The biggest advantage of carbon fiber is that it weighs less than a quarter of steel and is lighter than aluminum, making it the perfect material to achieve "lightweight". 30 percent lighter than aluminum and 50 percent lighter than steel. If all the steel parts of the car were replaced with carbon fiber composite materials, the weight of the car could be reduced by 300 kilograms. Carbon fiber is 20 times stronger than iron, and it is the only substance that does not lose strength at high temperatures of 2000℃. Excellent impact absorption capacity is 4-5 times that of ordinary metal materials
