(Summary description)In certain applications, it is necessary to connect multiple composite parts into a whole through adhesive bonding process. In this process, it is difficult to complete the bonding process between composite parts by adhesive coating, because the surface of the composite material has dirt, is smooth or is chemically inert. Using the method of physical grinding, the surface roughness of the composite parts is increased, so as to improve the bonding performance between the composite parts. However, this method is difficult to achieve the purpose of uniformly increasing the surface roughness of the parts while producing dust pollution to the environment, which is easy to cause the deformation and damage of the surface of the composite parts, and then affect the performance of the adhesive interface of the parts. Therefore, the simple and easily controlled plasma technology can be considered to effectively clean the surface contaminants of composite material products, and improve the surface physical and chemical properties, so as to achieve a good bonding effect. Application of plasma cleaning technology to clean composite material, whether it is used to improve the interface of the composite performance, improve the wettability on the surface of the liquid molding process of the fibers in the resin to, or used to clean up the dirt layer on the surface of the parts, to improve the coating performance, or to improve the bonding performance between multiple parts, its reliability mainly depends on the low temperature plasma on the improvement of material surface physical and chemical properties, or used to remove the weak interface layer, or used to increase the roughness, improve the chemical activity, thus improve the infiltration and bonding performance between the two surfaces. With the growing maturity of low-temperature plasma technology and the development of cleaning equipment, especially atmospheric on-line continuous plasma equipment, the cleaning cost is constantly reduced and the cleaning efficiency is further improved. Plasma cleaning technology itself has the advantages of convenient processing of various materials, green and environmental protection. With the gradual improvement of people's understanding of fine production, the application of advanced cleaning technology in the field of composite materials will be widely promoted.
