According to Chongqing, China, fengshixun, Secretary General of Chongqing society of materials, said that the technology of magnesium alloy and glass fiber materials in Chongqing ranks at the national level in research and industrialization. After two years of safety, Chang'an automobile is expected to use magnesium alloy bumper, which will greatly strengthen the anti collision ability of the car. Recently, Zhang Dingfei, the host of the 2008 International Materials Conference and vice president of Chongqing University College of materials science and engineering, introduced that the application of this advanced material in Chongqing has made breakthrough progress in automobile. It is understood that the national magnesium alloy material engineering technology research center, which is 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 bumper, the driver and passenger can get good protection after the collision. At present, magnesium alloy bumper has been made samples and has passed the test of Volkswagen in Germany. Zhang said that as one of the representatives of advanced materials in Chongqing, more than 40 kinds of magnesium alloy products have been produced on a large scale and have been applied to more than 2 million motorcycles and 50000 Chang'an micro cars. At the International Conference on glass fiber cover for sewer, the head of Chongqing International composite material Co., Ltd. introduced that some regional municipal departments in Chongqing have contacted them and plan to replace glass fiber covers at the sewer outlets in the area. It is understood that the company is used in the pipeline manufacturing is a kind of glass fiber called ECR, which is used for various corrosion pipes with excellent chemical resistance“ Compared with metal pipes, glass fiber mixed resin pipes have stronger hardness and are more suitable for sewage discharge. " "Glass fiber covers are not only easy to install, but also avoid theft and trafficking," the person in charge added It is reported that glass fiber technology can also be used in cars, instead of steel“ The more glass fiber materials are used, the lighter the vehicle weight will be, the less fuel consumption per unit, and the goal of energy conservation and emission reduction will be closer to us when driving. " The person in charge introduced.
