摘　　要：通过对空心玻璃微珠(HGM)/环氧树脂复合材料进行动态力学分析(DMA),给出了环氧树脂基体在不同频率下的动态力学温度谱,利用时温等效原理,根据位移因子构建了HGM/环氧树脂复合材料在室温下的储能模量和损耗模量的频率主曲线。分析了温度和频率、体积比和粒径对HGM/环氧树脂复合材料储能模量和损耗模量的影响规律,并结合SEM图像分析其影响机制。结果表明,随着HGM体积分数的增加,HGM/环氧树脂复合材料储能模量和损耗模量呈增大趋势;储能模量随温度升高而降低,损耗模量随温度的增加先增大后减小,在玻璃化温度附近形成一个峰值,HGM低于10%的配比有利于提高其动态力学性能。颗粒的团聚及界面的黏合均对HGM/环氧树脂复合材料的动态力学性能产生较大影响。The dynamic mechanical analysis（DMA）for hollow for glass microsphere（HGM）/epoxy resin composite was conducted.The temperature-dependent mechanical properties were given for HGM/epoxy resin composite.The storage and loss moduli master curves for HGM/epoxy resin composite were presented through application of the time-temperature superposition on measurements at a series of temperatures.The influence of temperature,frequency,volume ratio and particle size on the storage and loss modalus was analyzed,and the influence mechanism was investigated by SEM for HGM/epoxy resin composite.It is found that the storage and loss moduli of the composite both increase as the HGM volume fraction is increased.The storage modulus decreases with the increasing temperature,the loss modulus initially increases significantly with temperature and then decreases,forming apeak near the glass transition temperature for HGM/epoxy resin composite.Ratio of less than 10%is good to improve its dynamic mechanical properties.The agglomeration of particles and the adhesion of the interface have great influence on the dynamic mechanical properties of HGM/epoxy resin composites.
