According to Hong Kong media, a research team at Tsinghua University in China said they have developed a high-strength fiber that can even be used to make an elevator to space. According to the Hong Kong South China Morning Post website reported on October 26, they said that only 1 cubic centimeter of fiber made of carbon nanotubes can withstand the weight of 160 elephants (over 800 tons) without breaking. The small cable weighs only 1.6 grams. Wang Changqing, a scientist at the School of Automation of Northwestern Polytechnical University who did not participate in the study, said: "This is a major breakthrough." It is reported that the team used carbon nanotubes to develop a new type of "ultra-long" fiber, and said that the strength of this fiber is higher than any previous fiber. They obtained the patent right for this technology earlier this year, and published part of their research results in the British magazine "Natural Nanotechnology". The team stated in the paper: "Obviously, the tensile strength of carbon nanotube bundles is at least 9 to 45 times that of other materials." They said that this material "is in great demand in many high-end areas, such as sports equipment, ballistic armor, aerospace and even space elevators." It is reported that the idea of ​​making an elevator that can enter space from the earth may sound like something in science fiction, but it has existed for more than a century, and scientists have proposed various design solutions in recent decades. So far, the concept of space elevators has stayed in the field of physical and mathematical models, because there is no high enough material to make the ultra-light and super-strong cables needed. The National Aeronautics and Space Administration (NASA) said the tensile strength of these cables needs to be no less than 7 gigapascals. In fact, NASA launched a global competition to develop this material in 2005, with a bonus of $ 2 million. But no one received the prize. Now, the Tsinghua University team headed by Professor Wei Fei of the Department of Chemical Engineering said that the tensile strength of their newly developed carbon nanotube fibers reached 80 gigapascals. According to reports, carbon nanotubes are cylindrical molecules composed of carbon atoms. These carbon atoms are connected into a hexagon and have a diameter of only 1 nanometer. Its tensile strength is the highest of any material known, theoretically up to 300 gigapascals. Wang Changqing said that in terms of manufacturing space elevator cables, it seems that carbon nanotube fiber is the most promising candidate material, but more calculations and simulations are needed to evaluate its performance. Wei Fei said that although it may take many years to build an elevator that leads to space, his team is working hard to put this carbon nanotube fiber into mass production for defense or other fields. He said, "This may change the rules of the game in many areas", the technology may be used first for military purposes. He said: "Many new weapon systems such as magnetic guns and laser guns require high-performance power storage and supply systems, and our technology provides a more appropriate solution." It is reported that these researchers made the world's longest (50 cm) carbon nanotubes in 2013, and recently made a 70 cm long carbon nanotube.
