Research progress and prospects of laser cleaning for CFRP: A review

CFRP is being widely used as a lightweight composite material in the aerospace field. At the same time, CFRP surface cleaning has gained attention. Laser cleaning technology, as an emerging surface cleaning method, has shown broad application prospects in cleaning CFRP surface resin, release agent, paint, etc. This paper firstly briefly reviews the traditional CFRP cleaning methods, and then focuses on the research progress of laser cleaning principles and the influencing parameters. Afterwards, the effect of laser cleaning on substrate performance is discussed. In particular, the damage characteristics and mechanisms of laser cleaning on composite substrates have received sufficient attention. Finally, the research challenges and trends in laser cleaning on composite materials are discussed. In conclusion, the review provides a reference to the research of laser cleaning on composites and promotes the promotion of laser cleaning technology in the aerospace field.
