For many, it is no secret how hard it is for those who serve in the army. A soldier’s full uniform sometimes weighs up to fifty kilograms. With such a heavy load on the shoulders to fight is very difficult. Belarusian scientists believe that it is possible to significantly reduce the weight of a bulletproof vest, that is, use ceramics instead of steel in its manufacture. It is hard to believe this, but a couple of years ago at one of the exhibitions in Minsk a group of scientists read a report on the properties of armor ceramics. They suggested using this material for peaceful purposes, in construction and industry. After the report of scientists, the military asked if their invention could be used to create a lighter body armor. And so that he remains a reliable defense for the soldier. The know-how of Belarusian inventors lies in the fact that they proposed to make the armor plate modular, that is, the team, as a designer. The outer layer is a conventional ceramic plate with a thickness of three millimeters. The bullet does not pierce it and at the same time it is deformed and deviates from its trajectory. The second layer consists of ceramic balls or cylinders, filled with a resinous composition. This layer gives the vest flexibility and, due to the rounded surface of the composite components, knocks the bullet out of the way. After several such ricochets, she begins to "jerk" the entire armored plate. As a result, all this to the third layer, consisting of another ceramic plate, gets a clump of lead, not a bullet. Stand it or not - it does not matter. The last layer, consisting of a special durable Kevlar fabric, lead a lump of no more than ten millimeters. That does not threaten the life of a fighter.
The weight of ceramics is about two and a half times less than the specific gravity of steel. The weight of the finished body armor will not exceed ten kilograms. Belarusian development does not require expensive, new equipment. The cost of such a bulletproof vest will be about three hundred dollars.
The tests for which an armor plate was made, consisting of small ceramic plates measuring twenty by thirty centimeters, showed that such a bullet-proof vest according to Russian State Standard meets the third class of protection.
The novelty has not yet been put into production. The developers hope that their invention will find its consumer and will be in demand. So, if we ever meet a soldier in such a ceramic body armor, this will not be surprising.
