Compared with steel helmets, under the same protective performance, titanium alloy helmets are lighter in weight, stronger in corrosion resistance, and have a long service life. They are still favored by the special police forces of Russia and other countries.
However, due to the high cost of raw materials and processing of titanium alloy helmets, it cannot be equipped in large quantities.
On the other hand, the weight of titanium alloy helmets often exceeds 2kg, and long-term wear will cause damage to the cervical spine. In addition, metal helmets are prone to bullet rebound and ricochet in battle, which can easily cause secondary damage.
In the 1960s, low-density, high-strength aramid fiber materials appeared.
After that, helmets made of aramid fibers gradually became the mainstream equipment of troops of various countries. It can be seen that titanium alloy helmets and aramid fiber helmets have their own advantages and disadvantages, and the composite helmet made of titanium alloy and aramid fiber can combine the advantages of both, which can make full use of the lightweight and high strength of aramid fiber. It can reduce the weight of the helmet without affecting the protective performance, and can also take advantage of the high strength and excellent deformation resistance of titanium alloys to reduce the deformation of the helmet when it is impacted by bullets.
As a high specific strength metal material, titanium alloy has been widely used in body armor and protective armor of armored vehicles, tanks, and other combat vehicles. A titanium alloy/aramid fiber composite helmet can combine the advantages of titanium alloy and aramid fiber material. It is not only light in weight, but also has excellent protection performance, which meets the requirements of individual soldier equipment for helmet weight reduction and protection performance upgrade. It is a modern helmet. It is one of the development trends and is expected to be widely used in the future.
