Before returning to the college entrance examination, I became popular in the science circle

Chapter 255 T10001
Wu Tong's current authority is extremely high, and the confidential database has been opened to her so that she can check the information she needs. If she needs additional information, she can also ask her to go out and have a professional data person help her collect and compile it.

Wu Tong looked up the information on the carbon fiber sector. In the 75s in China, under the severe international atmosphere and strict technology blockade, the technical sages at that time had already made certain technological breakthroughs and completed the process from scratch. Some major steps forward.

However, with the reform and opening up, the domestic atmosphere advocates outwardness, and many people blindly worship 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 [-] years.

Later, the country realized this and was working hard to make changes.

Since 2000, the beginning of the new century, domestic carbon fiber technology has begun to shift to technological diversification, abandoning the original nitric acid raw fiber manufacturing technology.

Scientific researchers have succeeded in using one-step wet spinning technology using dimethyl sulfoxide as the solvent. A few domestic T700 carbon fiber products developed using independent technology have gradually reached the level of similar international products.

But what follows is the growing domestic demand for 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$9 million, but it is expected to reach US$2013 billion in 100. Ten years later, it is expected to reach US$2023 billion after 400. The application of carbon fiber composite materials will also enter a new era.

The industrialization of carbon fiber adopts the path of combining independent development and introduction. Only now has a domestic carbon fiber large-scale production line equivalent to the T300 in the small days next door has been basically realized. Only a few companies have formed a 700-ton production line above the T[-] level.

It's a technological innovation, it's not that easy.If the T700 carbon fiber material can meet the needs of ordinary domestic business or some non-key needs, but if you want to fly on a fighter plane and want the fighter plane to achieve higher maneuverability, the performance of the carbon fiber material will need to be improved to a higher level. The current T700 and just now 3K craftsmanship seems to be not enough.

The diameter of a single carbon fiber is ultra-fine, less than 5 microns, which is equivalent to one-tenth to one-fiftieth of a hair. However, its strength is more than 4 times that of aluminum alloy and 7-9 times that of steel.

There are already more advanced T800, 12K, 24K, and even 48K technologies in the world. There is still room for great progress in domestic technology and production equipment.

Wu Tong quickly studied and researched, absorbing the specially obtained information in the field of carbon fiber, quickly understanding and mastering it, and recording the sparks of inspiration generated by the collision of new knowledge with old reserves during her research process.

After Wu Tong had completely sorted out the current foundation of the entire carbon fiber sector, new research directions were presented to her more smoothly than she expected.Wu Tong naturally did not hesitate. He grabbed this glimmer of inspiration and began to deduce and draw up the general direction.

With a clear general direction as a basis, Wu Tong established a mathematical model with greater ease after improving his mathematical skills. Relying on the thoroughness of the mathematical model, the manufacturing of new carbon fiber, and the details of composite materials, Gradually it is filled and tends to be complete.

Wu Tong did not seek simplicity and directly innovated on the T700's technology. This could quickly make certain breakthroughs, but it also had corresponding limitations.Wanting to obtain materials with better performance, 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 has improved the microstructure of carbon fiber at the nanoscale, redefined its graphite crystallite structure with preferred orientation along the fiber axis, crystallite size, and strength and modulus along the fiber axis, enhancing The stretchable curve of carbon fiber monofilament is a symbol of the technological breakthrough from short fiber to long fiber and the basis for the production of high-energy fiber.

High-energy fibers, which can withstand high temperatures and have high physical stability, are the basis for composite materials.

·····
When inspiration comes, seizing the opportunity to break through is the key.Wu Tong sent a message to her family and got some inspiration. She will be studying the topic in retreat at school in the near future. An Wenshu will help her explain the specific situation to her family. She has re-activated the on-campus dormitory, which belongs to her alone. Within the space, go all out to launch absolute derivation and carry out comprehensive and complete research and development.

After his family moved to Beijing, Wu Tong has been going home most of the time, maintaining a close relationship between school and home. The school dormitory has not been used for some days.However, the logistics department did not hesitate because of this. Someone would take care of it regularly and replace spare items to prevent Wu Tong's sudden needs at this moment.

The school will not cancel Wu Tong's right to live in the dormitory because Wu Tong went home recently.If they were not afraid of being too conspicuous, they would not hesitate to double their support for Wu Tong.After all, the price of inviting a top international scholar like Wu Tong is much higher than the price charged by Wu Tong, a child of his own who doesn't care much about conditions and is just a real person.

After the high-energy carbon fiber material was designed, Wu Tong further deduced the best combination of carbon fiber composite materials, epoxy resin, on this basis, deduced the strong oxygen resin material, and then defined their optimal combination ratio, and then Achieve superior improvement in specific strength and specific modulus performance, as well as super fiber plying technology...

Each difficulty was overcome with Wu Tong's deductions, and was named T10001 by Wu Tong. Finally, the super carbon fiber composite material with a height of 48K was born.This super composite carbon fiber material is expected to have excellent mechanical properties. Tensile strength, tensile modulus, bulk density, linear density... are all twice as strong as the current domestic T700 materials, and are even ahead of various international T800 materials. Performance parameters.

It stands to reason that Wu Tong should be happy that a leap-forward super material has been deduced once again. However, Wu Tong is not only happy but also has a headache when such an ultra-high-strength material is deduced!
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. Small-scale laboratory preparation also requires improvement of preparation instruments.

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 measured in tons can they be able to board fighter planes and spacecraft for mass use.What she is looking forward to is a vertical take-off and landing fighter aircraft, which is the prerequisite for the next step of research and development.

The usage of these big guys is extraordinary. If you want to supply enough usage, it cannot be achieved by non-mature technology.
