Interview With Professor Pan Ding, Donghua University

There is a magical fiber, only 1/10 of the hair, and the strength of the fiber bundle is 4~5 times that of the steel. In the high temperature environment above 2000 degrees, other fibers may have been turned into ashes, but it has remained motionless. Its development has not only helped the intercontinental missile to fly successfully, but now it has also created a revolution whirlwind in the field of new materials, which can be used to build large aircraft, automobiles and ships. It can significantly reduce weight and speed up, and use it to make golf clubs and badminton rackets, light and durable.

It is known as "black gold".

。

On the campus of Donghua University, there is an expert who has spent the rest of his life with carbon fiber. He is Professor Pan Ding of the school of materials science and engineering.

Tackling difficulties: helping missiles fly to the sky

With the support of the relevant state departments, Professor Pan Ding led the carbon fiber project team at risk, and finally successfully developed the aerospace grade high purity viscose based carbon fiber in Jimei and Russia.

Professor Pan Ding had been indissoluble with carbon fiber more than 40 years ago.

In 1978, he was admitted to East China Textile Institute of Technology (Donghua University predecessor).

Since then, under the guidance of Professor mentor and Professor Qian Baojun, Professor of chemical fiber in China, he has begun to concentrate on the theory and industrialization of carbon fiber.

Professor Pan recalled that in the 80s of last century, the number one strategic weapon intercontinental missile in China was faced with the last two technical problems that could not be attacked for a long time.

One of the "obstacles" is the aerospace grade high purity viscose based carbon fiber.

As the key material of the intercontinental ballistic missile warhead, the performance and quality of the aerospace grade high viscose based carbon fiber are directly related to the quality and success or failure of the missile flight.

Because of its high raw material requirements and extremely difficult preparation technology, only two superpowers, the United States and Russia, were in the process, and a tight embargo and technology blockade were imposed on China.

Difficult to attack, missiles can not last!

With the support of the relevant state departments, Professor Pan Ding led the carbon fiber project team at risk, using foreign negation, the only domestic cotton pulp cellulose as raw material, and successively conquered "

After 4 years of hard struggle, a series of breakthroughs have been made in the basic theory, technology and preparation of carbon fiber production, and a lot of original achievements have been obtained in the software and hardware technology. Finally, the aerospace grade high purity viscose based carbon fiber, which is capable of producing similar products in Jimei and Russia, has been successfully developed, providing critical technical support for strategic weapons.

Professor Pan has not only filled the gap in China, but also made China the third country in the world to master the development technology of high purity viscose based carbon fiber at the aerospace level, and contributed to the upgrading of China's defense modernization and the achievement of defending the modernization of the national economy.

Over the past 10 years, Professor Pan Ding has worked with the national strategic mission to provide continuous and stable carbon fiber products for all kinds of missiles under active service and follow-up. It has been fully affirmed by relevant Aerospace departments and military representatives, and has won many awards such as the national science and technology progress award.

Dare to take the lead: upgrading the industry

If the viscose based carbon fiber is "born out of the world", it shows Donghua University.

In the field of research, the courage and courage of "dare to be first", then the continuous tackling of PAN based carbon fiber reflects the determination and perseverance of the team led by Professor Pan in striving for excellence in the process of upgrading the new material industry.

Compared with viscose based carbon fiber, PAN based carbon fiber is also used for national defense industry, but its civil field is more extensive, not only for aircraft, automobiles and other pportation tools, but also for building materials, medical equipment, sports goods and so on.

For aircraft, the aluminum alloy consumables were used before, with fatigue limits. Instead of PAN based carbon fiber materials, not only the fuselage is lighter, but also faster, and more importantly, the strength is strengthened, the fracture probability is greatly reduced, the safety factor has also been greatly improved, and energy efficiency and environmental pollution have also created outstanding benefits.

At present, China's largest civilian carbon fiber production enterprise is located in Lianyungang, Jiangsu, Eagle swim group Zhongfu divine eagle Carbon Fiber Co., Ltd.

The company has created a number of "first" domestic carbon fiber fields: the first to achieve 1000 tons of T300 carbon fiber industrial production, the first to achieve dry spray wet spinning T700 carbon fiber technology breakthrough, in 2011 the national carbon fiber output nearly 1500 tons, the eagle's carbon fiber sales have reached 1000 tons.

Behind these auras, Professor Pan Ding led the scientific research team of Donghua University to help the eagle tour group.

Zhang Guoliang, chairman of the company, was deeply touched by this.

In 2005, Zhongfu divine eagle company just started. Zhang Guoliang visited almost all of China's carbon fiber research experts, because technology is difficult to achieve industrialization, and only a few experts such as pan Ding support him.

Zhang Guoliang also clearly remembered that from September 29th to October 2nd of that year, Professor Pan had systematically developed the first carbon fiber lesson for himself and his team in the textile machinery manufacturing industry for 5 days. From acrylonitrile monomer to carbon fiber strands of graphite structure, Professor Pan's deep and detailed introduction from the raw silk, carbonization production line to the development of carbon fiber composites such as airplanes, missiles, automobiles, bicycles, and so on, has aroused the interest of Zhang Guoliang and business personnel in carbon fiber.

The close cooperation and collaborative innovation between schools and enterprises started from this point of view and "no gains".

Under the guidance of Professor Pan Ding, the research team of the school of materials, Donghua University, relies on the advantages of the national key disciplines of materials science, the ten major national key research projects such as the most important subjects in Shanghai and the National Key Laboratory of fiber material modification. It will introduce the theory of "the production and elimination of defects in the whole process" in a series of major theoretical research projects such as 973 and other provinces and cities, and introduce the key unit and integration technology of high performance carbon fiber manufacturing at home and abroad. In a number of Jiangsu achievements pformation projects, it will jointly declare and undertake scientific research tasks, providing a strong scientific and technological support for the general purpose industrialization of high carbon fiber and the manufacture of high strength and high modulus carbon fiber.

Since 2009, Donghua University, Zhongfu Eagle carbon fiber engineering and technology center, Donghua University Zhongfu Eagle Eagle Carbon Fiber Engineering Research Center, Donghua University material science and engineering post doctoral mobile station research base, and Eagle tourism group carbon fiber post doctoral research station research base have been established, enhancing the R & D strength of enterprises, and providing solid guarantee for the industrialization process of carbon fiber.

Speaking of future development, Zhang Guoliang said with confidence: "nowadays, we have realized the self design, self manufacture, self installation and self commissioning of carbon fiber series production equipment and multiple production lines, basically breaking the close blockade of key production technologies and equipment by foreign advanced countries, and the construction of 10000 tons of carbon fiber production base already has the scale.

It is estimated that by 2015, the domestic production demand of carbon fiber will reach 12 thousand tons. As soon as possible, we will soon change the backward situation of carbon fiber production in China, catch up with and surpass the advanced level of the world.

With the strong cooperation and close cooperation with Donghua University, we have confidence and ability to boost the dream of industrialization of China's carbon fiber.

Persist in exploration and strive for the country and the people

Professor Pan Ding said: "the rise and fall of the nation is the responsibility of all. Research should solve key technologies and serve the national economy and the people's livelihood. This is the source of strength that supports me and my colleagues today."

Counting from his involvement in the carbon fiber business, Professor Pan Ding, a very ancient Professor, has been dealing with the "black leader" of the fiber industry for nearly half a century.

In order to develop the urgently needed carbon fiber products at an early date, he and the teachers of the project team often rushed to the production line all night, regardless of the heat and cold weather, and no fear of hardship, they made the workshop a home, and lay down on the steel platform for a while, and then they ate something when they were hungry.

Professor Pan said frankly that in the study, there had been too much pressure to be breathless. The pressure was so large that it could hardly bear, but finally it came through with persistent belief.

"The rise and fall of the nation is the responsibility of all the people. To do research, we should solve the key technologies and serve the national economy and the people's livelihood. This is probably the source of strength that supports me and my colleagues today."

During the interview, the reporters also learned that Professor Pan had paid attention to the innovation of technology and technology, and the collaborative innovation with the enterprises, and paid attention to basic research in the study of carbon fiber.

Like Professor Pan, he is also the chief scientist of the national "973" project and Professor Yu Muhuo, deputy director of the State Key Laboratory of fiber modification, Donghua University. He is currently responsible for the national key basic research project of "key scientific issues in the preparation of high performance aramid fiber".

According to him, Donghua University has achieved success not only in the localization and stable production of viscose based carbon fiber and PAN based carbon fiber, but also in the theoretical research field of high performance ceramic fibers, ultra-high strength organic high-performance fibers and other new high-performance fibers.

"The vision of high-performance fiber research must be long-term, understand the national development strategy and its needs, accurately grasp the international development trend; while solving theoretical problems and key technologies, we must consider whether industrialization can be done and serve the enterprises wholeheartedly, so that we can do something."
