At the beginning of 2013, China's first dump truck equipped with a carbon fiber composite car was off the assembly line. The car had a length of 8.6 meters, a load of 50 tons, a weight of 4.8 tons, and a weight reduction of 29% compared with the metal body. This is a composite material in domestic heavy trucks. The successful application for the first time marks a new breakthrough in the application technology of composite materials in the automotive lightweight field and opens the “blue ocean†of carbon fiber applications.
Lightweight car becomes a trend
Lightweight vehicles means that, under the premise of ensuring the strength and safety performance of automobiles, the quality of automobile trims should be reduced as much as possible, thereby improving vehicle dynamics, reducing fuel consumption, and reducing exhaust pollution. Research shows that if the vehicle's vehicle weight is reduced by 10%, the fuel efficiency can be increased by 6% to 8%; for every 100 kg of vehicle curb weight, the fuel consumption per 100 kilometers can be reduced by 0.3 to 0.6 liters, the weight of the vehicle can be reduced by 1%, and the fuel consumption can be reduced. 0.7%. In addition, for every 100 kilograms of vehicle weight reduction, CO2 emissions per kilometre can be reduced by about 5 grams. Experts said that the current automotive industry is facing serious challenges of resources and the environment, and advancing the weight of automobiles has become the trend of the world's automotive development.
Car lightweight, carbon fiber is placed high hopes. Carbon fiber has the advantages of low processing energy consumption, light weight, high strength, strong designability, corrosion resistance, and good molding process. It has become an ideal material for lightweight vehicles, especially for carbon fiber applications in electric vehicles.
“The reduction of weight, fuel economy, and environmental protection are important performance indicators for the automotive industry. Therefore, the application of carbon fiber in this field has attracted the attention of governments and related companies in the world. For example, the United States invests about 200 million U.S. dollars every year to implement a lightweight car body. The five-year development plan; Japan's Nissan Motors and Honda Motors will also jointly develop new carbon fiber materials for the automotive body with Toray. It is estimated that by 2019, the demand for carbon fiber in the automotive industry is expected to increase to 9300 tons." (Beijing) Institute of Information Technology Institute Industrial Planning Research Institute, said Jian-Bo.
For our country, the significance of vehicle lightweighting is even more significant. On the one hand, China is a large consumer of automobiles. By the end of 2012, the country’s vehicle ownership has exceeded 120 million vehicles, an annual increase of 15.1 million, and this trend will continue to be maintained. Such a huge amount of car ownership has exerted tremendous pressure on energy and the environment. The "China Low-carbon Economic Development Report" released this year shows that among the major sources of PM2.5 emission in the Beijing-Tianjin-Hebei region, motor vehicle emissions and road dust account for 50%; the relevant report released by the Ministry of Environmental Protection also shows that motor vehicle emissions have become a part of Major sources of atmospheric pollution in large and medium cities. On the other hand, the Chinese government has explicitly promised that by 2020, CO2 emissions per unit of GDP will be 40% to 45% lower than in 2005. This is undoubtedly a very arduous task. "This gives a huge market for the development of carbon fiber composite automotive parts and components." said Duan Xiaoping, president of the China Chemical Fiber Industry Association.
Domestic enterprises should seize opportunities
Experts said that China’s auto lightweight has ushered in a rare opportunity for historical development. First, after many years of research and accumulation, at present, China has basically broken through the body of lightweight design techniques and evaluation methods, fiber-reinforced plastic modular design and application technology, and a variety of lightweight technology integration applications such as the goal of vehicle weight reduction, etc. Quantify key technologies. Second, policy support has increased. China has successively promulgated the “Energy Conservation and New Energy Vehicle Industry Development Plan (2012-2020)†and the “New Materials Industry Twelfth Five-Year Development Plan†to explicitly encourage the development and application of lightweight automotive technologies. The "Industrial Transformation and Upgrading Investment Guide" issued by the Ministry of Industry and Information Technology also places the weight of automobiles on the prominent position of the automotive industry.
Some companies have already carried out their work in light weight. Changzhou Shenying Carbon Plastic Composites Co., Ltd. invested 330 million yuan to build 200,000 carbon fiber roof panels, hoods, and bumper production lines in Wujin Economic and Technological Development Zone in Changzhou; Great Wall Motor and Chery Automobile also cooperated with foreign companies. To promote the application of lightweight materials.
Experts believe that with the continuous development of China's carbon fiber industry, energy-saving emission reduction and the general direction of automotive lightweighting guidelines, carbon fiber materials or will become the auto industry "slimming revolution" leader.
