Energy Saving "plastic car" era coming – Auto Door Controller – Filter
The industry believes that "plastic car" era is approaching. The late 80s of last century to the late '90s, "all-plastic car" concept has been a sensation in the domestic auto industry. Beijing, Shandong, Zhejiang, Chongqing and other places of the automobile manufacturers, are produced all epoxy fiberglass body. But basically hand-paste system, grades to be improved. Dongfeng Bus Company using hand lay-up production of a high-speed passenger craft all fiberglass body, each consume about 250 kg of glass, steel; Beijing Auto Glass Steel Co., the production process using hand lay-cab, full-body weighs just 600 kg.
Application of Automotive Materials
With the rapid development of science and technology, the modern automobile manufacturing material composition, great changes have taken place, the proportion of high-density material down, low-density material has increased greatly, it can be said, from the 90's, the automotive materials to Lightweight, save resources, the direction of high performance and high functionality. Nowadays, the automotive industry has come the era of globalization, vehicle manufacturers can hardly be completed within one country, all of the automotive industry procurement, must rely on their own production capacity from the past, turning in the global allocation of resources. Auto Parts Global Sourcing in the context of the development of China's auto parts industry, the spring is coming. The current resource and environmental factors by the bottle pre-constrained, lightweight, energy-efficient components has been the international automotive industry research. Among them, the development of high strength lightweight high performance of new lightweight materials and design of the new structure, will certainly be the best choice for auto parts materials. FRP composites have high strength due to significant design freedom, it is not rusty, molding technology and good nature, as automobile Plastic in the ideal processing materials. At present, more and more models using epoxy resin-based composite parts, but also as Plastic in an ideal material for automotive sector has been gradually recognized, although hand lay-up process is still in production in some automotive components field is still dominated, but SMC, RTM, GMT, etc. Application of advanced materials and processes to promote rapid.
Currently the world's annual output has reached civil composite materials more than 550 million tons, annual output value of 130 billion U.S. dollars more than that if Europe and America's military aerospace products included high-value, the output value will be even more amazing laid. Globally, the world production of composite materials mainly in Europe and the United States and East Asia. Composite materials in recent years, Europe and the United States continued to grow both production and demand, while in Asia the Japanese economy has been sluggish due to the slow development. However, mainland China, especially China, the rapid development of composite materials industry. According to PPG, Inc., 2000, of composite softball in Europe about 32% market share, the total annual output of around 2 million tons. Meanwhile, the U.S. composite materials in the 20th century is the annual growth in 90 years, average annual growth rate of U.S. GDP growth of about 2 times, 4% to 6% range. In 2000, the United States, the composite growth rate of 4% of annual output of 170 tons. U.S. composites market, mainly due to the steady growth of car use composite materials is increasing rapidly. Extensive use of composite materials in the car and make the U.S. auto re-emergence in the global market. Asia in recent years the development of composite materials and the overall political and economic change is closely related to the countries share a great deal. Mainland China since the reform and opening up, the rapid development of composite materials, the average annual growth rate of 8% ~ 9%, with China Taiwan Area circuit board manufacturing base migrated to the mainland, the Chinese mainland market will be more composite materials development, China Composites 2006, the total output up to 1.85 million tons.
