The market size or trillions of new automotive materials
New energy, intelligence and light weight have been recognized as the direction of development of automobile industry in the future. With the acceleration of industrial transformation and upgrading, new automotive materials have also become the focus of attention.
New materials are written into the medium and long term planning
At the end of the month, Ministry of national development and Reform Commission, the Ministry of science and technology, three ministries jointly issued the "automobile industry long-term development plan" (hereinafter referred to as the "plan"). In the "planning", lightweight is one of the important directions of future automobile development, and the material of advanced vehicle is one of the important contents.
According to the "planning", the future will rely on national science and technology plan, guide the automotive industry and raw materials and other related industries to strengthen cooperation, industrial research and application of mass collaboration to carry out high-strength steel and Aluminum Alloy high vacuum die casting, semi-solid forming and powder metallurgy parts, accelerating magnesium alloy, rare earth magnesium (aluminum) alloy application, high expansion the performance of engineering plastic parts, the scope of application of composite materials. Manufacturing technology industry encouraged enterprises to strengthen high-strength lightweight body, the key assembly and precision parts, motor and electric drive systems and other key parts, key technology, development of automobile vehicle assembly and parts of advanced manufacturing equipment integrated innovation and engineering application.
According to introduction, vehicle lightweight is mainly reflected in the optimization design of automobile, the application of alloy materials and non-metallic materials, and the lightening weight of vehicles is 10% to 15%, 30% to 40%, 45% to 55%, respectively.
Said Chinese Automotive Technology Research Center Party Secretary Yu Kai in the recently held "2017 Vehicle Materials International Forum", China's automobile industry is entering the transformation and upgrading, from large to strong strategic opportunities, new generation of information technology, new energy, new materials and technology to accelerate the integration of the automobile industry, industrial ecology are profound changes in the pattern of competition is comprehensive remodeling. Whether China's auto industry can actively innovate, seize the opportunity and seize the opportunity, it has a great relationship. The plan clearly puts forward that promoting the integration of technology and capital by vehicle and material related industry enterprises not only points out the direction for the development of China's automobile industry, but also puts forward requirements for the development of vehicle materials.
Yu Kai introduced that, as the basis of the automotive industry, vehicle materials are closely related to the safety, environmental protection, energy saving and green performance of automobiles. Advanced automotive industries in Europe, America and Japan have in-depth research and strict requirements for automotive materials. In China, the research on the field of vehicle materials is late, the foundation is weak, and the cooperation of industrial chain is not yet close. Therefore, to automobile production enterprises and has the ability of advanced technology research and development of materials parts enterprises and research institutions, extensive cross industry, cross major depth cooperation, vigorously develop new materials and new technology, the implementation of material approval system, Everfount provide power for the car design and product development technology innovation.
Light weight of automobiles is of great significance
As one of the main ways of automobile energy saving and emission reduction, lightweight has always been the technical direction of the automobile industry. Henry Ford, the founder of Ford, once said that any extra weight is a fatal injury to a car. At present, with the development of new energy vehicles, the weight of light weight is the most important.
Zhao Pizhi, deputy chief engineer of the Chinese Academy of Sciences, said that the new energy vehicle lightweight has many advantages, first of all, it can increase the distance of life and also reduce the cost. The weight loss of 100 kg can increase the distance of about 10%. At the same time, because the body is light, the weight of the battery can be reduced, thus reducing the cost. In addition, weight reduction can shorten the braking distance and improve safety performance. If the hood is lightweight with aluminum alloy, it can also help to protect pedestrians.
According to the "energy saving and new energy vehicle technology roadmap" issued by the China Automotive Engineering Society, the car will lose weight in three stages in the future. The first stage is from 2016 to 2020, and the vehicle weight loss is 10% than that in 2015. The development of ultra high strength steel and advanced high strength steel technology is focused on, so that the proportion of high-strength steel in automotive applications reaches over 50%. The second stage is from 2021 to 2025, to achieve vehicle weight loss of 20% over 2015. The body uses steel and aluminum and other mixed materials to increase the application ratio of magnesium alloy and carbon fiber components, and the amount of aluminum for single vehicle reaches 350kg. The third stage is from 2026 to 2030, the vehicle lost 35% than in 2015, focusing on the development of technology of magnesium alloy and carbon fiber composite materials, a wide range of application of carbon fiber composites and carbon fiber hybrid body parts, bicycle with magnesium alloy reaches 45kg, the use of carbon fiber weight accounted for 5%.
At the same time, the light weight of automobile is also directly related to energy saving and emission reduction. According to the plan, by 2020, the average fuel consumption of car enterprises must be reduced to 5 liters per hundred kilometers. After statistical estimation, if the vehicle weight is reduced by 10%, the fuel efficiency can be increased by 6% to 8%, and if the fuel consumption can be reduced to 0.3 to 0.6 liters per 100 km, the emission of carbon dioxide will be reduced to 5 to 8 grams.
In this regard, in Kay said, automobile lightweight has risen to the national strategic level, "2025" will not only Chinese manufacturing lightweight as the core technology development of energy-saving and new energy vehicles, special programs in the Ministry of national development and Reform Commission and the Ministry of science and technology and other ministries have issued, also put forward specific requirements for many times the development of lightweight technology. The achievement of lightweight vehicle target is inseparable from the application of lightweight materials such as high-strength steel, magnesium alloy, high-performance plastics and carbon fiber composite materials, and the innovation and development of material technology has become the goal.
