PAN L J, ZHANG B M, DAI F H. Loss factor of viscoelastic dampingcomposite material under harmonic excitation [J]. Journal of Vibration and Shock, 2008, 27(2): 57-60.
Therefore, by determining the intensity of ultrasonic damping, the mechanical properties of composite can be predicted directly.
结果表明,可以通过超声衰减的?度直接预测复合材料的力学性能。

Dynamic mechanical thermal analysis showed that the addition of TPR improved the damping of the composite, but decreased the storage modulus and the glass transition temperature of the composite.
