Elastomer damping materials have unique dynamic viscoelastic behavior and are widely used in many fields such as vibration damping and noise reduction.In practical applications,elastomer damping materials of-ten face the problems of narrow effective damping temperature range and low loss factor.Widening the effective damping temperature range and increasing the loss factor are the main directions for the development of high performance elastomer damping materials.Based on the damping mechanism of elastomer damping materials,this paper expounds the influence of molecular structure,operating temperature and vibration frequency,and e-lastomer composition system on the damping performance of elastomer damping materials.The modification methods of elastomer damping materials and the latest research progress in recent years are also introduced.
