Have you ever thought that the steel used to make car bumpers, seats, etc. will be replaced by glass fiber reinforced composite materials in the future? Today, the reporter learned from the Chongqing Municipal Science and Technology Commission that the "glass fiber for wind power equipment/engineering plastics" project "R & D and industrialization" passed the acceptance. In the next 5-10 years, many parts of the car will use a large number of glass fiber reinforced composite materials, which will reduce the weight of the car body and greatly reduce fuel consumption. It is understood that Chongqing International Composite Materials Co., Ltd. is mainly responsible for this project. At present, it has developed a complete set of continuous glass fiber technology for wind power equipment and a core technology of glass fiber chopped yarn for automotive engineering plastics. The core of these two technologies is a high-strength high-modulus corrosion-resistant glass fiber formula. It has applied for 8 invention patents and authorized 5, forming 4 enterprise standards.
 
What is high-strength, high-modulus, corrosion-resistant glass fiber He Jianming, deputy director of the General Engineering Office of Chongqing International Composite Materials Co., Ltd., said that glass fiber is an inorganic non-metallic material, which is commonly known as a new material. It has more advantages than traditional materials in terms of strength, elasticity, corrosion resistance and wear resistance. He Jianming said that traditional vehicle materials are basically steel, which also increases vehicle fuel consumption due to its high density and heavy weight. Compared with traditional materials, automotive composite materials made of glass fiber have lower density and weight. lighter. Under the same conditions, the weight of parts made of composite materials is only 1/3 of that of parts made of traditional materials.
 
However, due to the current application of this kind of composite material is less, and the cost is higher, the application of the whole vehicle is not much, the proportion of domestic vehicle parts is only 8%-12%, while foreign vehicles account for 20%-30%. However, according to the relevant person in charge of the Municipal Science and Technology Commission, replacing traditional steel with this composite material is an inevitable trend in the development of automobiles. It is expected that in 5-10 years, auto parts will use this material in large quantities. Such as car seats, bumpers, pallet brackets and other accessories, will abandon steel, the use of glass fiber reinforced composite materials.
