摘要
利用聚氨酯(PU)/环氧EP互穿网络聚合物,引入质量弹簧模型,利用质量块与鳞片纤维的协同作用制备了高阻尼、宽温域阻尼复合材料,考察表面修饰后的质量块在基体中的分散情况及其对阻尼复合材料动态力学性能的影响。利用扫描电镜(SEM)、动态力学热分析仪(DMA)对该阻尼复合材料的结构和阻尼性能进行了研究。结果表明,作为质量弹簧模型中的质量块的加入和其存在的形态对复合材料的阻尼性能有很大的影响,加入表面修饰后的质量块,阻尼复合材料损耗因子为0.4的阻尼温域达到80℃。
A kind of high damping, wide temperature range damping composite material was prepared by using polyurethane （PU）/EP epoxy interpenetrating polymer network with mass spring model, and synergistic reaction of mass and synergy of flake fiber.The quality of the piece after surface modification on the dispersion in the matrix and its effect on damping dynamic mechanical properties of composite materials was studied by using scanning electron microscopy （SEM）, dynamic mechanical thermal analyzer （DMA）. The damping structure and damping properties of the composites were studied. Results show that as the quality of the mass spring model, its existing form of the damping properties of the composite material has a great influence,damping composite.The damping temperature range reached 80℃ when lossing factor is 0.4.
