摘　　要：未来汽车什么样可以简单地描述为:用绿色电驱动,所谓绿色电就是水电、太阳能、风电、核电等;无人驾驶,即数字化全自动化操控行驶,可在城市空中飞,可在城市河面滑行。当前的新能源电动车是用铝材制造的,铝材零部件质量占50%以上;2030年前后复合材料用量可占20%,铝材用量会相应地下降;除非研制成功了一批新型的高性能的铝合金,否则2040年以后复合材料会成为主要的汽车材料。The future of the car can be simply described as:driven by the green electricity.The so-called green electricity is hydropower,solar,wind and nuclear power and so on.Unmanned,that is,digital and fully automatic control driving,can fly in the city air and glide on the city river surface.The current new energy electric vehicles are made of aluminum and aluminum parts account for more than 50%of the whole mass.Around 2030,the use of composite materials can account for 20%,the percentage of aluminum will decline accordingly.Composite materials will become the main automotive materials after 2040,unless a new batch of high-performance aluminum alloy is successfully developed and is enough to main?tain its leading position in the new energy automotive materials.
