Du Shanyi, an academician of the Chinese Academy of Engineering: Carbon fiber materials for military and civilian integration, and there is much to be done in the field of automotive lightweighting
Carbon fiber is a new form of technology that emerged in the 1960s and 1970s. This technique appeared to be subversive at the time. It can transform plastic into structural materials, which can transform the properties of plastics into aluminum alloys. But the weight is lighter. Therefore, the emergence of carbon fiber first received the favor of defense aerospace.
Since 1975, China's carbon fiber has been developed for more than 40 years. Now China's carbon fiber has the capacity to produce high-performance carbon fiber products. From the current situation, it can basically meet the needs of aerospace and defense. It is also expanding to other areas such as automobiles.
The integration of military and civilian is a national strategy. Carbon fiber as a new strategic material is first and foremost with private enterprises to take the lead in research and development, and the urgency of military work, and gradually extend to the civilian sector, such as the automotive industry. Now we can see carbon fiber in, for example, marine engineering, Automotive engineering, orbital engineering, including civil engineering construction, has applications. The development of carbon fiber is the result of military-civilian integration.
The carbon fiber structure is strong, the weight is light, and the weight reduction is not only a problem of reducing costs, but also saves energy and protects the environment. There are three aspects to consider in terms of weight reduction: the first is to use and use high-performance materials; the second is to manufacture, Only manufacturing can guarantee lightweight; the third is design, lightweight, the whole concept design is very important. Lightweight applications in the automotive field are promising, especially new energy vehicles. New energy vehicles will reach more than 6 million vehicles in 2025. Energy car battery itself is very heavy, so weight reduction for the body structure is the key. Unlike aerospace, car production is very large, if the car can make good use of lightweight materials, this is environmental protection, energy conservation and the car itself. The performance is good.
Hou Fushen, Deputy Secretary General of China Automotive Engineering Society, Secretary General of Automotive Lightweight Alliance: Energy-saving new energy vehicles are users with huge potential applications for carbon fiber materials
According to the energy-saving and new-energy vehicle technology roadmap released by the Society in the previous year, by 2030, China's automobile production and sales will reach 38 million, and the market share of new energy vehicles will exceed 40%. The automobile industry will basically realize the electrification transformation.
Under the background of the new round of automobile industry reform, the automobile industry is accelerating in the direction of low carbonization, informationization and intelligence. Among them, low carbonization is the most urgent task we are currently facing, and it is also the realization of the automotive industry. The basic premise of sustainable development. Among them, lightweight technology has become an important technology to support the development of energy-saving and new energy vehicles.
Recently, the National Development and Reform Commission has publicly solicited opinions on the investment regulations for the automobile industry. Among them, new energy vehicles are the first of the four key development areas, and lightweight is listed as the first of the key technologies for new energy vehicles. It can be seen that lightweight technology The future development of new energy vehicles has a huge impact. The Society attaches great importance to the work of lightweight vehicles. From 2007, it established the Automotive Lightweight Technology Innovation Alliance, in the common technology research, technical standards development, industry technology exchange, results transformation and promotion and talents. Training and other aspects have done a lot of work, representing the power of China's automotive lightweight technology innovation.
From the perspective of the alliance, carbon fiber composite materials can greatly reduce the weight of automotive products, and are the best lightweight materials in the field of energy saving and new energy vehicles. In the energy saving and new energy vehicle technology roadmap released by the society, the carbon fiber composite materials are proposed. In the future development goal, by 2020, the cost of using carbon fiber materials in automobiles will be 52% lower than that in 2015. In 2025, carbon fiber usage will account for 2% of the weight of vehicles, and the cost will be 50% lower than the end of 2020. Carbon fiber in 2030 The usage accounts for 5% of the total weight of the vehicle, and the cost is further reduced. If calculated according to the production and sales volume of 38 million in 2030, the average vehicle is 1 ton, which is 38 million tons, accounting for 5% or more of 2 million tons. Cars are very large users of carbon fiber applications.
Li Qingwen, Dean of the Automotive Evaluation Institute: The application of carbon fiber materials in the automotive industry has reached an accelerated stage.
The first concept that should be established is that the application of carbon fiber materials in the automotive industry has reached an accelerated stage. The application of various materials in the automotive industry has a process. Once an emerging material is applied to the automotive industry, the material industry will become a national economy. Big industry.
For example, the application of steel in the automotive industry has promoted the development of the steel industry, and the automobile industry has applied oil, making the petrochemical industry an industry that has a major impact on the world economy. The current Chinese automobile industry is moving towards electrification and electrification. The development has made the country's lithium battery industry flourish, and an excellent battery company represented by the Ningde era has emerged. China's auto parts companies have set up factories in Germany for the first time. So the conclusion is that as long as the automobile industry applies an important material, Important technology, this material or technology will form a huge industry.
We must realize that once carbon fiber materials are widely used in the automotive industry, carbon fiber materials will have a huge historical impact. Carbon fiber materials have spread from the defense industry and gradually radiated to the civilian sector. Forward-looking, in recent years, The automotive industry has begun to gradually apply carbon fiber materials. Carbon fiber materials have done many preliminary experiments in many of our vehicle manufacturers. Although these experiments have not all turned into results or industries, these preliminary preparations are very important. For example, Xingke Company I have done a lot of carbon fiber-related experiments with Great Wall Motor in the early stage. The application of any new materials takes time to verify. After a certain time inflection point, when all the conditions are available, it can be quickly transformed into results and applied to the market.
Yan Xigao, academician of the Chinese Academy of Engineering: The future of lightweight cars will start from the stringers
Xingke completed the first carbon fiber production line in Qiqihar and successfully applied it. This is of historical significance. From the perspective of materials science, it has now entered the era of composite material development. Taking resin-based composite materials as an example, it has special The functions and features of the equipment, that is, lightweight, high strength. At present, the high temperature performance can not be compared with ceramic or metal-based materials, but within a wide range, such as within 350 degrees can be tolerated.
The Chinese Academy of Engineering now has a considerable part of its efforts to invest in the research and development and application of carbon fiber composite materials. Many high-molecular materials have been applied in the field of automotive lightweighting. At present, the lightweight of automobiles has not yet touched the girders, but I think that in the future, the weight of automobiles may be Here, the longitudinal beam of the car accounts for a large proportion of the weight of the whole vehicle. For the lightweight of new energy vehicles, the energy density of the battery is increased, the battery volume is reduced, or the vehicle body is used, and the new high strength is adopted. Lightweight composite materials. The Chinese Academy of Engineering is also doing this work, such as flow batteries, fuel cells, super capacitors, etc.
Xu Jian, head of the 863 carbon fiber special expert group of the Ministry of Science and Technology: The electric bus with carbon fiber as the body structure can reduce weight by 5 tons.
After fifteen years of hard work, the actual production of carbon fiber in China has reached 26,000 tons, and the actual production in 2017 reached 8,700 tons. During 2011-2018, we mainly carried out research and development work in the fields of clean energy and modern transportation. The investment in the 863 project is 1.38 billion. We mainly complete the preparation process of high-strength carbon fiber.
During the 12th Five-Year Period, the special group has four main research and development directions, one is carbon fiber preparation and engineering technology; the second is carbon fiber composite chemical technology; the third is light energy preparation and manufacturing technology; the fourth is some new polymer material preparation technology. A total of 16 topics were scheduled for the final phase of the 12th Five-Year Period, 12 of which were from composite materials, light energy and new fibers.
In addition, during the 13th Five-Year Plan period, the special group made an experiment to build an electric bus with carbon fiber composite material as the body structure. The entire body structure of the bus was all carbon fiber. All the strength of the vehicle was designed domestically. The self-produced carbon fiber, this bus can still operate normally. The bus test vehicle has undergone a series of safety tests such as positive impact and rollover to ensure the safety requirements for passengers. After 2,000 kilometers of enhanced loop Experiment, the vehicle structure did not appear any abnormality. After the experts confirmed, the entire body weight loss from 13.5 tons to 8.5 tons, compared with the traditional steel structure body advantage.
Researcher of the Development Research Center of the State Council, deputy editor-in-chief of the (Economic Essentials) magazine He Yuxing: The 'black gold' of new technologies and new technologies has provided strong support for the transformation and upgrading of traditional industries.
High-tech, functional and low-cost carbon fiber and other new materials, new technologies, new technologies such as 'black gold', provide a strong support for the transformation and upgrading of traditional industries. In Qiqihar, I saw the concept of science, long-lost spirit, sufficient The strength of the hero, the heroic spirit of the following.
1, optimistic and positive attitude. There is a concept in the field of economics, called psychological expectations, optimistic, it may be good, bad, certainly bad. Intelligence is not passionate, we need to have passionate thoughts, not only passionate Thought, or tangible action. In technical terms, curing process, temperature, is an important condition and variable, you have the same passion as fire. China needs your enthusiasm!
2, scientific and correct direction. Automotive lightweight, intelligent heating, mold manufacturing, market space is wide. China's 38 million cars, if each car loses 5% weight, the energy-saving effect is huge. Just now, Du Duoshi said that the car has accelerated During the period, Dean Li Qingwen said, this is also the golden period of carbon fiber technology application. It will explode, and people who have worked hard to catch up with the materials will finally welcome the era that belongs to you. Academician Yan Xigao, now enters the compound In the age of materials, Xingke Group's production line has an epoch-making historical significance.
3, the strength of speaking. Qiqihar City is a heavy industry base, equipment manufacturing base, China's first headquarters, CRRC Group Headquarters, the three major military enterprises of the Weapon Industrial Group, here for the development of a solid foundation. Functionality and low Costs such as carbon fiber and new materials, new technologies and new processes have provided strong support for the transformation and upgrading of traditional industries.
The implementation of new technologies must have historical accumulation conditions. The localization of carbon fiber must first be localized in equipment and localization of basic research. Among the more than 500 major industrial products in China, more than 220 kinds of production are in the world. First, 115 Chinese companies have entered the list of the world's top 500. Under the innovation-driven strategy, in the past five years, the contribution rate of China's scientific and technological progress has increased from 52.2% to 57.5%, and the national innovation capability has risen from the 20th to the 17th in the world. The influence is done, not blown out.
4, the standard of benefiting the future. The structural structure of the composite material can be designed and affected by the process. The materials provided by different manufacturers may be different. The performance of the same material of the same manufacturer may also differ between different batch numbers. Standards and norms are very necessary. The right to formulate standards is the right to speak in the industry.
