The four traditional manufacturing processes of automobile stamping, welding, painting, and final assembly may disappear on a certain day. At that time, the car only needs to be bonded with composite materials.
Some returnee automotive technology experts say that innovative applications of composite materials can subvert the traditional automotive industry. Experts even assert that the lightweight of the automotive industry can be compared to the industrial revolution brought about by steam engines.
In the innovative application of composite materials, the launch of the BMW i3, whether it is the automotive industry or the material session, is full of praise. Many people in China have visited the BMW i3 factory and saw that the entire production line is very different from the traditional car production line. The body and frame are made of carbon fiber once. Therefore, it is predicted that not only the traditional four major processes of automobiles will disappear, but even the process of painting can find changes. For example, cars can directly adopt the color of composite materials, just like the current linen clothes.
The BMW i3 is an introduction that tells people that traditional car craftsmanship does not necessarily go on. If China does not actively study the innovative application of composite materials and does not actively carry out the pre-technical reserves, once BMW or other vehicle companies break through the carbon fiber cost and molding cycle problems, the composite materials will be widely promoted, and we will be smashed. When you are behind, you are really out. It is understood that foreign countries from the government, vehicle companies to material suppliers have attached great importance to the study of carbon fiber. China is seriously lagging behind Japan, Europe and the United States in raw materials, especially carbon fiber. It is reported that more than half of the current carbon fiber precursors are controlled in Japan. Fortunately, many material suppliers in China are now paying attention to this field. Last year, Kangde Investment Group Langfang Carbon Fiber Project put into production of high-performance T700 grade carbon fiber raw yarn, with a planned production capacity of 5,100 tons and a first-phase production capacity of 1,700 tons. It is expected to be trial-produced in the third quarter of 2015 and officially put into production in the fourth quarter. The products are mainly used to build new energy. Automotive parts. According to industry experts, BMW's Langfang carbon fiber project will use BMW's technology to produce new energy vehicle carbon fiber components to enter BMW's supply chain system due to its own insufficient production capacity.
In October 2014, Zhong Yu, Chairman of the Kangde Investment Group, visited Premiere with Premier Li Keqiang and signed an investment cooperation agreement with the German Goldman Sachs Group on the “Industrialization Project of Carbon Fiber Vehicle Parts and Components for New Energy Electric Vehiclesâ€. The Kangde new carbon fiber project is supported by the national strategic capital, indicating that the country has realized that the wide application of composite materials in automobiles is the future development direction.
If the car body and the frame use composite materials instead of steel, it will be a revolutionary change. However, it is not rumored that composite materials such as carbon fiber are difficult to popularize in the short term. We look forward to this revolutionary change and even subversion, but the most urgent task is to lay the foundation for the opportunity.
