Chapter 254 T10001
Wu Tong currently has extremely high authority, and the confidential database has been opened to her, allowing her to access the information she needs. If she needs additional information, she can also ask for it to be collected by professional data clerks.
Wu Tong was looking up information about the carbon fiber sector. In 1975, under the adverse circumstances of severe international atmosphere and strict technological blockade in China, the technical pioneers at that time had already made certain technological breakthroughs and completed a major step from nothing to something.
However, with the reform and opening up, the domestic trend has been to look outward, and many people have blindly worshipped Western technology. Under the impact of mature products from the opposite side, it can be said that there has been no new progress in the domestic carbon fiber field for more than 20 years.
Later, the country realized this and was working hard to make changes.
Since 2000, at the beginning of the new century, domestic carbon fiber technology has begun to shift towards diversified technological development, abandoning the original nitric acid method of raw fiber manufacturing technology.
Scientific researchers have achieved success using a one-step wet spinning technology using dimethyl sulfoxide as solvent, and a few domestically produced T700 carbon fiber products developed using independent technology have gradually reached the level of similar international products.
However, what comes with it is the increasing demand for domestic carbon fiber, and carbon fiber has been listed as a key support for the national chemical fiber industry. In 2005, the global carbon fiber market was only US$900 million, but it is expected to reach US$10 billion in 2013. Ten years later, after 2023, it is expected to reach US$40 billion. The application of carbon fiber composite materials will also enter a new era.
The industrialization of carbon fiber has adopted a path that combines independent development and introduction. Only now has the domestic carbon fiber scale production line equivalent to the T300 of our neighbor been basically realized. Only a very small number of companies have formed a 100-ton production line above the T700 level.
It is a technological innovation, which is not so easy. If the T700 carbon fiber material can meet the needs of ordinary domestic business or some non-key needs, but if it is to be used in fighter jets and if the fighter jets want to achieve higher maneuverability, the performance of carbon fiber materials must be improved. The current T700 and the 3K process are not enough.
The diameter of a single carbon fiber is extremely fine, less than 5 microns, which is equivalent to one-tenth to one-fiftieth of a hair, but its strength is more than 4 times that of aluminum alloy and 7-9 times that of steel.
The world already has more advanced T800, 12K, 24K, and even 48K technologies, and there is still much room for improvement in domestic technology and production equipment.
Wu Tong studied and researched quickly, absorbing the specially retrieved information in the field of carbon fiber, quickly understanding and mastering it, and recording the sparks of inspiration that occurred during her research when new knowledge collided with old reserves.
After Wu Tong had sorted out the current foundation of the entire carbon fiber sector, the new research direction was presented to her more smoothly than she expected. Wu Tong naturally did not hesitate, grasping this dawn of inspiration, and began to deduce and formulate the general direction.
With a clear direction as a basis and his mathematical skills improved, Wu Tong established a mathematical model with greater ease. Thanks to the thoroughness of the mathematical model, the details of the new carbon fiber manufacturing and the composite materials with it were gradually filled in and tended towards perfection.
Wu Tong did not seek simplicity, but directly innovated the T700 process. This can quickly make certain breakthroughs, but it also has corresponding limitations. In order to get a material with better performance in a short time, Wu Tong still took the trouble to start from the most basic composition of carbon fiber.
Carbon fiber is mainly composed of carbon elements. Wu Tong improved the microstructure of carbon fiber at the nanoscale, redefined the preferential orientation of its graphite microcrystal structure along the fiber axis, the crystallite size, and the strength and modulus along the fiber axis, and enhanced the tensile curve of carbon fiber monofilament. This is a symbol of the technological breakthrough from short fibers to long fibers and the basis for the production of high-energy fibers.
High-energy fibers, which can withstand high temperatures and have high physical stability, are the basis for the formation of composite materials.

When inspiration comes, it is crucial to seize the opportunity to break through. Wu Tong sent a message to her family, saying that she had some inspiration and would stay at school to study the topic in seclusion for a while. An Wenshu would help her and her family to explain the specific situation. She re-opened the dormitory on campus and in her own space, she went all out to start absolute deduction and carry out comprehensive and comprehensive research and development.
After his family moved to Beijing, Wu Tong had been going home recently, going back and forth between school and home. He had not used the school dormitory for some time. However, the logistics department did not take it lightly. Someone would take care of it regularly and replace spare items to prevent Wu Tong's sudden needs at this moment.
The school would not cancel Wu Tong's dormitory living rights just because he was going home recently. If they were not afraid of being too conspicuous, they would double their support for Wu Tong. After all, the cost of inviting a top international scholar like Wu Tong is much higher than the cost of Wu Tong, who is not too concerned about the conditions and is a real child of his family.
After the design of high-energy carbon fiber materials, Wu Tong further deduced the best combination of carbon fiber composite materials, epoxy resin, and on this basis deduced strong epoxy resin materials, and then defined their optimal combination ratio, thereby achieving superior improvement in specific strength and specific modulus performance, as well as super fiber plying technology...
One difficulty after another was overcome under Wu Tong's deduction, and the material was named T10001 by Wu Tong, and finally a super carbon fiber composite material with a mass of up to 48K was born. This super composite carbon fiber material is expected to have excellent mechanical properties, with tensile strength, tensile modulus, bulk density, linear density, etc., which are double the strength of the current domestic T700 material, and are even ahead of various performance parameters of the international T800.
Logically speaking, Wu Tong should be happy that he had once again deduced a breakthrough super material. However, when he deduced this ultra-high-strength material, Wu Tong felt a headache besides being happy!
Absolutely high-performance materials also represent absolutely high requirements for processing technology. The current level of domestic production equipment cannot meet the technology for processing T10001. For small-scale laboratory preparation, the preparation equipment must also be improved.
Moving from experimental materials to large-scale production on production lines will also be a major hurdle that needs to be overcome.
Only by forming a large-scale production line with tons as units can they be put into fighter planes and spacecraft for large-scale use. The vertical take-off and landing fighter she is looking forward to will be the premise for the next step of research and development.
The usage of these big guys is extraordinary, and if you want to supply enough of them, you need mature technology.
