China exports the world's most top body armor

China is now the world's largest manufacturer and exporter of personal protective products such as body armor. The Chinese Class IV bulletproof inserts purchased by foreign enthusiasts for only US$100 have successfully resisted the close-range shooting of high-power rifles. The high cost-effectiveness of domestic bulletproof products , Sparking heated discussions overseas.

The current level of personal bulletproof products in China has increased by leaps and bounds, mainly due to two aspects: one is the good environment created by reform and opening up, which not only provides the technical system foundation but also provides an extremely broad market; the other is the current domestic The relevant mainstream companies in China are generally dedicated and competitive. They have made breakthroughs in mid-to-high-end products and are very competitive in the international market.

For example, in the 1980s, China’s self-shaped 81 body armor used aluminum alloy-nylon material; although it is much better than the glass fiber reinforced plastic fiber in the 50s, the nylon material and the contemporary American Kevlar (aramid) material Not far. After the 1990s, China introduced a large number of advanced materials including aramid production technology, which laid the foundation for the development of a new generation of domestic bulletproof products, especially to catch up with the international mainstream and advanced level.

   There is no doubt that Western countries transfer technology and funds to China and provide a large number of foundry orders; the main purpose is to value China's cost advantages in administration, labor, and environmental protection, which can provide them with a lot of profits. However, with this foundation, many domestic related enterprises have obtained opportunities for development and growth, and formed their own late-comer technological advantages, and they have become leaders in market research and development.

   For example, take a company familiar to the author as an example. In the early days, they could only make some FRP body armors with very low protection levels-the main market is related to the domestic banking industry, especially escort companies.

And now, including resin and carbon fiber reinforced boron carbide ceramic ballistic products with complex structures, they can all be made, and they can meet the level IV bulletproof requirements under the NIJ standard with very light weight-and this is a very typical modern A high-end product that can withstand armor-piercing bullets fired by a 7.62mm high-power sniper rifle within 15 meters.

Since the highest level of the NIJ standard is only Level IV, products with higher protection capabilities are customized and tested according to the specified requirements of customers, and are not included in the scope of the standard; the legendary Western-style V-level body armor is more just some Commercial propaganda by Western companies.

Therefore, in terms of the protection capabilities of mainstream body armor products, there is no difference between domestic and foreign products of the same level-everyone follows the same test standard system. The level of qualified products of the same level is reflected in reducing the weight of the entire product as much as possible, reducing the thermal load of the product when wearing, and improving the comfort and flexibility of wearing.

   Compared with Western high-end products, domestic products are often more lagging behind some design in use-such as quick putting on and taking off, or quick access to various firearms in wearing and so on. This is because the domestic environment cannot be compared with foreign countries where there is a huge civilian shooting market in connection with the development of bulletproof products and the progress of the new tactical shooting system.

   The most fundamental gap in the country at present is still reflected in the fact that the foundation of the entire industry is highly dependent on foreign countries. For example, a company mentioned above, their boron carbide bulletproof ceramics, and its sintering equipment need to be imported from France.

For example, the use of shear thickening liquid (STF for short) to strengthen the bulletproof fiber-that is, the rumored "liquid bulletproof vest", the progress of practical and commercialization in foreign countries is faster than domestic. At present, the relevant mechanisms and specific processes in China are still in the stage of tracking research and development.

  Similar to this, including the preparation of ultra-high molecular weight polyethylene fiber, the dependence on imported equipment and even raw materials is difficult to get rid of in a short time. In addition, the exploration of bulletproof products with new principles and new material structures is currently lagging behind in China. Therefore, although domestic bulletproof products have achieved very great results, there is still a lot of room for further efforts to completely get rid of the dependence of upstream equipment on foreign countries.
