Is It Better To Have A Body Armor That Is Lightweight Or Hard?

The function of body armor is related to the safety of human life and should not be underestimated. Some people in the market say how "light" their body armor is, and some say how "hard" their body armor is. The body armor is light. Still hard?
[Lightweight body armor]
Some sellers only talk about how light the quality is when they advertise a certain waterproof level of body armor. In fact, it is an irresponsible propaganda point, because it does not mark the safety protection area of ​​​​the product, and it is of different grades. The material of the jacket also has a certain impact on the overall quality and size of the body armor.
For soft bulletproof materials, there are mainly two types of UHMWPE fiber and aramid fiber at this stage, and the source of the material is one or two foreign manufacturers and domestic UHMWPE fiber without weft. Fabric manufacturers, for this reason, have different materials and the main difference depends on the design concept. The content of the design concept includes important factors such as the product’s safety protection area and insurance index. The larger the safety protection area or insurance index, the higher the quality of body armor with the same waterproof level.
The insurance index is related to the service life of the product and its defense against different destructive power caused by bullet instability factors. Products with a large insurance index have enough power to avoid the decline in safety protection characteristics caused by the long use time and material aging. Moreover, when the destructive power of bullets fluctuates, products with a large insurance index can still guarantee sufficient bulletproof characteristic.
According to the industry standard, the domestic 54-type pistol fires the 51-type bullet with an initial velocity between 420 and 450m/s, but in the testing process, the initial velocity has been greater than 480m/s; The muzzle velocity is between 480 and 515m/s, but there have been cases where the muzzle velocity was greater than 520m/s.
For this reason, it is not comprehensive to broadly say how light the product is, and it should be related to the waterproof level of the product, the protective area and the materials used.
[Hard body armor]
Hard body armor is stable and durable. At the same time, the price of hard body armor is cheap, which is less than half of the quotation of the same soft product. In fact, that is an incomplete perception.
The key factors such as heavy body armor, heat transfer, and incompatibility with the body cause personnel not to want to wear it. If they don't wear it, it means that they don't have auxiliary equipment. At the same time, hard body armor also has disadvantages such as rebound and ricochet, and is undoubtedly a potential source of bullet launch during combat.
It can be seen from this that the auxiliary equipment of hard body armor is not a greater waste of resources and mistakes? Soft goods are the result of technological development and social development and progress. Laminated production and processing and sealed with dark waterproof cloth, suitable for all-day use, small quality, soft, comfortable, is a substitute for hard body armor.
However, at the current stage of unbalanced social and economic development and insufficient funds, auxiliary equipment with appropriate hard body armor can also solve the urgent need.
Therefore, no matter whether it is a light body armor or a hard body armor, it cannot be said that one is better than the other. Because the materials of the products are different, and the main places of use are different, so the choice of body armor should be based on the relevant bulletproof characteristics and the actual site.
