The Development Status Of Carbon Fiber Industry Depends On The Application End To Open The New Version.

Less than P, driven by demand growth, the development of domestic carbon fiber has accelerated in recent years and production capacity has been greatly improved.

At present, more than 30 enterprises in China have been engaged in R & D and production of carbon fiber, and their capacity has exceeded 20 thousand tons.

But most of them are relatively low quality products, and the gap is obvious compared with that of foreign countries.

Therefore, the expansion of this capacity has also increased the structural surplus of carbon fiber to a certain extent.

< /p >

< p > according to the figures of relevant market research institutions, the demand for global carbon fiber market will remain 13% before 2015, and the demand for carbon fiber in China will increase faster than that of the whole world.

It is predicted that by 2015, the total demand of "a href=" http:// www.91se91.com/news/index_c.asp "> carbon fiber < /a" will reach 16 thousand tons.

Driven by the growth of < a href= "http:// www.91se91.com/news/index_c.asp" > demand < /a > P, the development of domestic carbon fiber has accelerated in recent years, and the capacity has been greatly improved.

At present, more than 30 enterprises in China have been engaged in R & D and production of carbon fiber, and their capacity has exceeded 20 thousand tons.

In addition, there are still a large number of carbon fiber production lines under construction and planning in China, but there are still many problems behind the domestic carbon fiber projects.

< /p >

On the one hand, China has to spend a lot of money every year, "a href=" http:// www.91se91.com/news/index_c.asp "," import /a "and more than ten thousand tons of carbon fiber products, so as to meet the needs of national economic development." P "

Data show that in 2013, China imported 12386.2 tons of carbon fiber and its products, an increase of 34.5% over the same period last year, and imports amounted to US $383 million.

On the other hand, China's carbon fiber enterprises are under construction, and the annual production of carbon fiber is less than 3000 tons, which only produces 1/10 of production capacity, and the mass production line is idle.

< /p >

< p > industry insiders say that the low utilization rate of domestic carbon fiber production line is not due to the lack of downstream market demand, but because it is difficult to produce qualified products.

Carbon fiber production process is complex, from polymerization, spinning, oxidation, carbonization, surface treatment, any production link problems, may affect the performance of carbon fiber.

"Most of the raw silk has high impurity content, poor quality stability, large coefficient of variation, no good raw materials, and how to produce good products." although China's carbon fiber production capacity has expanded rapidly in recent years, most of the products are relatively low quality products, and the gap is obvious compared with that of foreign countries. Therefore, the expansion of this capacity also aggravates the structural surplus of carbon fiber to a certain extent.

< /p >

< p > in addition, the current industrial development mode also hinders the application of domestic carbon fiber.

Foreign carbon fiber manufacturers have established extensive cooperative development and stable supply and demand relationship with manufacturers of important applications such as automobile, aerospace and other carbon fibers, and established a complete carbon fiber industry chain.

China's carbon fiber industry is disconnected from scientific research, production and application.

"Often after products are developed, they do not know what they can be applied to, and how they will be used.

< /p >

< p > from the application field, China's carbon fiber also needs to break through in its industrial application.

Taking acrylonitrile based carbon fibers, which account for more than 90% of carbon fiber production, for example, the proportion of industrial applications and sports leisure is 75.7% and 24.3% in the world, while in China, the proportion is 20% and 80% respectively.

In 2013, China imported 5931.6 tons of carbon fiber and its products for sports and leisure, accounting for 47.89%.

< /p >

< p > because of the particularity of the application field of carbon fiber reinforced plastics, the foreign countries have monopolized the blockade of high performance carbon fiber technology and high-end process equipment, dumping low-end carbon fiber products to China, adding to the small and scattered state of China's carbon fiber enterprises, the quality is not stable, and the production cost is higher than that of imported similar products, and the whole industry is in a state of loss.
