The development of China's carbon fiber industry is difficult

Carbon fiber is an inorganic polymer fiber with a carbon content of more than 90%. It is generally used as a reinforcing material added to resins, metals, ceramics, etc. to form a high strength, high modulus, light weight, fatigue resistance, corrosion resistance, etc. A new series of excellent performance composite materials.

In general, high-standard medical equipment is highly concerned with the quality, hygiene, reliability, and precision of the raw materials used. The medical equipment made of carbon fiber material has the characteristics of light weight, high stability, high strength, and resistance to breakage.

For example, carbon fiber materials can be used in sandwich structural components such as X-ray mesas, booms, and head restraints made of special carrier foams. Patient supporters using such components can withstand loads up to 1200kg, while conventional supporters can only withstand 400kg.

At present, the carbon fiber industry has been incorporated into the important development direction of strategic emerging industries. However, in the current critical period of upgrading industrial technology and expanding market scale, the development of China's carbon fiber industry faces numerous obstacles.

According to Duan Xiaohua, an associate researcher at the Institute of Industrial Science and Technology Development of the China Academy of Science and Technology Development, a large amount of pre-phase carbon fiber production enterprises in foreign countries have already received huge returns in global market sales, and will soon be eliminated after entering the product upgrading period. The specification products are sold to China at a low price to achieve the purpose of curbing the technological progress of Chinese enterprises. This is one of the problems facing the carbon fiber industry in China.

At present, 95% of the global carbon fiber market has been occupied by large foreign companies. Compared with foreign countries, the domestic carbon fiber industry is still in the "naive period." There are no more than six domestically produced silk producers, and none have formed a scale. 90% of the original silk still needs to be imported, and domestically produced carbon fiber is also concentrated in general, basic and low-grade varieties.

Duan Xiaohua believes that based on China's current level of research and development, carbon fiber production costs at least 200 yuan / kg, while the Japanese company's carbon fiber market sales price of 160 to 170 yuan / kg, not long ago, Turkish companies in the short term to produce more carbon fiber The price of 110 yuan / kg thrown to the Chinese market, a great impact on domestic companies.

“Foreign companies adopting this low-price competitive marketing strategy in response to the characteristics of the Chinese market will force domestic downstream carbon fiber products companies to continue importing large quantities of them, which makes raw silk production enterprises with low domestic technology levels more difficult to obtain in market development. Technical learning opportunities." Duan Xiaohua said.

In addition, under a good market expectation, domestic carbon fiber companies still have a large number of low-level repeated investment. Only Dalian Xingke Carbon Fiber Co., Ltd. built four carbon fiber bases with an annual output of 10,000 tons in Dalian, Baotou, Sanhe and Baoding respectively. In addition to private enterprises, China PetroChina, Sinopec, China Chemical Industry, China Steel, China National Building Materials, China Hengtian, Shougang International and other large state-owned enterprises have also adopted "big" intervention. The production capacity of these enterprises' investment will greatly exceed the actual demand and will also face a difficult situation.

Duan Xiaohua said that the carbon fiber industry involves a relatively long industrial chain, and scientific research institutions and related companies should form a reasonable division of labor. However, with promising market prospects, carbon fiber producers need to be closed to each other out of market competition, which is particularly serious, which further delays the process of industrial technology upgrading.

“At present, a large number of companies have invested heavily in the production phase to expand their production scale, and some basic research is lacking. For example, oil-reinforced carbon fiber products have not been developed in China,” Duan Xiaohua said.
