Abstract: Carbon fiber reinforced carbon matrix composites (C/C) have the characteristics of low thermal expansion coefficient, corrosion resistance, thermal shock resistance, and wear resistance, which are widely used in military equipment, aerospace, automobile manufacturing and other fields. But it is difficult to achieve high precision machining of C/C composites by traditional processing technology. Laser processing technology has low requirements for the size, material and shape. It is easy to combine with other advanced processing technologies and has the characteristics that other methods do not have. This paper mainly reviews the preparation, application and processing methods of C/C composites, elaborates the mechanism and process characteristics of laser processing of C/C composites and the selection strategy of processing technology in different applications. Through the comparison of traditional processing methods and special processing methods, the problems and challenges faced by the processing of C/C composites are summarized, and the development trend of the combination of laser processing of C/C composites and other advanced manufacturing technologies is proposed.
