Significant progress has been made in China's high-performance fiber and vehicle lightweight technologies

A few days ago, "High-performance fiber and automotive lightweight technology innovation development strategy research" project conference was held in Beijing. The project proposed China's high-performance fiber and light vehicle development strategy and technical approach, high performance fiber and light industry, key engineering and special projects, and high performance fiber and light industry development proposals, the research results for the government decision-making management, Enterprise innovation and development provide a strong scientific and technological support.
Chinese Academy of Engineering Department of Environmental and Light Textile Engineering Jiang Shicheng, Yu Mingfang, Yao Mu, Yu Jianyong academician, Chinese Academy of Engineering Bureau of Secondary School Qi Qi, deputy director of NDRC Industrial Coordination Department Lu Wei, deputy director of the Ministry of Industry and Consumer Goods Cao Xuejun, Cao Guoying, deputy director, as well as from China Chemical Fiber Industry Association, China Society of Automotive Engineers, China Association of Automobile Manufacturers, China Automobile Lightweight Alliance, China Association of Composites, China Textile Industry Federation, China Textile Academy, China Textile Academy, International Relevant leaders of automobile light weight green technology alliance, automobile enterprises, carbon fiber enterprises, composite materials enterprises and relevant university institutes and experts and scholars totaled more than 80 participants.
Academician Jiang Shicheng briefly introduced the project background and related work. In 2015, the Chinese Academy of Engineering set up a consulting project on the strategic research on the innovative development of high-performance fiber and light-weight automotive technology. Led by academicians in the field of textile industry, the Academy of Engineering invited inviting academicians in the fields of textile, automobile, composite materials and light industry machinery to participate in the project. Donghua University, the State Key Laboratory of Modification of Fiber Materials, Civil Aviation Composites Collaborative Innovation Center and the Shanghai Lightweight Structural Composites Key Laboratory specifically organized and implemented. The project focused on domestic and international high-performance fiber and its light-weight technology-related industries, science and technology development environment and the status quo and development trends; China's high-performance fiber and light-weight technology-related industries in the field of cutting-edge technology conducted an in-depth systematic analysis and research, Understanding and important research results. The project proposed China's high-performance fiber and light vehicle development strategy and technical approach, high performance fiber and light industry, key engineering projects, and high performance fiber and light industry development proposals, and formed a project research report, research 15 copies of the report, submitted a suggestion 1 academician.
Project Secretary-General Professor Yu Wood fire done a project research results report. The research results of the project show that automobile is one of the pillar industries in China. New energy vehicles are a national strategic emerging industry. It is planned that the number of new energy vehicles will reach 5 million by 2020. Lightweight technology is the only way to save energy and reduce emissions and improve the mileage of electric vehicles. Almost all automobile manufacturers at home and abroad have carried out R & D of carbon fiber composite materials vehicles or parts, but encountered a series of bottlenecks in development. The main aspects involved are: Design Guidelines, Databases and Evaluation Criteria for Composite Vehicles and Components; Composites Components Automated production technology and equipment; from carbon fiber to composite materials throughout the automotive industry chain cooperation mechanism; carbon fiber vehicle maintenance, recycling and recycling technology system; automotive low-cost carbon fiber and its intermediate material industry chain; lightweight technology innovation system, Lack of investment in science and technology; has the basis of automotive disciplines and materials disciplines cross-disciplinary talent pool. High-performance fiber is a national strategic material, but also an important part of the new material industry. However, due to the lag of carbon fiber technology used by the terminal enterprises, the enterprises are small in scale and weak in resistance to risks. They are suppressed by the price cuts of foreign-scale enterprises and the operating rates are low. Most enterprises suffer losses, affecting the quality stability and operating costs. In response to the bottleneck encountered in the development of China's automotive lightweight composite materials industry, the project team made the following suggestions on the development of high-performance fiber and light-weight automotive industry: Establishing a number of "demonstration projects of high-performance fiber and lightweight industrial chain" to form the industrial chain Each link has a reasonable rate of operation, continuous and stable operation of a reasonable demonstration of the integrity of the project; fostering leading enterprises in the industry to improve the economies of scale, participation in international competitions; the establishment of "high performance fiber and light" key science and technology, increase scientific and technological efforts ; The establishment of China's high-performance fiber and light technology technology and personnel training system and high-performance fiber and light of the national laboratory or national key laboratory, national engineering laboratory, national knowledge service platform; development of China's high-performance fiber and its lightweight Composite materials industry development policy, optimize the industrial development environment.
Jiangsu Aoxin new energy vehicles, Beijing Automobile Co., Ltd., China Compass Eagle Carbon Fiber Co., Ltd. and Jilin Chemical Fiber Co., Ltd. and other four representatives of enterprises for carbon fiber in the new energy vehicles, carbon fiber production technology in the application of technology, carbon fiber Efficient production technology, carbon fiber precursor production technology to make a keynote speech. Relevant leaders and industry experts attended the meeting on automotive lightweight carbon fiber composite materials industry development and other issues for extensive exchange and discussion.
