Abstract: Carbon fiber composite is one of the excellent lightweight materials with the advantages of low density, high modulus and high specific strength. The application situation of carbon fiber composite materials in automobiles at home and abroad in recent years. It is found that although carbon fiber composite materials have excellent lightweight effect, there are many problems such as high cost, complex process and low efficiency. At present, it is mainly suitable for application in high-end models at home and abroad. In order to explore the application trend of carbon fiber composites in automobiles, this paper analyzed the application situation of carbon fiber composites in automobiles at home and abroad in recent years. It is found that although the lightweight effect of carbon fiber composite was excellent, but it was mainly suitable for application in high-end vehicles for high cost, complex process and low efficiency. At present, it is mainly suitable for application in high-end models at home and abroad. Because carbon fiber composite had a dazzling appearance, it was popular with young people. The development of carbon fiber composite exterior parts in the form of "sports kit" would be the main growth point of the application of carbon fiber composite in automobiles in the future.
