Why Can Body Armor Block Bullets? Answer For You

Body armor is clothing worn by soldiers to protect their bodies from enemy bullets while on duty. At present, the best performance bulletproof vest in the world is the American dragon scale armor bulletproof vest. It was hit 40 times without being shot down by a standard 7.62x39mm military bomb at a distance of 6 meters, and even ordinary armor-piercing rounds couldn't penetrate it. So why can body armor block bullets?
Many people may think that there are special steel plates in the body armor, because only steel plates can block bullets. So is this really the case? A foreigner bought a body armor specially and wanted to dissect the body armor to see if there was any steel plate inside!
It took him a long time to use a hacksaw to disassemble the body armor, but the result was different from what he thought before, because there were no steel plates in the body armor, but layers of Kevlar The fibers are overlapped, and it is found that the fibers are very strong and difficult to tear when torn by hand.
They found the warhead left by the bullet in the previous test, and found that only a little mark was left on the surface, and it didn't even penetrate a layer of Kevlar fiber. This made them feel very incredible. I believe that after seeing this, some people should not say that wearing body armor on the battlefield is useless!
