Structural design of body armor and problems faced

Since modern times, with the update and iteration of thermal weapons, their lethality to the vital force has gradually increased, so "how to reduce the loss of vital force" has become an issue that cannot be ignored. This undoubtedly provides a broader platform for the development of Ballistic vests. In addition, the reckless terrorism and rampant terrorists in recent years have also expanded the use of Ballistic vests from the military to the police. Therefore, body armor itself is bound to experience rapid growth in diversification and iteration.

Problems facing the development of body armor

Ballistic vest mostly uses synthetic ultra-high molecular weight polyethylene fiber or aramid fiber as the main material. During use, these materials will age due to the influence of external environmental changes such as sunlight, temperature, and humidity, resulting in a significant decline in ballistic performance. In general, after 2000 hours of sunlight exposure, the tensile strength will drop to 20% of its original value. In addition, the impact of temperature on the life of bulletproof fibers cannot be underestimated. If the temperature is lower than 10°C or higher than 240°C, the strength of the bulletproof material will be greatly reduced. Especially after a part of the material is violently impacted by the warhead, the temperature can easily exceed 240°C. The influence of Ballistic vests is not only reflected in the natural environment but also in the user's internal environment. Wearing bulletproof vests is usually accompanied by strenuous exercise. If the moisture dissipation ability of bulletproof vests is relatively poor, sweat cannot be excreted from the body in time, and the strength of bulletproof fibers will be greatly attenuated after being wet.

For the human body, most of the important organs are distributed in the torso. If the torso is injured, the probability of death will be very high. At present, the protective parts of the Ballistic vest are generally on the vital parts of the human torso from the throat to the waist, which is why the body armor is often called a "Ballistic vest". However, its protective area is still far from meeting the requirements. The limbs of soldiers on the battlefield are still exposed. If they are unfortunately shot, it will also lead to a reduction or loss of combat effectiveness. However, the limbs are the key parts that determine the flexibility of the human body. Once protected, it will undoubtedly affect the mobility and flexibility of soldiers in combat, thereby reducing the overall combat capability. Therefore, how to improve comfort and flexibility as much as possible while increasing the protective area is the second problem to be solved urgently.

Modular Structure Design of Body Armor

The modular structure design is adopted to strengthen the functional integration of the Ballistic vest. The method of integrating body armor and carrying equipment reduces the number of varieties, reduces the load on individual soldiers, and avoids the problem of duplication of functions, truly realizing the integration of body armor and multi-purpose clothing. The modularity of the portable equipment is simply a universal accessory bag connection system. A wide variety of accessory bags provides soldiers with more sub-packages and component choices, which is convenient for them to flexibly configure and arrange various equipment and weapons, and ammunition according to mission needs. It makes individual equipment more systematic and can cope with different mission environments. In addition, different equipment can be selected according to different tasks. For example, a heavy-duty Ballistic vest is required to protect it well. Long-distance penetration requires lightweight vests that allow for rapid deployment and strategic maneuvering.
