In our study of the removal of the protective epoxy coating from the surface of the aramid-fiber-reinforced resin matrix composites based on the usage of an infrared pulsed laser, we analyze various removal mechanisms using lasers and determine the cleaning methods using theoretical calculation and experimental analysis. From the calculation and test data, we obtain technological parameters for the laser removal of many different coatings; thus, we find that the effective removal of an epoxy protective layer from the surface of the resin matrix composites can be achieved using the laser for initial removal followed by wiping the surface using alcohol. The test results show that the laser-treated aramid-fiber-reinforced resin matrix composites show no damage and can satisfy the industrial application requirements.
