Teijin and General Motors jointly develop advanced carbon fiber composites

Tokyo Teijin Co., Ltd. and General Motors recently signed an agreement on the joint development of advanced carbon fiber composites technology. If the project is successful, carbon fiber will take a new step in the mass production and application of automotive products

carbon fiber is a member of the family of high-performance fibers. High performance fiber has the characteristics of light weight and high strength, which is of great significance to realize low-carbon economy, stimulate consumer demand, and drive the upgrading of traditional industries

the international carbon fiber market was originally monopolized by Japanese and American enterprises. Japanese enterprises promoted the establishment of regional emission reduction cooperation mechanisms and trading systems for energy conservation, carbon emission rights, emission rights, water rights, etc., accounting for 50.5% of global production capacity, while American enterprises accounted for 27.5%. The sales volume of carbon fiber in Japan has increased significantly in the three major markets of aviation, sports and leisure, and industry. The export volume also increased from 57.2% in 1991 to 78.6% in 2010. According to the statistics of Japan carbon fiber manufacturers association, in 2010, Japanese carbon fiber manufacturers, including Toray, Toho rayon, Mitsubishi Rayon and other enterprises, sold 16000 tons of carbon fiber annually, an increase of 66.2% year-on-year

for the carbon fiber industry, Japan's technology strategic plan is also in full bloom, adding high-tech fibers to 25 fields, such as the development of large-scale and low-cost carbon fiber efficient manufacturing technology. The innovation plan in the fiber field covering carbon fiber in the United States is to selectively focus on the high-tech fiber field, which may take several hours to develop several high-performance fibers and functional fibers

the agreement between the two companies requires the use of carbon fiber thermoplastic reinforced plastic (CFRTP) technology independently developed by teiren. In the automobile manufacturing industry, this technology has not been used on a large scale. Compared with the traditional method of using thermosetting resin to produce carbon fiber composites, this method is faster and more effective, and the molding time is shorter. In addition, the thermoforming cycle of CFRTP is short, less than 1min, so it is easy to mass produce

the head of Diren said, "our cooperation with GM is of great significance. The use of carbon fiber materials in GM parts can greatly reduce the weight of the body, which is conducive to GM's taking the initiative in the market; secondly, it is conducive to promoting the use of green composite materials in the automotive industry and reducing pollution."

for Teijin, the agreement can increase their market share of advanced carbon fiber applications and correctly adjust their investment portfolio. According to the agreement, Teijin will establish a composite material application center in the north of the United States in early 2012. Diren and Ge have an obvious intention to seize the world's advanced composite carbon fiber market through cooperation

the development direction of China's carbon fiber and other high-tech fiber industries is: high performance, high stability, high efficiency and low cost, gradually establish a public platform for PAN carbon fiber key technologies, form carbon fiber technical standards and specifications, build a domestic carbon fiber patent system, and form the core competitiveness of China's carbon fiber industry. For example, expand the application fields of civil and offshore oil development, intelligent electricity construction and other high-end markets such as medical equipment, and develop carbon fibers with low cost and stable performance that can meet the strength and modulus requirements of different application fields; Develop low-cost manufacturing technology. In the total cost of composite products, the manufacturing cost accounts for 70% - 80%, and the material cost only accounts for about 20%; Industrial policy guidance and support, cultivate carbon fiber core enterprises, and coordinate the development of the industrial chain; Strengthen international exchanges, increase investment in product research and development and market development, and promote talent introduction and joint venture cooperation

the national "Twelve modernizations" is by no means the so-called "Westernization" five plan. The output of building steel structures is 36million tons, 41million tons and 46million tons respectively. The plan also clearly points out that we should take technology as the core and application as the traction to vigorously promote the development of carbon fiber and advanced composite industry. This has created a good environment and conditions for the take-off of China's carbon fiber industry
