Composite foams with 10–50 vol% hollow polymeric microspheres were prepared using bisphenol A epoxy resin and polyetheramine curing agent as the matrix. The results demonstrated that the density, hardness, and static mechanical properties of the epoxy resin/hollow polymer microsphere composite foams, as well as their dynamic mechanical properties under forced non-resonance, were similar to those of polymer/hollow glass microsphere composite foams. At 25°C and under 1–100 Hz forced resonance, the first-order and second-order resonance frequencies of the composite foams shifted to the low-frequency region as the volume fraction of hollow polymer microspheres increased. Meanwhile, the first-order and second-order loss factors of the as-prepared composite foams were improved by 41.7% and 103.3%, respectively, compared with the pure epoxy resin. Additionally, the first-order and second-order loss factors of the as-prepared composite foams reached a maximum at 40 vol% and 30 vol% hollow polymer microspheres, respectively. This research helps us to expand the application range of composite foam materials in damping research.

以双酚A环氧树脂和聚醚胺固化剂为基质，制备了具有10-50％（体积）中空聚合物微球的复合泡沫。结果表明，环氧树脂/中空聚合物微球复合泡沫的密度，硬度和静态力学性能以及在强迫非共振下的动态力学性能与聚合物/中空玻璃微球复合泡沫相似。在25°C和1–100 Hz的强制共振下，随着中空聚合物微球体积分数的增加，复合泡沫的一阶和二阶共振频率移至低频区域。同时，与纯环氧树脂相比，所制备的复合泡沫的一级和二级损失因子分别提高了41.7％和103.3％。另外，所制备的复合泡沫的一级和二级损失因子分别在中空聚合物微球体的40vol％和30vol％处达到最大值。这项研究有助于我们扩大复合泡沫材料在阻尼研究中的应用范围。
