Abstract: The definition of plasma was introduced. The principle and application on fiber surface preparation of plasma technology were briefly introduced. At the same time, the research and development of plasma technology on matrix surface preparation domestic and overseas in the past years were summarized. There were several important factors during the plasma preparation procedure, such as electric power, processing time, gas types and processing pressure. The characterization method, such as mean surface roughness, contact angle (water) and shear strength, fatigue mode after bonding were also introduced in this work. Finally, the potential difficulties of domestic plasma technology were summarized.

Key words: plasma, composite, matrix surface, surface preparation, bonding
