Do bulletproof helmets really protect against bullets?
In fact, the early bulletproof helmet was to protect the head of the soldier, but this is not to say that the bullet can’t penetrate, if the bullet can’t penetrate the bullet-proof helmet, the neck should be unbearable. The biggest role of a bulletproof helmet is actually to protect against shrapnel or splashes. For bullets, if the bullet is not directly hit, because the bulletproof helmet is a curved surface, most of it will slide.
With the change of manufacturing materials, bulletproof helmets are no longer steel products, and the main materials for making bulletproof helmets are ultra-high molecular weight polyethylene fiber and aramid fiber. The use of composite bulletproof helmets, the function has long been not limited to the steel bulletproof helmets of the year. The ultra-high molecular weight polyethylene fiber helmet is more lightweight, and the protective ability is greatly improved, which can effectively prevent the injury of hand gun bullets to the human head.
Bullets and shrapnel were flying across the battlefield… Even in the context of the information network era, this scenario is not uncommon. Individual safety protection is very important, especially for the protection of the head. For soldiers, having a helmet with high protective ability can effectively improve the battlefield survival rate.
