Polymer restrained damper (heat-resistant reinforced patch) material is an effective measure to reduce vibration and noise of thin-walled structures. The restrained damper layer is laid on the thin-walled plate of vibration and sound production. By restraining the amplitude of bending vibration, the noise reduction ability is improved and the radiated noise is reduced. Constrained Damping Layer (High Temperature Resistant Reinforcement Patch) has broad prospects and applications in automotive, subway, ship and aerospace industries.
