< p > < strong > the concept of process control ability is weak, and the concept of stability is less than /strong > < /p >.

Question 1: Question 1: at present, China has not only realized the industrialization of high-strength carbon fiber varieties, but also the stability and reliability of low-end T300 carbon fiber products are still far from foreign countries. What do you think is the crux of the problem? < /p > p

< p > Xu Lianghua, director of the National Center for carbon fiber engineering and technology, Beijing University of Chemical Technology: Although the T300 grade carbon fiber has been established in China, the stability and reliability of the products still need to be further improved.

The idea of product stability in Chinese enterprises deviates intentionally or unintentionally. In fact, the stability of product quality in production process can not be equal to the batch stability of products supplied to users.

The quality of products of different batches is quite different, and it will also affect users.

< /p >

The engineering construction of domestic carbon fiber produced by P technology has led to the weak capability of independent research and development of carbon fiber in China.

The main technology of the two methyl sulfoxide precursor has not been substantially improved and upgraded over the past 10 years. The same process gene has led to common problems in the technology and quality of domestic carbon fiber.

On the other hand, due to the lack of deep research on technology, the design guidance for localization equipment is relatively weak, the coordination level of equipment and technology is low, resulting in low capacity release capability, high energy consumption, poor operation stability and short life cycle.

The relatively backward equipment technology also leads to poor product performance stability, high production cost and the overall competitive advantage of the industry.

< /p >

< p > Zhu Bo, director of the carbon fiber composites research and development center of Shandong University: China's carbon fiber process and process control are not stable enough, so the product stability control is very difficult.

Integration of process and equipment should be realized to ensure product quality stability.

< /p >

< p > < strong > cost reduction depends on upgrading of technology and equipment < /strong > /p >

Question P: Two: high cost is another main problem that hinders the application of domestic carbon fiber in downstream. What link do you think is the key to reduce cost? < /p >

< p > Xu Lianghua, director of the National Center for carbon fiber engineering and technology research, Beijing University of Chemical Technology, said: carbon fiber production enterprises should develop new technological pformation and build production lines, carry out the two integrated innovation of traditional technologies, achieve the goal of upgrading technology, stabilizing product quality and improving economic efficiency by optimizing technology, upgrading equipment and reducing energy consumption.

< /p >

< p > Zhu Bo, director of the carbon fiber composites research and development center of Shandong University, China: the high cost of carbon fiber production in China is mainly due to the lack of innovation in the technology of carbon fiber equipment, the high investment in imported equipment, the high energy consumption and the low utilization ratio of energy in the production process, and the vicious contradiction between the contradiction between the cost of production and the scale of production.

Therefore, in order to reduce costs, we should promote the upgrading of domestic equipment technology, realize equipment localization and reduce investment.

The carbon fiber production line should be systematically planned and designed, increasing investment in science and technology, improving the comprehensive utilization rate of energy and reducing the running cost.

Research and develop new processes to improve product quality and yield.

< /p >

< p > Zhang Guoliang, chairman of Zhongfu divine eagle Carbon Fiber Co., Ltd.: to reduce production costs, one solution is to reduce the cost of raw silk production and develop new carbon fiber precursors, improve the production process of raw silk, and explore the use of other materials outside PAN to prepare high performance carbon fiber precursors. By improving the polymerization monomer and polymerization technology, the precursor with the same structure as pre oxidized fiber can be formed at the polymerization stage.

In addition, new pre oxidation, carbonization and graphitization technologies should be developed to develop new pre oxidation technologies, shorten the pre oxidation time, reduce the cost of carbonization and graphitization, develop microwave technology, and independently develop energy-saving and efficient carbonization equipment.

< /p >

< p > Yu Muhuo, vice president of Research Institute of Donghua University: the development goal of low cost technology of carbon fiber is to reduce the production cost per kilogram to 5~8 US dollars.

In the cost structure of carbon fiber, 50% of raw silk and 50% of oxidation and carbonization.

At present, the low cost technology of carbon fiber mainly includes large tow, aqueous precipitation polymerization, dry jet wet spinning process, and production of carbon fiber technology by civil acrylic fiber engineering.

The new technology of low cost carbon fiber precursor is made from lignin raw material, lignin PAN blend precursor, carbon fiber and lignin precursor prepared by melt spinning, high viscosity PAN solution dry spray wet spinning and so on.

In the low cost of oxidation and carbonization, the technology of rapid oxidation and carbonization (dispersing or decreasing the heat of cyclization) is used to increase the oxidation rate and improve the utilization rate of energy.

< p > < strong > the combination of market promotion and upstream and downstream should not be less than < /strong > /p >

Question three: question: the downstream application of carbon fiber is broad, but domestic carbon fiber is just beginning in many ways. How should we develop the market and promote products? < /p > p

< p > Song Lianhua, deputy general manager of Strategic Project Development Department of Jiangsu Heng Shen fiber material Co., Ltd.: we are going through the long-term research and summarizing the development experience of excellent enterprises.

They have the following advantages: first, the scale of development, so that the cost is also reduced and competitive.

The two is to build a complete industrial chain.

The three is to develop the carbon fiber industry. At the same time, the corresponding industries should be developed synchronously and synchronously.

For example, the development of sizing agents, resins and so on should also keep pace with them.

< /p >

< p > Zhu Bo, director of the carbon fiber composites research and development center of Shandong University, should be steady and steady, do well in the seamless connection between technology research and development and production and application, increase the series development of composite products, solve the key problems in the preparation of composite products, and make good use of all kinds of carbon fibers to drive the upstream development.

< /p >

< p > Zhang Dingjin, chairman of China Composite Material Group Corporation: Although there are still many technical problems in the large-scale use of carbon fiber in the automotive industry, carbon fiber has broad application prospects in the automotive field.

Constantly improving manufacturing technology, getting through the technical barriers from raw materials to processing, and achieving the best performance at the lowest cost is the goal of our efforts.

To achieve breakthroughs in automotive applications, China's carbon fiber production enterprises must also focus on cooperation with resin suppliers, intermediate product manufacturers and equipment manufacturers.

< /p >

< p > Fang Da Jiang City enterprise representative: the enterprises in the carbon fiber industry chain should strengthen cooperation and maintain an open mind and not be closed.

On the one hand, the government should continue its original financial support, and on the other hand, it should increase its support in application.

< /p >

< p > < strong > industry chain must be integrated development < /strong > < /p >.

Question P: question four: the development of carbon fiber involves many links. How do you think that the strength and advantages can be gathered to achieve breakthroughs and improvements in the industry? < /p >

< p > Song Lianhua, deputy general manager of Strategic Project Development Department of Jiangsu Heng Shen fiber material Co., Ltd.: the development of Jiangsu Heng Shen T300 grade carbon fiber has been strongly supported by the state, the association and the local authorities. At present, the relevant certification of aircraft application has been passed.

T700 grade carbon fiber has passed the certification of the NDRC, and T800 grade products have not been produced in large scale, but they have been continuously produced.

< /p >

< p > Jiangsu Heng Shen insists on the development mode of industry, University and Research Institute. Instead of implementing this mode in a project, the company integrates this pattern into long-term work.

Industry university research is the way of business.

< /p >

< p > Jiangsu Heng Shen is one of the early domestic enterprises entering the field of carbon fiber, and has accumulated rich experience in the development of carbon fiber.

At present, the development of carbon fiber has several characteristics: first, there are few enterprises in China that achieve large-scale, stable and high-quality production.

Two, it is believed that the prospect of carbon fiber is good. Many enterprises are coming in. The phenomenon of low level repetitive construction is widespread, resulting in fierce competition in the industry.

Three, there is much room for improvement in reducing costs, improving quality and enriching product categories.

< /p >

< p > as the saying goes, a clever woman can't make bricks without straw.

China's < a href= "http://www.91se91.com/news/index_s.asp" > carbon fiber < /a > development is "no rice" at the beginning of development. But now that it has developed a certain industrial foundation, it can not help but ask where the "clever woman" is, which involves the problem of industrial personnel training.

The state should strengthen the training of talents in higher education, and education should keep pace with the development of the industry.

In particular, at present, the work of designing carbon fiber composites is very important, but there is no relevant design professionals.

From the carbon fiber to the carbon fiber composite, and then to the design and application of carbon fiber composite materials, the three links are lack of corresponding professional talents.

< /p >

< p > another important problem is that the application of CFRP must be integrated.

From the research and production of carbon fiber to the final application, there must be continuous investment and cooperation.

At the same time, we need high-quality talents who can link up the industry.

< /p >

< p >, therefore, there are several suggestions for the development of China's carbon fiber industry: first, the state must first solve the problem of talent development.

Enterprises can cultivate relevant talents through R & D production line, and the state should also cultivate relevant talents in all links of the carbon fiber industrial chain through scientific research institutes.

Especially in terms of design talent, our country is too short.

Two, all kinds of forces in the industrial chain should be jointly innovating.

We should take enterprise as the carrier to carry out system innovation.

When the industry chain is not mature, carbon fiber enterprises will be more familiar with products, and then they will make great progress in joint colleges and research institutes.

Three, the state should provide support for the carbon fiber industry as always, while attaching importance to the construction of applied demonstration projects, and moving to the project relying on application.

In the fields of rail pit, spaceflight and navigation, the state can focus on promoting the construction of a number of demonstration applications.

< /p >

At present, the polarization of the carbon fiber industry in China is obvious. "P"

Some enterprises have highlighted the tight encirclement, found their own development mode, explored and accumulated certain experience of development, some have already started to make profits, while others are still struggling, and feel no hope in the low level competition of homogenization.

This shows that the development of the industry has made great progress.

< /p >

< p > < a href= > http://www.91se91.com/news/index_c.asp > > Jilin chemical fiber > /a > Group Chairman Song Dewu: there are several points in summarizing the development experience: first, we must take the development route of the industrial chain integration; the two is the most important issue of the carbon fiber homogenization; the three is to catch the development trend of the light weight of the steam car; four, the government should encourage the application, this is more meaningful than anything, so that the market can "live" itself.
