The new materials were written into the mid- and long-term planning of the industry at the end of last month. The Ministry of Industry and Information Technology, the National Development and Reform Commission, and the Ministry of Science and Technology were jointly issued (hereinafter referred to as the “Planningâ€). In the “Planningâ€, lightweighting has been recognized as one of the important directions for future automotive development, and advanced automotive materials have become an important part of it.
According to the "Planning", the future will rely on the national science and technology plan to guide the automotive industry to strengthen cooperation with related industries such as raw materials, and jointly carry out industrialization and batch application research of high-strength steel, aluminum alloy high vacuum die-casting, semi-solid and powder metallurgy molding parts, and accelerate Application of magnesium alloy and rare earth magnesium (aluminum) alloy to expand the application range of high performance engineering plastic parts and composite materials. Encourage industry enterprises to strengthen the manufacturing technology of key components such as high-strength lightweight body, key assembly and precision parts, motor and electric drive system, and integrate advanced manufacturing equipment such as automobile complete vehicle technology, key assemblies and parts. Innovation and engineering applications.
According to reports, automotive lightweighting is mainly reflected in the optimization design of automobiles, alloy materials and non-metallic materials applications, which in turn are lightweight weight reduction of automobiles by 10% to 15%, 30% to 40%, and 45% to 55%.
Yu Kai, secretary of the Party Committee of China Automotive Technology and Research Center, said at the "2017 International Forum on Automotive Materials" recently that China's auto industry is entering a period of strategic transformation, upgrading from a big to strong, a new generation of information technology, new energy, new Technology such as materials has accelerated the integration with the automobile industry, the industrial ecology is undergoing profound changes, and the competitive landscape is also fully reshaped. Whether China's auto industry can actively innovate, seize opportunities, and seize opportunities is of great importance. The "Planning" clearly stated that promoting the integration of technology and capital in the relevant industrial enterprises such as vehicle and materials not only pointed out the direction for the development of China's automobile industry, but also put forward requirements for the development of vehicle materials.
Yu Kai introduced that as the basis of the automobile industry, automotive materials are closely related to the safety, environmental protection, energy saving and green performance of automobiles. The advanced automobile industries in Europe, America and Japan have in-depth research and strict requirements on automotive materials. . China's research in the field of automotive materials started late, the foundation is relatively weak, and the industry chain cooperation is not close. Therefore, it is necessary to carry out extensive cross-industry and inter-disciplinary cooperation between automobile manufacturers and materials and parts enterprises and research institutions with advanced technology research and development capabilities, vigorously research and develop new materials and new technologies, and promote material recognition systems for automotive products. Development design and technological innovation provide a constant source of power.
As one of the main ways for energy saving and emission reduction of automobiles, lightweighting has always been the technical direction that the automotive industry is constantly advancing. Ford Motor founder Henry Ford once said that any excess weight is fatal to the car. At present, with the development of new energy vehicles, lightweighting is a top priority.
Zhao Yuzhi, deputy chief engineer of the Chinese Academy of Sciences, said that there are many advantages to lightweighting new energy vehicles. First, they can increase the cruising range and reduce costs. The weight loss of 100 kg can increase the cruising distance by about 10%. At the same time, because the body is light, the weight of the battery can be reduced, thereby reducing costs. In addition, weight reduction can shorten the braking distance and improve safety performance. If the hood is lightened with aluminum alloy, it can also help protect pedestrians.
According to the "Technology Roadmap for Energy Saving and New Energy Vehicles" issued by the China Automotive Engineering Society, the future will be reduced in three stages in the future. The first stage is from 2016 to 2020, achieving a 10% reduction in vehicle weight compared to 2015; focusing on the development of ultra-high-strength steel and advanced high-strength steel technology, achieving a high-strength steel ratio of more than 50% in automotive applications. The second stage is from 2021 to 2025. The vehicle is 20% lighter than 2015. The body uses a variety of mixed materials such as steel and aluminum to increase the proportion of magnesium alloy and carbon fiber parts. The aluminum used in bicycles reaches 350kg. The third phase is from 2026 to 2030, achieving a 35% reduction in vehicle weight compared to 2015. The focus is on the development of magnesium alloy and carbon fiber composite technology to achieve a wide range of applications for carbon fiber composite body and carbon fiber components. Up to 45kg, carbon fiber usage accounts for 5% of the weight of the car.
At the same time, car lightweighting is also directly related to energy saving and emission reduction. According to the "Plan", by 2020, the average fuel consumption of car companies must be reduced to 5 liters per 100 kilometers. According to statistical estimates, if the vehicle's overall weight is reduced by 10%, fuel efficiency can be increased by 6% to 8%, and if fuel consumption can drop to 0.3 to 0.6 liters per 100 kilometers, carbon oxide emissions will be reduced by 5 to 8 grams.
In this regard, Yu Kai said that the lightweight of automobiles has risen to the national strategic level. Not only does China Manufacturing 2025 be listed as the core technology for the development of energy-saving and new-energy vehicles, but also successively in the Ministry of Industry and Information Technology, the National Development and Reform Commission, the Ministry of Science and Technology and other national ministries. In the special program released, the specific requirements for the development of lightweight technology have also been put forward many times. The achievement of automotive lightweight targets is inseparable from the application of lightweight materials such as high-strength steel, magnesium alloys, high-performance plastics and carbon fiber composite materials. The innovation and development of material technology has become an important way to promote the revolution of vehicle lightweight technology. .
Accelerating the promotion of green manufacturing has institutional forecasts. With the help of the transformation and upgrading of the automobile industry, the market size of the automotive new materials industry is expected to reach several trillion yuan. However, industry insiders believe that there is still a gap between China and developed countries in terms of lightweighting and new automotive materials. This is mainly manifested in: the variety, quantity and performance of China's materials are very different from those of foreign countries; the domestic automobile industry, especially the joint venture brand has a self-contained supplier system, and the domestic material enterprises have entered very difficult, resulting in the development of domestic material enterprises. Lagging behind the automotive industry; material and processing cost control is difficult, carbon fiber and other composite materials due to low processing efficiency, resulting in increased cost of auto parts and OEMs; China has no complete new material technology and product standards, automotive companies and materials companies The integration is not enough.
In this regard, Gao Yunhu, Director of the Energy Conservation Department of the Ministry of Industry and Information Technology, said that it will accelerate the construction of a green manufacturing system for the automobile industry. It is necessary to do a good job of energy conservation and emission reduction, reduce the cost of reducing costs, and improve the quality and efficiency. Under the general environment of China's economy entering a new normal, we must actively cultivate new kinetic energy for green development. As the pillar industry of China's national economy, the automobile industry has a long industrial chain, a large degree of correlation, and a wide range of radiation. Accelerating the green manufacturing of the automobile industry and realizing green growth have important practical significance and far-reaching historical significance.
It is understood that the "Planning" clearly puts forward the goals and main tasks of promoting the green development of the automobile industry, and also puts forward clear requirements on the fuel consumption of vehicles, vehicle recycling rate, and green management of the whole life cycle. Industry analysis, strengthening the green life management of the automotive industry, is to vigorously improve vehicle fuel efficiency, significantly reduce emissions and energy consumption, while promoting the green design and green supply chain of automobiles, and then build a green manufacturing system for the automotive industry. .
Gao Yunhu said that in the next step, the Ministry of Industry and Information Technology will further promote green design demonstration and green design product evaluation pilot. In the automobile, electronic appliances, machinery, large-scale complete sets of equipment and other industries, select a group of leading enterprises with strong representativeness, large industry influence, strong production and management strength and high management level, supported by green supply chain standards and production responsibility system extension system. , carry out pilot demonstration of green supply chain. At the same time, strengthen supervision and management, strengthen coordination and cooperation with relevant departments, strengthen post-event supervision, and gradually establish a market supervision mechanism for green design products.
