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 order it out and a professional data clerk will help her collect it.
Wu Tong was looking up information on the carbon fiber sector. In 1976, despite the severe international atmosphere and tight technological blockade in China, the technical pioneers at that time had already made certain technological breakthroughs, completing a major step from nothing to something.
However, with the reform and opening up, the domestic trend has been outward-looking, 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 technological diversification and abandoned the original nitric acid method of raw fiber manufacturing technology.
Scientific researchers have achieved success by using a one-step wet spinning technology using dimethyl sulfoxide as solvent. A few domestically produced T700 carbon fiber products developed using independent technology have gradually reached the level of similar international products.
However, this has been accompanied by a growing domestic demand for carbon fiber, which has been listed as a key support area 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 by 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 adopts a path that combines independent development and introduction. Only now has it basically achieved a domestic carbon fiber scale production line equivalent to the T300 of the neighboring small country. Only a very small number of companies have formed a 100-ton production line above the level of T700.
This is a technological innovation, and it's not easy. While the T700 carbon fiber material can meet ordinary domestic commercial or non-critical needs, if it's to be used on fighter jets and achieve higher maneuverability, the performance of the carbon fiber material must be taken to a higher level. The current T700 and the 3K process are clearly 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 human hair. However, 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 when new knowledge collided with old reserves during her research.
Once Wu Tong had thoroughly sorted out the fundamentals of the entire carbon fiber sector, a new research direction emerged more smoothly than she had anticipated. Without hesitation, Wu Tong seized this glimmer of inspiration and began to deduce and formulate a general direction.
With a clear direction as a basis, and after his mathematical skills were further improved, Wu Tong established a mathematical model with greater ease. Thanks to the meticulousness of the mathematical model, the details of the new carbon fiber manufacturing and the composite materials with it were gradually filled in and tended to be perfect.
Wu Tong didn't seek simplicity, simply innovating on the T700 process. This approach can quickly lead to certain breakthroughs, but it also has corresponding limitations. To achieve a material with better performance immediately, Wu Tong took the trouble to start from the most fundamental components 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, as well as 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 strikes, seizing the opportunity for a breakthrough is key. Wu Tong sent a message home, announcing that she'd had some inspiration and would be spending some time at school working on a research project. An Wenshu would brief her family on the details. She'd re-opened her on-campus dormitory, and in her own private space, she was devoting herself to absolute deduction, pursuing comprehensive and comprehensive research and development.
After his family relocated to Beijing, Wu Tong had been spending most of his time at home, commuting between school and home. He hadn't used the school dormitory in a while. However, the logistics department wasn't shy about it; someone regularly took care of it, replacing spare items just in case Wu Tong needed them.
The school certainly wouldn't revoke Wu Tong's dormitory residency rights just because he was going home. If it weren't for the fear of being conspicuous, they would have doubled their support for Wu Tong. After all, the cost of inviting a top international scholar like Wu Tong is much higher than the price demanded by Wu Tong, who doesn't care about conditions and is a genuine family member.
After designing the high-energy carbon fiber material, Wu Tong further deduced the best combination of carbon fiber composite materials, epoxy resin, and on this basis deduced the strong epoxy resin material, and then defined their optimal combination ratio, thereby achieving superior improvements in specific strength and specific modulus performance, as well as super fiber plying technology...
Wu Tong's deductions eventually overcame each obstacle, resulting in the creation of a super-high-performance carbon fiber composite material, dubbed "T." This super-high-performance carbon fiber composite material is expected to have exceptional mechanical properties, with tensile strength, tensile modulus, bulk density, and linear density all exceeding those of the current domestic T700 material, and surpassing even the international T800 in various performance parameters.
Logically speaking, Wu Tong should be happy that he had deduced another groundbreaking super material, but 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 of processing T. Small-scale laboratory preparation also requires improvements to the preparation equipment.
Moving from experimental materials to large-scale production on production lines will also be a major hurdle that needs to be overcome.
Only by establishing a large-scale production line measuring tons would they be able to be deployed on fighter jets and spacecraft for mass use. This would provide the prerequisite for the next stage of research and development of the vertical take-off and landing fighter aircraft she was looking forward to.
The usage of these big guys is extraordinary, and it is impossible to supply enough of them without mature technology.
