Top Bulletproof Wear Fabrics Are Expected To Be Made In Wuhan.

Yesterday, I was told that Wuhan At the just concluded World Textile Conference, textile university has entered into cooperation with University of Manchester, the leading international university in the field of materials, and is about to jointly build the first three dimensional textile technology laboratory in China by the end of this year. Its technology can be widely used in advanced bulletproof clothing, automobile, aircraft and other materials manufacturing, and is expected to break the monopoly of Europe and the United States.

Zhang Shangyong, Professor of the school, said that mankind is in the initial stage of polymer era, and more and more synthetic materials such as carbon fiber and aramid are used in life. Fiber reinforced composites, especially for the developed countries in Europe and the United States, are the leading high-end materials in terms of strength, mildness, wear resistance, shock resistance and permeability. For example, in the application of BMW I8 shell, it can make the car lighter and more fuel efficient. Russia even uses this material to replace steel bars to build flyovers. More direct applications are bulletproof vests and bulletproof helmets. At present, the bulletproof standard of Chinese bulletproof vests can only reach four levels. Europe and the United States have been able to make the top seven class bulletproof vest, many of them use fiber reinforced composite materials, but the technical blockade is carried out outside.

Zhang Shangyong said: "all the clothes used are flat knitting technology, and fiber reinforced composites are three-dimensional textile technology. We are now studying this technology, hoping to eventually produce better bulletproof products, such as bulletproof vests, bulletproof helmets and so on, which can even replace most metal products. This is a breakthrough in the transformation of China's textile industry.

According to the introduction, the bullet proof fabric made of three-dimensional textile technology has special mechanical properties, which can quickly filter and absorb the energy generated by the impact of the bullet, and it is much thinner than the 350 thick bulletproof vest currently on the market. The school speculates that if the project starts smoothly at the end of this year, it is expected that the top bullet proof products will be available in China in 5 to 10 years.

In addition to making bullet proof products on "tall", there are many "ground gas" applications. For example, it can effectively improve the breathable layer of sports shoes, reduce the cost of breathable materials, make sports shoes lighter and more durable, and it can also solve the problems of traditional materials such as cracks in bags.

Zhang Shangyong said: "our strength is talent. Britain urgently needs a large number of doctoral students here to assist in scientific research. We also need advanced textile materials technology in Britain. This is a mutually beneficial and win-win cooperation. "

Why bulletproof vests can be bulletproof?

Why bulletproof vests can be bulletproof?

Bullet proof clothing made of hard materials such as metal, ceramics and other hard materials is mainly based on the phenomena of crushing and cracking when the projectile is struck, thus absorbing a lot of impact energy of the projectile.

Body armor has been developed to the third generation.

If the bulletproof vest is made of high-performance fibers, the bullet proof principle is mainly that the bullet will stretch and shear the fibers, and the impact energy will be transmitted to the areas beyond the impact point, absorbing energy, so that fragments or warheads can be wrapped in bulletproof layers.

First generation: Hardware bulletproof vest

It mainly used special steel, aluminum alloy and other metals as bulletproof materials, first appeared in World War I.

The second generation: Software Bulletproof vests

In the early 70s of last century, with the success of the development of synthetic fiber "Kevlar", the bullet proof clothing could normally resist bullets fired by pistols 5 meters away, and would not produce two shrapnel. However, they were more deformed after being hit by bullets, and were difficult to resist for rifle bullets.

The third generation: composite bulletproof vest.

It usually takes light ceramic sheet as the outer layer, and high performance fabric such as Kevlar as the inner layer, which is the main development direction of the bulletproof vest.
