The future car is a green car adapted to environmental protection, so it is inevitable to mention the environmental awareness of the composite materials. Composite materials can improve material performance, prolong service period and enhance functionality, which are all favorable to the environment. However, it should be taken seriously and strive to overcome the problem of the regeneration of composite materials, so that the composite materials should be coordinated towards the environment.

The recycling of composite parts is very difficult, and it will have some adverse effects on the environment. For example, the most rapidly developing and the most applied polymer matrix composites are flammable substances. When burning, they will release a lot of poisonous gases and pollute the environment. When forming, the volatile components in the matrix will be diffused into the air, causing pollution. The use of composite materials is multi-component material which belongs to multiphase materials, crushing, grinding, melting and degradation of composite part is first decomposed into single material parts, but the decomposition process cost and regeneration of high cost, but also to restore the original performance is very difficult. Therefore, one of the main conditions of recycling is that parts are easy to disassemble, as far as a single material is concerned, and even composite materials should be used as few materials as possible. Based on the above principles, the applications of thermoplastic polyolefin elastomers, polypropylene foams and GMT reinforced panels will also increase significantly. On the contrary, the amount of thermosetting resins will be limited. At present, great progress has been made in the research of regenerative and degradability. In today's society, people's perspective has gradually shifted to the relationship between man and nature. The issue of environment and energy has become the key to the survival and development of every country in the world. With the continuous improvement of people's awareness of environmental protection and the introduction of environmental regulations, green cars have become the inevitable trend of the development of automobiles in the future. Therefore, how to make cars meet the requirements of environmental protection has mentioned the agenda of automobile manufacturers. As the mainstream of the development of automotive materials, composite materials will play a very important role in it.
