Carbon fiber is a new type of fiber material with high modulus fiber with a carbon content of more than 95%.

　　If carbon fiber is to be popularized in the automotive field, two problems need to be solved, one is cost, and the other is recycling.As the production technology continues to mature, it is believed that the production cost of carbon fiber will continue to decrease.In addition to the production cost, manufacturers and governments also need to consider the recycling of carbon fiber parts. Compared with metal materials, the recycling of carbon fiber composite materials is more difficult.

　　Carbon fiber composite material has incomparable specific strength and specific modulus than other materials. The density is only about 1.6g/cm3, which is much lower than steel and aluminum. Applying it to the design of body and other parts can reduce the quality of the whole vehicle by 35%. For example, Volkswagen’s newly launched XL1 model with carbon fiber composite body and parts has a total mass of only 795kg. Combined with hybrid technology, fuel consumption per 0.9 kilometers is only XNUMX liters.
