bulletproof https://www.somogear.com/ Bulletproof Vest It is also known as protective body armor, is used to pr otect human body from bullet or shrapnel. Bulletproof vest mainly consists of jacket cover and bulletproof layer. Clothes sets are usually made of chemical fiber. The bulletproof layer is made of metal(special steel, aluminum, boron carbide, silicon carbide, alumina), glass fiber, nylon(PA), KEVLAR, ultra-high molecular weight polyethylene fiber, liquid protective materials etc, which can form a single or compound protective structure. New Ceation of Bulletproof Scientists at the university of Southampton have created a bulletproof vest made from fibers extracted from liquid crystal. During the experiment, the researchers found that when a voltage was applied to a layer of crystals, all the liquid crystals, all the liquid crystals aligned in the same direction, forming a long chain of molecules. Use chemical means to make crystal molecular chain t...
