China Chongqing News, Feng Xuexun, Secretary-General of the Chongqing Material Society, said that Chongqing's magnesium alloy and glass fiber materials technology ranks first in the country in terms of research and industrialization.
After two years of maintaining the automobile safety of magnesium alloys, Changan Automobile is expected to use magnesium alloy bumpers, which will greatly enhance the car's anti-collision ability. Recently, Zhang Dingfei, deputy director of the 2008 International Materials Conference session and the dean of the School of Materials Science and Engineering of Chongqing University, introduced that the advanced material of Chongqing has made a breakthrough in the application of automobiles.
It is understood that the National Magnesium Alloy Materials Engineering and Technology Research Center based on Chongqing University is working on this research. Magnesium alloy has the characteristics of light weight and small vibration. After collision, it can absorb a large part of energy. If it is made into a car bumper, the driver and passenger can be well protected after a crash. At present, magnesium alloy bumpers have been sampled and have passed the test of Volkswagen.
Zhang Dingfei said that as one of the representatives of advanced materials in Chongqing, more than 40 magnesium alloy products have been produced on a large scale and have been applied to more than 2 million motorcycles and 50,000 Changan mini vehicles.
At the International Material Conference for Fiberglass Manhole Cover at the Sewerage Exchange, the person in charge of Chongqing International Composites Co., Ltd. introduced that some municipal departments in Chongqing had contacted them and planned to replace the fiberglass manhole cover in the sewer area.
It is understood that this company is used for pipe manufacturing is a kind of glass fiber named ECR, which is used for various types of corrosion pipes with excellent chemical resistance. "Compared with metal pipes, glass fiber mixed resin pipes are more rigid and more suitable for sewage disposal." The person in charge also said that "glass fiber manhole covers are not only easy to install, but also prevent the occurrence of stealing and trafficking in manhole cover."
It is reported that glass fiber technology can also be applied to automobiles to replace steel. "The more glass fiber materials are used, the lighter the vehicle's weight will be, the less fuel consumption will be consumed, and the goal of energy saving and emission reduction while driving will be closer to us."
