Composite material: make the car light and safe

Automobile lightweight technology has long been familiar to the chemical industry. In the era of energy saving, it has become a consensus in the industry to apply resin, rubber, carbon fiber composite materials and other materials to the body or parts of the car to reduce the weight of the car. For new energy vehicles, this is even more important, because the power battery will increase the body quality.

One of the major problems faced by the electric vehicles on the road is the short battery mileage. The E6 electric vehicle launched by BYD, a leading domestic new energy vehicle enterprise, has a long endurance of 300 kilometers as its selling point, but it is only a good value obtained under the condition of comprehensive condition test, which is still far behind the traditional fuel vehicles. Therefore, while improving the battery performance, it is very important to reduce the body mass and energy consumption per kilometer.

According to the plan, it is necessary to break through the common technologies and process technologies such as body materials and structural lightweight in the process of industrialization, which will promote the development of automotive composite materials. With the continuous emergence of new chemical materials and the upgrading of production technology, more and more automobile parts can be made of light materials. In addition to the multinational companies that actively layout the Chinese market, domestic enterprises have turned their attention to this field. In order to reduce the body quality of alternative materials, the chemical related materials to ensure the driving of new energy vehicles will usher in new opportunities.

In addition, the battery itself is also one of the ways to reduce the load of new energy vehicles. According to the planning, by 2015, the specific energy of the power battery module will be more than 150 Watt hours / kg, and the power density of the electric drive system will be more than 2.5 kW / kg. It will be a new task for chemical industry to develop new battery materials and make lighter batteries run longer.
