| 摘 要： | 研究了聚氨酯阻尼材料的动态力学性能。实验结果表明,交联密度是影响聚氨酯阻尼材料损耗因子(tgδ)的重要因素,增加分子链中侧甲基(—CH_3)数目,有利于提高材料的损耗因子值,拓宽阻尼温域;加入片状填料可增大材料内部的剪切运动,使内耗值增大。

| Abstract: | The dynamic mechanical property of polyurethane damping material has been studied. The experiment results show: The crosslink density is an important factor to influence the loss factor of polyurethane damping materials ,?Increasing the number of lateral methyl of backbone contributes to raise the value of loss factor and broaden the damping temperature range; Adding the planar filler can increase the shearing motion and the internal dissipation in materials. |
