Abstract: Acoustic emission has the characteristics of real-time and continuous monitoring, and has achieved good performance in the research on composite damage mechanism. In this paper, the analysis methods and application status of acoustic emission technology in composite damage mechanism research are summarized. The advantages and disadvantages of parameter analysis method, waveform analysis method and pattern recognition are pointed out. Key technologies to be solved and future development trend are put forward in the investigation on composite damage mechanism, in order to lay the foundation for the improvement of acoustic emission in composite damage mechanism research.

Key words: acoustic emission, composite material, damage mechanism, parameter analysis, waveform analysis, pattern recognition
