Bulletproof helmet is an indispensable protective equipment in many militaries, security agencies and defense departments. I believe everyone is no stranger to bulletproof helmet. So how much do you know about bulletproof helmets? Let me briefly introduce:

Bulletproof helmet is a high-strength tactical helmet made of special materials such as Kevlar and PE that can defend against bullet attacks to a certain extent. But many people have a certain misunderstanding about bulletproof helmets, they think that bulletproof helmets are completely resistant to bullets. This phenomenon is not difficult to understand, because the word bulletproof itself is misleading to a certain extent. It means that it cannot be penetrated by bullets. In fact, there is no bulletproof equipment that cannot be penetrated. When the bullet is powerful enough and the number of shots is high, any bulletproof helmet can't resist.

There are many synthetic materials for bulletproof helmets, mainly aramid, PE and bulletproof steel. Among them, aramid and PE are new high-tech synthetic fibers developed in the 1960s and 1980s. Compared with traditional bulletproof steel, they have the advantages of light weight and high strength, so they have been widely used in the production of bulletproof helmets. Aramid and PE helmets under the unified protection level are much lighter in weight than steel helmets, but they are also relatively expensive. In addition, limited by the characteristics of the material itself, aramid and PE helmets also have certain requirements for storage. For example, aramid helmets should avoid prolonged exposure to sunlight and contact with water, etc.; while PE helmets should avoid contact with high-temperature objects, etc. .
