摘要
综述了聚氨酯阻尼材料近年来的研究进展,简要概括了聚氨酯阻尼材料的阻尼机理及评价标准,重点讨论了软硬段结构及填料等对阻尼性能的影响,最后展望了其发展趋势。
The research progress of vibration-damping materials based on polyurethane in recent years was re-viewed. The damping mechanism of polyurethane materials and evaluating criteria for their damping performance was introduced, and then the effects of the hard and soft segments of polyurethanes and fillings on damping proper-ties were discussed in detail. Finally, the developing trend of the polyurethane damping materials was pointed out.
