Temperature and Frequency Dependences of Dissipative Properties of Rigid Vibration-Damping Coatings

Resumo

Abstract—A study of the temperature and frequency dependences of the mechanical loss factors and elastic moduli of polymeric materials allows one to calculate the efficiency of vibration-damping coatings on substrates of metals and rigid composites under specified operating conditions. The calculated and experimental data for different compositions of vibration-damping materials are compared. The studies are performed using polymer compositions on the basis of modified epoxy resins and reinforcing fillers.
