New materials experts call on China's R & D capability

Core hints: carbon fiber is known as the "king of new materials", which plays an important role in supporting the transformation and upgrading of China's manufacturing industry and the security of national defense. However, the reporter recently learned from the carbon fiber industry development forum, China's carbon fiber industry in recent years has made considerable progress, but subject to the development ability is low, uneven quality problems such as discourse in the international carbon fiber market right of Chinese enterprises is weak, market dominance in the United States, Japan and other developed countries within the enterprise advantage. The participants and experts and scholars in the conference urgently appealed that it is urgent to strengthen the guidance and support of the carbon fiber industry.

Carbon fiber, known as the "king of new materials", plays an important role in supporting the transformation and upgrading of China's manufacturing industry and the security of national defense. However, the reporter recently learned from the carbon fiber industry development forum, China's carbon fiber industry in recent years has made considerable progress, but subject to the development ability is low, uneven quality problems such as discourse in the international carbon fiber market right of Chinese enterprises is weak, market dominance in the United States, Japan and other developed countries within the enterprise advantage. The participants and experts and scholars in the conference urgently appealed that it is urgent to strengthen the guidance and support of the carbon fiber industry.

China's carbon fiber production is only 3.2% of the world.

"With the use of carbon fiber components, the weight of BMW I3 is 20% lighter than the world's best - selling electric car." "Not just the automotive industry, at present, the application of carbon fiber in various fields has begun to blowout. The technological progress and cost reduction of the whole industry chain is the key to China's success and failure."

In late January, Jilin chemical fiber group hosted the Jilin Province carbon fiber industry technology innovation strategic alliance members of Congress and the carbon fiber industry development forum "held in Jilin City, more than 200 business people attended by experts and scholars, accounted for almost half of the country China field of application and development of carbon fiber. It can be seen that each face has an urgent expression on each face.

It is understood that the density of carbon fiber, low strength, quality is lighter than aluminum, the strength is higher than that of steel, but with soft textile fiber processing, can be described as "an hand in a velvet glove", and corrosion resistance, high temperature resistance, fatigue resistance, impact resistance, and low thermal expansion coefficient, good thermal conductivity properties and the electromagnetic shielding, so it is called "the king of new materials".

"The total output of global carbon fiber in 2014 is about 100 thousand tons, which is mainly monopolized by Japanese and American enterprises, and the actual output of China is only about 3200 tons." Zhao Xiangdong, vice president of the China Chemical Fiber Industry Association, predicts that domestic carbon fiber demand will reach 15 thousand tons in 2015.

In the first half of last year, the import of carbon fiber and products in China reached 5513.2 tons, because the current production could not meet the demand. In the future, the four major industries of China, large aircraft projects, offshore wind power generation, light weight development and high-speed railway, will undoubtedly drive the strong growth of carbon fiber demand.

"If the domestic carbon fiber industry to seize the time to catch up, the future Chinese several industry fear is difficult to not heteronomy." The participants said anxiously.

Weak technology and high production cost

"The weakness of equipment technology, the stability of product quality and the backward development of applied technology are all the bottlenecks restricting the development of China's carbon fiber industry". Zhao Xiangdong outspoken.

With regard to carbon fiber technology, foreign countries have been strictly blocking our country. In 1960s, China began to study itself, but there is still a gap between the performance of our main products and the international advanced level.

In order to achieve the development of "Baotuan", in June 2014, Jilin chemical fiber group launched the strategic alliance of Jilin carbon fiber industry technology innovation. 23 of the more than 30 carbon fiber enterprises in China are members of the alliance, and there are 10 universities and research institutes.

It is reported that relying on the alliance to provide a platform of carbon fiber electric heating in Jilin Province Dongfeng Chemical limited liability company production cold vest, have been allotted sanitation workers try, floor heating products of carbon fiber also has completed trial; Jilin Seekon carbon fiber Technology Development Company to undertake a carbon fiber composite material technology development North car group required high iron......

Song Dewu, chairman of Jilin chemical fiber group, pointed out that although the work of the alliance has made some achievements, the technology closure among member units needs to be further opened, and the pace of original innovation and technological achievement transformation needs to be speeded up.

It is reported that the high cost of production is a common problem for many enterprises in China. This also leads to the increasing demand for the market, but at present, the enterprises in the carbon fiber industry union of Jilin have not yet realized full full load production.

"At the moment, the scale of China's carbon fiber enterprises is too small, and the total capacity of the more than 30 enterprises in the country is not as good as that in Japan and Dongli, so it is difficult to compete with the international giants in the industry." Yu Muhuo, a professor at the Donghua University, said.

The future focus is on the scale of industry and the problem of industrial chain

At present, many countries are actively planning to develop carbon fiber industry as an important support to seize the next round of industrial and national defense competition. Take the automobile industry as an example, according to Cao Du, President of Changan Automotive Design Institute introduced the application of carbon fiber material on the body, can greatly reduce the weight and the weight of each minus 10%, can be reduced by 6% ~ 8% of the fuel consumption, reduce emissions from 5 to 6%, and help to improve the vehicle's acceleration and braking performance. To this end, Japan plans to invest 2 billion yen in the next 5 years, supporting the cooperation between carbon fiber raw material enterprises and automobile main engine plants, while the US Department of energy will provide 21 million 750 thousand yuan of financial support for similar projects in the next two years.

"If Ford creates assembly line production is the first revolution in the car industry, carbon fiber + new energy may be the second car revolution. As the world's largest automotive production and marketing country, China must grasp the future trend of automobile development. If China's brand cars are not ready for early layout, they may be thrown away again. Cao Du is in a hurry.

It is understood that in order to develop carbon fiber industry and support the transformation and upgrading of manufacturing industry in China, in 2013, the Ministry of industry and Commerce formulated the action plan for accelerating the development of carbon fiber industry. In August 2014, China's carbon fiber and composites industry development alliance was also established in Beijing.

"Subject to the development ability is low, uneven quality problems such as discourse in the international carbon fiber market power enterprises in our country is weak, let some of the international carbon fiber industry giant advantage." In the day of the forum, many people in the industry believe that China still needs to continue to increase the guidance and support of the carbon fiber industry.

"No scale does not become an industry, and the focus of the future is the scale of industry and the problem of industrial chain." Professor Yu Muhuo pointed out that in the face of the broad application prospects of carbon fiber, we should play the national will, train a batch of industrial chain enterprises, cultivate 1~2 leading enterprises in every link, and establish R & D capabilities together with research institutes to support the leaping development of the industry.
