Abstract: In recent years, the research progress of oxidation treatment, surface coating method, plasma treatment method on CF body performance and CFRP mechanical properties at home and abroad are reviewed, and the mechanism and modification of CFRP mechanical properties modified by different treatment methods are analyzed, Sexual effects, advantages and disadvantages. Pointed out the problems in domestic and foreign research in recent years and future development trends, promote the further application of high-performance CFRP in the aerospace field, and provide complete data information and theories for future researchers to further develop and produce new composite materials and improve the comprehensive performance of CFRP in accordance.
