In 2017, a video about Chinese bulletproof board went viral on the Internet: an American tycoon who studied bullets bought a Chinese 4-level bulletproof board online. He successively tested it directly with 7.62mm AK bullet and Mosinnagan rifle bullet. As a result, the bulletproof board, which costs only $100, performed very well - it not only blocked all bullets, but even the repeated shooting places were not penetrated! The first hot review of
video was even more eye-catching, "I have reason to believe that some American companies buy Chinese bulletproof vests and then print them in the United States!" I really don't know if they are praising China or scolding the United States. In fact, this is true. Currently, 70% of the world's body armor is made in China. How did the body armor produced in China "counterattack" from a situation where everyone dislikes it?
"Fight to Fame" of Chinese Bombproof Vessels
In 2006, Chinese Bombproof Vessels became famous in the British battlefield. Three years ago, the UK purchased more than 600 body armor from Dacheng Company in our country and devoted itself to the battle against the Saddam regime.
What really made China's bulletproof vests "fire" was the "testimony" from a British man: a team of about 30 people was ambushed by more than 100 enemy troops in the battle. After a tragic escape, their entire team escaped at the cost of a miracle of only one person, and the only dead person was killed by a stray bullet.
One of the soldiers was even shot 12 times by the enemy. However, the impact of these bullets was resolved by the bullets from China. No single shot penetrated the body and caused fatal damage, which was beyond their expectations.
After this battle, everyone in the world saw the strength of China's bulletproof vests and handed over orders to China, and sales soared. At this point, the unknown Chinese bulletproof vests finally embarked on the road of foreign export trade.
However, "easy to use" is not the whole reason for its easy sale. After all, there are so many competitors around the world, and the United States and others are even more like the "original" of body armor. China's technical level at that time was never said to surpass the United States. Why was it sought after by the public?
The answer is very simple. The bulletproof vest produced in China is better than a "cost-performance ratio". Do you still remember the review video we mentioned at the beginning? The fourth-level bulletproof board bought for only $100 is only less than one-fifth of the same performance bulletproof board as the United States. The video blogger even said incoherently: You can buy a Chinese fourth-level bulletproof board as a third-level board, which is more than enough to protect the safety of our civilians.
The price of buying a body armor produced in the United States is to buy Chinese ones, and you can buy four or five pieces. If you are, which one do you choose?
Around 2005, not only Iraq and Israel, the unstable Middle East countries, purchased it to protect the safety of soldiers, but even the United States had to admit: You are still stronger now. Many American soldiers also said that if the military does not intend to buy Chinese body armor, we will pay for it out of our own pocket.
has good performance, is cheap, and even started late. How did Chinese body armor develop like a "cheating"? Why did it be China, not other countries?
Think about it, if you want to talk about high-end technology, it is all distributed in countries such as Europe, the United States and Japan. If you want to talk about population advantages, then our neighboring country India is not bad either. China's counterattack path depends on perseverance and intelligence beyond this. In the history of the development of the body armor of
, a Chinese
body armor appeared, and is also known as the "strongest close-fitting armor", which means that it developed from armor. However, the armor of cold weapons can only block guns and swords, and in the face of bullets with strong penetration, it is immediately not enough to see.
Therefore, the development of "bullet armor" that can replace armor has immediately become a common problem for all countries. Initially, people's minds did not open up and they were still using the idea of making armor to invent the bulletproof vest. The result was that soldiers had to wear 10 kilograms of bulletproof vests made of steel plates on their bodies, and exchange their personal safety with mobility.
A battle was fought, and the bullet "Bangbangbang" hit the steel plate. Not only did this fierce shock damage the soldiers' internal organs and bones, but many tactical actions could not be completed. After using them for a period of time, it can only be said to be miserable.
At that time, some interesting things happened, such as the one who fears death is actually not the soldiers, but the criminals. After the invention of the bulletproof vest, a group of bandits led by Ned Keelly in the UK purchased a large number of bulletproof vests sewn with plows from arable land. They thought they could commit crimes without restraint, but they did not expect that the weight of these bulletproof vests weighed 44 kilograms per piece!
The final result was: Although none of the police's bullets shot through the criminal's armor, they were also thrown to the ground due to lack of mobility, and all the members were eventually arrested. The problem of
was not solved in the 16th century when musket was popular in Europe until the 1860s. An American scientist was "whimsical" and used 10 layers of cotton fiber to create the world's first soft body armor. Later, the silk body armor also emerged and was strongly sought after by various countries.
After that, countries, as if they found their direction, began to develop various "weight-reducing" body armor. Ceramics, alloy steel , aluminum alloy, titanium alloy, nylon... can all become the materials for body armor. The most popular one is aramid made by DuPont in the United States.
There is another special material called Kevla in aramid. It was born in the late 1960s. This material not only has super high strength, but also has good toughness and tensile resistance.
test shows that the Kevlar body armor has the ability to absorb the kinetic energy of shrapnel by 1.6 times that of nylon and twice that of steel. A Kevlar body armor weighing 1.8 kg can withstand close-range shooting of 0.44 mm caliber pistol bullets.
However, Kevlar is a famous brand product of DuPont, the United States. They naturally guard against China. Not only are they technology blocked, but they even embargoed China for a long time. What they are afraid of is that China uses "reverse imitation" technology to learn Kevlar's secret.
But in fact, reverse imitation in the textile industry is far from that easy. Just imagine, even if a piece of high-strength Kevlar fiber is "disassembled", it will be difficult for us to see the tricks from the residual fibers. At most, take a look at the materials.
Since dismantling is useless - not to mention that several countries led by the United States with technological monopoly do not give China the opportunity to dismantle, so we can only study it from scratch.
China has referred to foreign body armor NIJ standards and formulated its own set of standards, using requirements that are stricter than the international average to create its own path. The major domestic private enterprises are not to be outdone and show their own powers.
Take Dacheng Company in Ningbo, Zhejiang as an example. It started research and development in 1995 and became China's first and only modern body armor production base in 2005. It has struggled many times on the brink of bankruptcy, and has achieved some results.
000, when Dacheng successfully conquered new chemical fiber materials, the company had already spent more than 12.5 million yuan, but thanks to this huge amount of money and the unremitting efforts of researchers, they became the fourth company in the world to own this patent.
Correspondingly, my country has also become the fourth country to own this patent after the United States, the Netherlands, and Japan.
What's more amazing is that my country has gradually realized the "one-stop" from raw material research and development to production of finished products. By 2022, looking at the world, only the Netherlands, the United States and China can do it.
However, if it is just fiber, it has a good effect when protecting low-speed bullets, but when encountering high-speed bullets, you will feel a little overwhelmed.
So, the function of bulletproof board is needed here. The above Kevlar fiber is added to the bulletproof board in my country. In addition, there are ceramics, graphene, composite steel plates, plexiglass and other materials that we may have heard of. There are certain material differences depending on the purpose and use environment.
These breakthroughs are not enough by relying solely on private enterprises. my country's domestic bulletproof materials combine the country's large-scale investment in military research and development, the enthusiasm and efforts of various enterprises and sales to jointly develop.
Among them, to transport body armor to all parts of the world, occupying 70% of the market, it is inseparable from the industry that supplies a large amount of raw materials and relies on my country's developed and complete logistics systems. These have greatly reduced the cost of manufacturing, allowing our body armor to have a full foothold in the world with high quality and low prices.
It can be said that whether it is Kevla or other bulletproof materials, although China is not the first country to invent it, it is undoubtedly the country to carry forward it and become the strongest. Such achievements such as
are not only reflected in the bulletproof vests, but in fact, since entering the new century, China has been relying on its extraordinary enthusiasm to start a new high-tech field, from imitation to catching up, from chasing to surpassing, high-speed rail, drone, electric vehicles... all of which are the case.
Next, China's body armor will also enter the fields of graphene and liquid materials. Perhaps one day, China's body armor will not only stay at the first in export volume, but will become the real world's number one. (Source: Popular Science Apocalypse) Contact to delete
