Research Status on Polymer Damping Composites

Characteristics of polymer damping composites were presented. The damping mechamism of polymer were introduced also in detail from the respects of intrinsic viscoelasticity of pure polymer, phase interface, damage zone, viscoplasticity and thermoelastic, as well as the preparation method of the physical blending and chemical modification for damping composites. In particular, the effect of microstructure on damping property of composites was discussed highlighted. At last the major research directions of polymer damping materials were pointed out.
