Bulletproof Helmet - An Important Component of Individual Protection
As an important component of individual protection systems, bulletproof helmets have been fully recognized for their combat effectiveness in various local wars and high-tech local wars. Currently, many countries are making every effort to develop a new generation of multifunctional and high-performance bulletproof helmets to meet the operational needs of future high-tech warfare.
Bulletproof Helmet - An Important Component of Individual Protection
As an important component of individual protection systems, bulletproof helmets have been fully recognized for their combat effectiveness in various local wars and high-tech local wars. Currently, many countries are making every effort to develop a new generation of multifunctional and high-performance bulletproof helmets to meet the operational needs of future high-tech warfare.
However, bulletproof helmets are not actually bulletproof. They can only withstand fragments, and rifle bullets can easily penetrate various military bulletproof helmets within their effective range, with two eyes. So choosing a helmet with strong protective capabilities is crucial. So, how to measure the protective ability of helmets. The quality of a helmet is usually measured by three indicators: V50 speed value, protective area, and weight. The material is not included in the consideration, it is a helmet made of galvanized iron sheet. As long as the above three indicators are qualified, it is also a good helmet.
The bulletproof index of a helmet is the most crucial, as it determines the fundamental performance of the helmet. V50 is an important indicator that accurately reflects the bulletproof performance of helmets.
The so-called V50 value refers to shooting a helmet at different speeds using a slanted cylindrical projectile with a mass of 1.1 grams within a specified distance. If 50% of the projectile penetrates the helmet and 50% does not, it reaches a 50% probability of penetration. The average velocity of the fired bullet is the V50 value of the helmet. The higher the V50 value, the better the bulletproof performance of the helmet.
Bulletproof helmets are usually used to prevent bullets or fragments. Experiments have shown that the ZTX series high-strength and high modulus polyethylene fibers have excellent bulletproof helmets using thermoplastic resin as the matrix. This type of helmet is lightweight, resistant to ultraviolet rays, and the impact of moisture on it can be ignored.
The protection area of a helmet is also very important. An ideal protection area helmet should be like ancient heavy armor. However, due to weight considerations, modern military helmets cannot achieve this. Therefore, designers try to increase the protection area as much as possible. Therefore, the appearance of advanced helmets in major countries today is similar. As for the weight of the helmet, the lighter the better.
In the future, the killing power of battlefield weapons will be greater, the number of various fragments will be greater, and soldiers will face more serious injuries. For this reason, armies around the world are developing bulletproof helmets with better protective performance.
