Under the "dual carbon" goal, the key to achieving carbon emission reduction in the supply chain is the adoption of new technologies, new materials, and new processes, from the development and design of auto parts to research and trial production, from mass production to raw material selection, almost every link Both can deeply tap the potential and reduce carbon emissions. Therefore, the application of new materials in automobiles is of great significance to the development of the automobile industry.
Currently, automotive body materials can be roughly divided into two categories. The first category is metal materials, including heavy metal materials such as steel plates and cast irons, as well as light metals such as aluminum, magnesium, and titanium and its alloy materials, foam metals, etc. Materials; The second category is non-metallic materials, including engineering plastics, fibers, resins, glass, rubber, non-metal foam materials, and non-metal composite materials. With the development of automotive technology, composite materials and nanomaterials will be widely used in future automotive materials.
Under the general trend of global energy saving and environmental protection, the use of automotive materials also revolves around these two trends, and is developing in the direction of lighter weight-more environmentally friendly, low VOC-healthier, low odor-and more comfortable.
First of all, when the fuel consumption pressure of automobiles is getting tighter and the cruising range needs to be made up urgently, lightweighting that can alleviate these two pressures has gradually become an important label for new cars. Although automobile lightweighting is mainly composed of structural lightweight design and material lightweighting, it is currently mainly dependent on material lightweighting. Therefore, car companies and component companies focus more on the development and application of lightweight materials. In the "Energy-saving and New Energy Vehicle Technology Roadmap", the application of lightweight materials is listed as one of the important technology paths for lightweighting.
Secondly, in terms of environmental protection, low-VOC materials are strictly controlled from molecular design, polymerization process, processing technology and other links, which greatly reduces the small molecules that are easily emitted in the material, and makes the material more stable, less volatile, and achieves low VOC Requirements. In car interiors, many parts will use low-VOC materials, such as center control panels, door panels, shifter covers, and so on. Therefore, low-VOC materials play a role in safeguarding the lives and health of drivers and passengers.
After years of rapid growth, China's automobile industry is entering a new period of industrial transformation and technological upgrading. Driven by the "double points" regulations and the new energy vehicle industry policy,Automotive materials also usher in new development opportunities. The traditional steel-based automotive material structure is developing towards the trend of mixed application of steel and aluminum, all-aluminum body, plastic composite materials and magnesium alloy .
In recent years, automobile materials represented by body panels and body frames are undergoing a profound change. The proportion of non-ferrous metals and their alloys, powder metals and composite materials in automobiles is rapidly increasing, and new materials have emerged The trend of transitioning from simple parts to complex structural parts and gradually replacing traditional materials. The use of new materials not only helps to improve the technical performance of automobiles, but also makes it possible to realize many new designs and new technologies in industrial production.
However, in the development of new automotive materials, there are also many factors that restrict their large-scale application. Cost and price are the first to bear the brunt, and technological progress cannot be achieved overnight. So, how can we solve these problems?
The 2021 China Automotive Supply Chain Conference to be held in Chongqing on October 15-16 will set up a special forum on the topic of "New Developments in Automotive Materials". Focusing on the high-quality development of the automotive industry, industry experts, scholars and corporate executives will be invited to discuss together The new dynamics and technological development trends of automotive materials aim to promote the integration and innovative development of the automotive materials industry.
The theme forum of "New Developments in Automotive Materials" will be held on the second day of the conference, in the morning of October 16, hosted by Professor Yu Muhuo of Donghua University and deputy director of the State Key Laboratory of Fiber Material Modification People, by then, two academicians Jiang Shicheng and Ding Wenjiang from Chinese Academy of Engineering will focus on "high-performance fibers and their applications in automotive lightweighting" and "development status and trends of lightweight alloys for automobiles". Give a speech on the subject.
The technological innovation of traditional materials and the technological breakthrough of new materials will all be discussed in this theme forum. Beijing University of Chemical Technology Vice President and Professor Zhang Liqun will give a keynote speech on the development status and trends of "green low-carbon rubber materials for next-generation tires",Professor Yu Muhuo, who also serves as the host, will also give a keynote speech on " Carbon Fiber Composite Material's Key Technology Progress in the Application of Mass Production Vehicles", a speech by Central South University Professor and Chairman of Hunan Shixin New Materials Co., Ltd. Xiao Peng The topic is "The development of carbon-ceramic composite brake discs for passenger cars and product standards and testing methods". Zhou Yinghui, director of the Global Innovation Center for Automotive Materials of Kingfa Technology Co., Ltd., gave a speech on "Development of Modified Plastics for Vehicles under the New Situation "Trends", and Xiong Fen, manager of the non-metallic materials room of the Quality Verification Center of Dongfeng Motor Group Co., Ltd., will analyze the "development and application of automotive material technology under the dual-carbon background" from the perspective of vehicle companies.
Faced with the opportunities and challenges of new materials in the high-quality development of Chinese automobiles, the theme forum also arranged a round table dialogue, inviting Shanghai Jiao Tong University researcher, Jiang Haiyan, deputy director of the National Engineering Research Center for Light Alloy Precision Forming, SAIC Group Yin Jianwei, System Manager of Passenger Vehicle Branch of Co., Ltd., Jiang Yang, Deputy General Manager of Trina Solar Technology Group Co., Ltd., Gao Xiaoyan, Head of Automotive Business of Trina Solar Co., Ltd., and experts and scholars such as Xiong Fen and Zhou Yinghui, as well as from complete vehicles Representatives of enterprises and parts and components gathered together to brainstorm and collide ideas around the application and prospects of new materials such as carbon fiber composite materials, light alloys, high-strength steel, engineering plastics, battery materials, and hydrogen energy materials.
On October 16, come to the 2021 China Automotive Supply Chain Conference and pay attention to the "New Developments in Automotive Materials" theme forum. The dry goods are full, and the industry will surely live up to expectations.
