Among the world's carbon fiber technology research and development power in China, what we lack in this competition?

2016-09-28

Carbon fiber is high-performance fiber such as aviation, spaceflight, national defense construction, economic construction and scientific and technological progress in areas such as the indispensable main strategic materials, is also one of the core of lightweight technologies in low carbon economy. Under the impetus of the relevant national policy in recent years, rapid development of carbon fiber industry in China,

technology optimization, constantly improve production equipment, applications continue to expand, successfully solved the problem of "from scratch". Recently, the carbon fiber industry conference of a high end - "carbon fiber industry technology development seminar and 2016 Chinese chemical fiber industry association carbon fiber branch conference" in shandong weihai, delegates to focus on the future development direction and emphasis of carbon fiber in our country to do strongly does.

Effective capacity is about 15000 tons of carbon fiber in China in 2015, the annual production of around 3500 tons, slightly down from the previous year, the weihai expand, double seals, jiangsu heng god, jilin carbon valley, the big river, Shanghai petrochemical, seven companies such as zhejiang fine work basically maintain the stability of the hundred - ton above production.

Look at the international, 2015, the global production capacity of 142000 tons of PAN based carbon fiber (small tow (70%), the top five companies for toray, teijin, Germany SGL, mitsubishi and Zoltek companies in the United States, accounting for 60% of global capacity, including toray accounted for about 18% of production capacity.

"Toray also announced plans to invest 100 billion yen, 2020 in the United States to build a new high performance carbon fiber production line,

annual output of 2000 tons. The early mitsubishi recent statement, also be supplemented to its greater business investment in equipment, the large tow carbon fiber capacity can be increased from the current 2700 tons to 2700 tons. New equipment is expected in the third quarter of 2017 and put into production. By 2017, will the output of mitsubishi from the current 10100 tons to 13300 tons, increases by about thirty percent." Zhang Dingjin is introduced.

Relevant data show that 2015 PAN based carbon fiber in the world of the total consumption of about 60000 tons, aviation, industrial and sports/leisure industry occupies 22%, 62% and 16%, respectively. "Demand for carbon fiber was bigger industry have wind, mold plastic, pressure vessels, and car." Zhang Dingjin predicts that by 2020, demand of carbon fiber will reach 100000 tons, 72% of which will be used in the industries of auto industry and wind power.

Currently, car ownership in China is about 150 million, 70% of the oil used for motor vehicle fuel, is expected to car ownership for 300 million to 2025, the national energy development strategy is difficult to meet the growing demand, vehicle emission haze caused by environmental degradation to be solved. Lightweight technology is to reduce automobile fuel consumption, reduce emissions, improve the electric range, one of the most effective method to engineering is put forward by the "made in China 2025" one of the core technology and core competitiveness, and the high performance fiber composite materials is the most effective engineering material lightweight technology. Donghua university professor yu wood fire, almost all the global auto companies are to develop carbon fiber car research and development, at the same time, carbon fiber parts enterprise, resin matrix, composite materials, and other enterprises are also in research and development of carbon fiber car parts.

"BMW i3 & i8 is using carbon fiber composite material used in automobile lightweight design model of BMW's current production of about 100 vehicles per day i3 and 10 ~ 20 i8, manufacturing process than traditional automotive power saving, water saving 70% 50%. The BMW i3 has on the market in Germany in 2013, the current order far beyond scheduled production capacity, the i3 is rapidly increasing production capacity." Zhang Dingjin is introduced, the future automobile industry on the demand of carbon fiber will continue to maintain growth, by 2018 global demand of carbon fiber in the automotive field will be around 8600 tons, 2024 tons by 2024.

Weihai gloway composite material co., LTD., the board secretary, deputy general manager ying-chao wang said that although domestic carbon fiber can solve the problem of "from scratch", but it is still low, compared with the United States, Japan and so on carbon fiber power, domestic carbon fiber one's current level of technology, manufacturing and quality stability and a larger gap.

Doing "terminal manufacturing cost accounting, according to the existing intermediate market price calculation concluded that cost is too high, plan directly deny the use of carbon fiber parts. Is the most important thing at this stage, the carbon fiber industry should clearly tell the true costs of manufacturing scale application, do not use the unreasonable price, scare a lot of want to use carbon fiber manufacturing." Yu wood fire.

At present, the international carbon fiber production enterprises constantly committed to developing low-cost production technology. Yu wood fire, American oaks national laboratory in 2001 began to study the preparation of carbon fiber, low cost 2016 technology licensing, the big tow acrylic + microwave plasma carbonizing technique can cut costs by 50%; Japan's "PAN aromatic ring + microwave plasma carbonizing" technology, 10 times to raise the production efficiency.

Happily, donghua university is also developing carbon fiber low cost production of new technology, the research of "PAN aromatic ring + melt or dry jet wet spinning + fast oxidation technology, an authorised person of the 2 invention patents, Japan authorized invention patent 5 pieces, three pieces of Chinese patent application for invention. At present, the technology is in the pilot phase.

"Japan represents the future innovation direction of carbon fiber, carbon fiber and its composite materials research and development goals, in addition to adapt to specific purposes, especially in the field of aerospace and defense special demand, the domestic carbon fiber industry is continuously developing new resin system, and the CFRP embedded fiber Bragg grating sensor parts." Yi-feng luo is put forward.

Currently, about more than 30 carbon fiber enterprises in our country, overall scale small, with annual output of 30000 tons of international leading enterprises can't compete. Yu wood fire thinks, our country urgently need to establish large tow carbon fiber technology used in industry and its industrial chain, at the same time support small tow carbon fiber, large tow carbon fiber manufacturing technology research and development, the overall level of industrial technology in industrial applications in promoting carbon fiber.

Yu wood fire also suggested that the future shall establish a number of "high performance fiber and light industrial demonstration project", formed the industrial chain has the reasonable utilization of each link, the continuous and stable operation, reasonable profit full demonstration project; Breeding industry leading enterprises, improve the economies of scale, participate in international competition; Set up a "high performance fiber and lightweight" key science and technology projects, strengthen scientific research; Build high performance fiber and lightweight technology in China science and technology and talent training system; Develop high performance fibers in our country and lightweight composite material industry development policy, optimize the development environment.

Star effect of carbon fiber, and huge development potential for the industry itself, was in the capital market, capital market has a "carbon stocks".

At present, some of the concept of carbon fiber a-share companies, such as and help biological, shenda shares in the capital markets platform, aims to non-public shares to raise funds investment carbon fiber; Constant god shares have done twice through the new three board market financing; Jilin carbon valley also listed in February. At present, the a-share listed companies involved in carbon fiber business have nine, including catic high-tech, square big carbon, calling from huaxun ark, Shanghai petrochemical, etc. At the same time, the new three board listed companies have three, including constant god shares, jilin carbon valley, grandsoo new material.

"Geared to the needs of domestic carbon fiber industry has walked out of the capital market as A first step, although not carbon fiber as the main business of a-share listed companies, but with carbon fiber as the extension of the business of the listed company has several, initially formed carbon fiber stocks." Ying-chao wang is introduced.
