The free breaking length of ultra-high strength polyethylene fiber in water is infinite. Under the same thickness, the maximum quality it can withstand is 8 times that of steel wire rope. It is the third generation of ultra-high strength after carbon fiber and aramid fiber. Intensive fiber has an irreplaceable role in the military industry and aerospace industry. Its most important function is bullet-proof and stab-resistant. The quality of body armor made of it is much lighter than traditional body armor and its strength is high. Since 2002, China has applied this ultra-high strength fiber to the recovery system of the "Shenzhou" spacecraft and achieved good results.
It is understood that Donghua University's research group for the ultra-high strength polyethylene fiber industry has conducted research on jelly spinning technology simultaneously with the world. In 1985, the research group began to study basic theory, gradually cracked down on a series of technical problems such as jelly spinning technology, extraction technology and extraction equipment, and nanoparticle use technology. It has obtained 6 invention patents in some key technical fields. Walking in the forefront of the world.
I become one of the top three global super strength polyethylene fibers
Ultra-high-strength polyethylene fibers used to have only two countries, the Netherlands and the United States, with their own independent intellectual property rights. The global annual output is only 8,000 tons, which is a scarce material in the world. China is now the third country to produce, with an annual output of 1,000 tons. This scientific research achievement developed by Donghua University’s Chemical Fiber Research Institute won the first prize of Shanghai’s Science and Technology Progress Award this year.
