汽车的历史不算太长,但汽车的发展却迅猛异常。专家们预测,21世纪将是汽车的社会。21世纪的汽车工业将出现全新的变化。材料轻型化目前,制造一辆汽车所需钢材约占整个汽车的65%、塑料占11%、铝仅占4%。为了促使汽车向轻型化发展,世界汽车工业正在悄悄地进行着一场“材料革命”。
The history of the car is not too long, but the development of the car is very fast. Experts predict that the 21st century will be the car’s society. The 21st century car industry will be a whole new change. Lightweight materials At present, the steel needed to make a car is about 65% of the entire car, the plastic is 11% and the aluminum is only 4%. In order to promote the car to light development, the world automobile industry is quietly carrying out a “material revolution.”
