Can Bulletproof Helmets be Made Solely of PE Fiber?

As is well known, in practical combat, bulletproof vests can usually effectively reduce the kinetic energy of bullets and avoid causing too much harm to the human body. From this, it can be seen that bulletproof vests still have a certain bulletproof effect.

    As is well known, in practical combat, bulletproof vests can usually effectively reduce the kinetic energy of bullets and avoid causing too much harm to the human body. From this, it can be seen that bulletproof vests still have a certain bulletproof effect.

    Since bulletproof vests can be bulletproof, but helmets cannot function as bulletproof on the battlefield, why not use bulletproof vest materials for helmets? Would that be more defensive than existing helmets? In response, British experts conducted a detailed analysis on well-known forums. It is fully proven that if bulletproof vests are used to manufacture helmets, the performance of bulletproof helmets will be worse.

    The true purpose of soldiers wearing helmets is not to be bulletproof, but to prevent damage from bombs and shrapnel on the battlefield. With the development of military technology, modern soldier helmets are equipped with individual combat systems. However, bulletproof vests can only effectively reduce the kinetic energy of bullets and offset some of their power. If you want the bulletproof vests to block rifle bullets, you need to place a bulletproof plate on top of the bulletproof vests.

    The manufacturing material of bulletproof vests is mainly made of UHMWPE fiber woven fabric through multi-layer stacking, and its working principle is actually somewhat similar to non Newtonian fluids. When a bullet hits a bulletproof vest, the fibers are stretched under force. When the force of bullets is strong, reaching the maximum force that the fibers can withstand will cause deformation. If the bullet's power is small and within the range of the bulletproof vest, it will intercept the bullet.

    From this, it can be seen that even though bulletproof vests can effectively block bullets, during the operation of bulletproof vests, the body will still suffer certain injuries, only minimizing the damage. That is to say, in general, when using bulletproof vests, we still need to use bulletproof plates to avoid unnecessary injuries. Although the working principle of helmets and bulletproof vests is different, their purpose is the same.

    Although modern soldier helmets also use fiber materials from bulletproof vests, they are not entirely made of fiber and are often paired with other materials. It should be noted that under the strong kinetic energy of bullets, if a pure PE helmet is used, although the helmet will not be broken, the soldier's head will inevitably be greatly damaged. And we all know that the head is the most vulnerable part of the human body. If we only use bulletproof vest materials to make helmets, what consequences will be!
