Practical research on domestic carbon fiber, firm direction

As a country with a large demand for carbon fiber, China’s carbon fiber market is expanding year by year.

In the coming years, with the increase in supply and the overall improvement in the macro economy, the demand for high-grade carbon fiber in China will also maintain a relatively rapid growth. However, the backwardness of domestic carbon fiber technology has become a “stumbling block” that restricts the healthy development of China’s carbon fiber industry.

At present, the global carbon fiber core technology is firmly in the hands of a few developed countries. On the one hand, developed countries led by the United States and Japan impose strict technical standards on the Chinese carbon fiber industry; on the other hand, foreign carbon fiber industry leaders have begun to enter the Chinese market in recent years, and the pressure on China's domestic carbon fiber companies has greatly increased. Although the Chinese government has increased its guidance and support for local carbon fiber companies, under the large technological gap, the breakthrough of domestic carbon fiber companies is still awkward.

The backward technology directly leads to a significant gap between China's carbon fiber product quality and imported products, and also limits the application of domestic carbon fiber products in high-end areas. In this regard, some experts and entrepreneurs believe that China's carbon fiber companies have to break through international technology and must start with the need to increase the quality of domestic carbon fiber.

The relevant person in charge of the China Chemical Fiber Association believes that carbon fiber companies must adhere to independent research and development. As carbon fiber is a strategic basic material, it is an indispensable key material for national defense construction and advanced weapons production. Therefore, in order to develop carbon fiber, China must insist on independent research and development and take the road to localization. From the technical development of China's carbon fiber for decades, we can see that carbon fiber technology R & D production and scientific research out of touch, scientific research institutions also do not get strong financial support. If China's carbon fiber technology is to have better development, it must take the road of joint development of production, education, and research so as to better allocate social resources, achieve the joint research of production, education and research and improve the research and development capabilities of China's carbon fiber industry.

The person in charge of Shandong Xintai Technology Company believes that it is necessary to make full use of the technology and experience of traditional chemical fiber companies. Traditional chemical fiber enterprises have strong strength in the research and development of new chemical fiber products. China, as a world leader in chemical fiber, can not ignore the R&D strength of traditional chemical fiber companies. In fact, most of the international carbon fiber companies have been transformed from large chemical fiber companies. Therefore, it is very important to make breakthroughs in the field of carbon fiber by making full use of the experience and technology of traditional chemical fiber companies. In the production scale, the development of large tow carbon fiber should be the mainstay. China is still at a very low level in terms of the development of carbon fiber and raw silk. With limited R&D capabilities, it is very important to choose the research focus. Compared with the small tow carbon fiber, the large tow carbon fiber has the advantages of lower technical difficulty, lower production difficulty, lower production cost and wider application, and is more suitable for the priority research and development of carbon fiber enterprises in China.

At the same time, experts emphasized that it is necessary to reduce the current low-level redundant construction projects. Although there are nearly 40 domestic carbon fiber companies, there are currently only four hundred-ton companies with a complete production chain of raw silk and carbonization. Other companies are either small enough to have only a few tens of tons, or they have only carbonization equipment and no production facilities. The ability of silk. While foreign companies are basically all over the scale of 1,000 tons, companies like Toray of Japan and Mitsubishi Rayon have reached 10,000 tons, and they all have a complete production chain. To catch up with the level of the developed countries, our enterprises must learn from the beginning and start from scratch. We still have a long way to go.
