exhibition along with new bullet-proof vests of increased flexibility, which will be put into service in the near future. Also at this exhibition presented the development of a medical nature, protective helmets and various modern weapons for military structures.
