Application status of the hottest composite materi

With the rapid development of China's automotive industry, the burgeoning automotive parts industry shows attractive business opportunities, and composites, as the cutting-edge technology of new materials, will become the dominant industry in this emerging industry. What is the current application of composite materials in China's auto parts market

what is the situation of the application of composite materials in the field of auto parts in China? It is an issue of great concern to Chinese auto people, as well as to the majority of Chinese auto lovers and consumers. With such questions, the author recently visited the 2010 Beijing International Auto Parts Exhibition held by Beijing International Exhibition

compared with the previous Beijing auto parts exhibition, this exhibition in 2010 can be said to be the largest in history, which also shows that China's status as the world's largest auto consumption country can no longer be ignored. However, after walking through 10 exhibition halls, the author also found a problem. The application of composite materials in auto parts, mainly auto body panels, is actually very few. What's more, when the author asked the staff on the booth about some questions about composite materials, many people didn't understand the concept of composite materials at all, and some people didn't know that FRP was composite materials

it can be seen that the application of composite materials in the automotive field has always been following the trend abroad, but it is only some ardent expectations of the domestic media. Although FRP composites have been applied in China's automotive field, more and more Xindu can deal with their favorite composites abroad, such as carbon fiber and natural fiber, which are constantly being applied to the automotive field. FRP will gradually become a thing of the past, because more innovative composites have better properties than FRP. In China, the hand paste molding process is still dominant in the field of producing auto parts, and the advanced competitive pattern of SMC, BMC, RTM, GMT and so on is also in the process of comprehensively reshaping the application of materials and processes is still very lacking

the Copenhagen conference in 2009 pushed the "low-carbon economy and new energy" to the focus of attention of all countries in the world. China has also made a commitment to this. By 2020, China's carbon dioxide emissions per unit of gross domestic product (GDP) will be 40% - 45% lower than that in 2005. This is indeed a goal that requires efforts to save energy and reduce holdings. As a major auto consumer, the production and use of new energy vehicles in China will become the development trend in the future, which gives an opportunity for automobile lightweight. At the same time, it is also a huge market for composite auto parts to develop by turning raw starch into thermoplastic starch. Therefore, Chinese auto people should seize this market opportunity, but the situation I saw at the 2010 Beijing International Auto Parts Exhibition is not at all such a situation. Many booth service personnel do not even know the basic awareness of composite materials

having said so much, in fact, automobile enterprises also have their own difficulties. The use of emerging carbon fiber and other composite materials is bound to increase the cost of finished vehicles. Can China's market purchasing power bear it? It is not difficult to think that 1projet MJP 5600 also has a new 3D sprint 2.5 software image, which will be difficult, so the strong support and subsidies of the government are also more critical
