At present, along with the rapid development of China's auto industry, the emerging auto parts industry shows attractive business opportunities. As a new material, cutting-edge technology, composite materials, especially high-performance epoxy-based composite materials, will surely become the emerging industry. Industry-led. At the China Auto Parts Industry Cluster Expert Forum held in Wucheng, Shandong, the industry participants once again confirmed this trend.
Experts believe that the era of "all-plastic cars" is approaching. Sun Bohuai, chairman of the China National Machinery Industry Enterprise Management Association, said that the current era of globalization of the automotive industry has come, it is difficult for auto manufacturers to complete the entire procurement of the automotive industry within a country, and will inevitably shift from relying on its own production capacity in the past to a global scale. Configure resources. Under the background of global procurement of auto parts, the development of China's auto parts industry has come in the spring. At present, due to bottlenecks of resources and environmental factors, lightweight, energy-saving components have always been the research direction of the international automotive industry. Among them, the development of lightweight, high-performance, new materials with higher strength and the design of new lightweight structures will inevitably become the best choice for auto parts materials. According to experts from the China Epoxy Resin Industry Association, epoxy glass fiber reinforced plastic composites have become the ideal processing materials for plastics steels in the automotive industry due to their obvious advantages of light weight, high design freedom, non-rusting, and good molding processability. At present, more and more models in our country use epoxy resin-based glass fiber reinforced plastics/composite parts, and as an ideal material for plastic substitute steel, it has been gradually recognized by the automotive industry, although the hand lay-up process is still producing certain automobiles. The area of ​​parts and components is still dominant, but the application and promotion of advanced materials and processes such as SMC, RTM, and GMT are very fast.
From the late 1980s to the late 1990s, the concept of "all-plastic cars" was once a sensation in the domestic automobile industry. Manufacturers in Beijing, Shandong, Zhejiang, and Chongqing have all produced glass-fiber-reinforced epoxy glass bodies. However, it is basically hand-made and the grade needs to be improved. Dongfeng Bus Company adopts a hand-paste forming process to produce a full-glass FRP car body for high-speed passenger cars, each of which consumes 250 kg of glass-fiber reinforced plastics such as epoxy; Beijing Automotive Glass Fiberglass Co., Ltd. uses a hand lay-up molding process to produce the cab, with a full body weight. Only 600 kilograms. Epoxy glass fiber reinforced plastics/composites have been widely used in cars, passenger cars and trucks, such as car bumper bumpers, roofs, door doors, front frames, engine hoods and other exterior parts, as well as car lights. Reflectors, battery trays and other components are widely used. The front panel, left and right corner panels, and left and right spoilers of the Volvo heavy truck produced by Jinan Heavy Duty Truck Group are all manufactured using SMC or RTM. The masks, wind deflectors, and front under-protection surfaces of the Yellow River heavy-duty truck improved models are made of SMC or hand-paste FRP materials. This is mainly due to the advantages of composite materials such as saving weight, saving fuel, high product integration, high design freedom, and low investment costs.
At present, a number of auto parts production bases have been established throughout the country. There are only a few gathering belts such as Qingdao and Dezhou in Shandong. “The country’s first glass fiber reinforced plastic county†in Wucheng County, Shandong Province, started early in the industry and currently has more than 1,300 glass fiberglass production enterprises, employs 90,000 people, and has an annual output of 350,000 tons, accounting for about 30% of the country’s total production. The base material is mainly epoxy resin. In 2004, it achieved a sales income of 9.8 billion yuan. Among them, the epoxy glass FRP automotive exterior parts developed and researched by Xinming Company have obtained the exclusive rights to supply “Steyr King†and “HOWO†automobiles produced by China National Heavy Duty Truck Group and Volvo CNHTC.
Composite parts will become a trend. The rapid development of China's auto industry has brought potential business opportunities for epoxy glass fiber reinforced plastics/composites. Wu Kai, general manager of Beijing Automotive Glass & FRP Co., Ltd., said: “One of the distinguishing features of today’s car development is the diversification of products and the rapid development of new products. New electronic and electronic technologies, computer control technologies, and new process technologies continue to enter the automotive industry. The increasing demand for chemicals has resulted in faster and faster vehicle renewal. It is crucial for the development of the automotive industry to realize lightweight vehicles, reduce fuel consumption, increase payload, and improve transportation efficiency.†said expert from the China Epoxy Resin Industry Association. In recent years, epoxy composites, the cutting edge of new materials, have gradually replaced metal products in auto parts and achieved more economical and safe results. At the China Auto Parts Industry Cluster Expert Forum held in Wucheng, Shandong, Manfred, an expert from Germany's BYK Company, was convinced. For example, he said that Ford Motors currently integrates the original 11 metal parts by changing the hood cover of the automobile engine into a molded part, and the annual output of this Ford vehicle is 200,000. Production practices and scientific research have shown that epoxy glass fiber reinforced plastic/composite materials are relatively scientific and ideal new automotive component materials. In the future, it will play an important role in the development of new vehicles that are energy-efficient, environmentally friendly, rapid retrofitting, and small batch production. According to statistics, the glass-fiber reinforced plastic/composite materials used in each automobile in Europe and the United States in the 1990s reached 60 kg to 80 kg. The base material is basically epoxy resin, and the glass fiber reinforced plastic used in each automobile in China is currently used. / Composites average less than 10 kilograms.
