Abstract

Abstract: Coating technology refers to the application of coating materials on the surface of structural parts to achieve its anti-corrosion, anti-friction, and thermal barrier functions. In recent years, it has been discovered through continuous in-depth research on coating technology that the application of coating materials on structural parts coatings can achieve good vibration damping effects and have little effect on the overall quality of structural parts. At the same time, the coating layer has the advantages of high temperature resistance, corrosion resistance and high hardness. Therefore, it has gradually become an emerging vibration damping method. The vibration characteristics of FRP coated with damping coating and butyl rubber damping layer were studied, and the frequency and damping loss factor of FRP in each mode after applying the above two damping materials were compared and analyzed. The results show that applying damping paint on the GRP plate can achieve a better vibration damping effect.

Key words: butyl rubber, damping coating, composite structure, vibration performance, modal strain energy
