1. high-performance plastics become SUV lightweight materials
Plastics, especially high-performance plastics, are playing an increasingly important role in the automotive industry. The lightweight nature of plastics makes vehicles more energy efficient during use. It is estimated that every 10% reduction in vehicle weight will reduce fuel use by 5%-7%.
Tesla's super factory in Shanghai will be put into use in the near future. As the leader of new energy vehicles, Tesla plays an important role in the Chinese market with its own technical advantages and brand influence. At the same time, Tesla also announced cooperation with Space X company and invested more energy in the research and development of new materials.
Recently, Tesla announced that it will use synthetic materials in the new Model S and the upcoming Model Y. Among the high-performance plastics for vehicles, polypropylene (PP) materials account for a high proportion of plastic usage, which has reached about 40%.
2. automotive engineering plastics will replace more metal parts
Developed countries use the amount of plastic used in automobiles as an important indicator to measure the level of automobile design and manufacturing. At present, Germany uses the most automobiles, accounting for more than 15% of vehicle materials. In addition to the British Land Rover, Lamborghini, Mercedes-Benz SLR, BMW I-Series and many other models use more advanced automotive engineering plastics on a large scale. Even some experts predict that the innovative application of new materials in the future may subvert traditional cars.
Smog, energy saving and emission reduction and more stringent fuel consumption regulations, domestic car companies have spared no effort to develop automotive lightweight technology. As we all know, the lightweight of automobiles is mainly reflected in the optimization design of automobiles, the application of alloy materials and non-metallic materials, which in turn are the lightweight weight reduction of automobiles by 10% ~ 15%, 30% ~ 40%, and 45% ~ 55%. Zheng Kai told reporters that non-metallic materials such as engineering plastics have obvious "weight reduction" effects, and their main function in automobiles is to make automobiles lightweight. At present, more and more automobile parts begin to use engineering plastics instead of metal parts.
The application of engineering plastics for 3. vehicles is increasing year by year.
"The proportion of general plastics is 0.9~1.6, and the proportion of glass fiber reinforced composites will not exceed 2.0, while A3 steel is 7.6, brass is 8.4, and aluminum is 2.7. This makes plastic a lightweight material for cars. The use of plastics can reduce the weight of parts by about 40%, and its cost can also be greatly reduced.
Replacing metal parts with plastic parts can not only reduce vehicle weight, reduce fuel consumption and emissions, but also improve the power, comfort and safety of the car. Therefore, it is widely used in automobile power and chassis systems, interior and exterior decoration parts, and automobile electronics. And other parts.
