Glass fiber replaces steel to reduce fuel consumption


Have you ever thought that the steel used to make bumpers and seats for automobiles will be replaced with fiberglass reinforced composites in the future? According to the Chongqing Municipal Science and Technology Commission, the project “Research and Industrialization of Glass Fiber for Wind Power Equipment/Engineering Plastics” passed the acceptance test. In the next 5-10 years, many parts and components of automobiles will use glass fiber reinforced composite materials, and the weight of the body will be reduced, and the fuel consumption will be greatly reduced.

At present, it has developed the core technology of glass fiber chopped yarn for continuous glass fiber complete sets of wind power equipment and automotive engineering plastics. The core of these two technologies is high strength. The high modulus corrosion-resistant glass fiber formula has been declared 8 invention patents and 5 authorized, forming 4 enterprise standards.

What is high strength and high modulus corrosion resistant glass fiber? Any Jianming, deputy director of the Chongqing International Composite Materials Co., Ltd., said that glass fiber is an inorganic non-metallic material, also known as a new material, which has advantages over traditional materials in strength, elasticity, corrosion resistance and wear resistance. .

He Jianming said: The traditional vehicle materials are basically steel. Because of its high density and heavy weight, it also increases the fuel consumption of automobiles. The composite materials made of glass fiber are smaller and lighter than traditional materials. light. Under the same conditions, the weight of parts using composite materials is only 1/3 of that of traditional materials.

However, due to the current application of this composite material, and the high cost, there are not many applications on the whole vehicle. 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, the replacement of traditional steel with this composite material is an inevitable trend in the development of automobiles. It is expected that in 5-10 years, automotive materials will use this material in large quantities. For example, car seats, bumpers, tray brackets and other accessories will abandon steel and use fiberglass cloth reinforced composites.
