Beschreibung
Zusammenfassung:	The present invention provides a method and device for laser pretreatment of surfaces of a resin matrix composite, and relates to the technical field of laser processing. The method for laser pretreatment of surfaces of a resin matrix composite provided by the present invention includes the following step: scanning surfaces of a resin matrix composite with ultraviolet lasers, wherein a wavelength of the ultraviolet lasers is 355 nm. The present invention utilizes the ultraviolet lasers to perform laser pretreatment (including surface cleaning, activation and roughening) of the surface of the resin matrix composite, and limits the wavelength of the ultraviolet lasers to 355 nm. The present invention fulfills the aim of laser cold processing (at a temperature of not higher than 45°C), avoids thermal aggregation from burning the resin matrix composite, and has the advantages of high pretreatment efficiency, high quality, simple operation, and environmental friendliness.
