研究了空心微珠表面改性和空心微珠体积分数对空心微珠/环氧复合泡沫塑料固体颗粒冲蚀磨损的影响。粉煤灰空心微珠被用作填料在接收和硅烷表面改性的配置。在室温下研究了不同冲击角度（30、45、60和90度）和速度（30、45和60 m/s）下的侵蚀行为。与复合泡沫相比，纯环氧树脂显示出最高的侵蚀速率。结果表明，复合泡沫塑料的冲蚀率与冲击角度和速度有很强的相关性。随着空心微珠含量的增加，所有冲击角度的侵蚀速率都降低。冲蚀率随冲击角的增大和速度的减小而减小。处理后的空心微珠具有良好的界面结合，提高了抗冲蚀性能。所有样品都表现出韧性侵蚀行为，在30度时侵蚀最大。速度指数和冲蚀效率参数证实了复合泡沫塑料的韧性行为。Polym.比较器：40：2109 - 2118，2019.

Influence of cenosphere surface modification and volume fraction on the solid particle erosion of cenosphere/epoxy syntactic foams is investigated. Fly ash cenospheres are used as filler in both as received and silane surface modified configurations. Erosion behavior is studied at room temperature for different impact angles (30, 45, 60, and 90 degrees) and velocities (30, 45, and 60 m/s). Neat epoxy shows the highest erosion rate compared with that of the syntactic foams. Results show a strong dependence of impact angle and velocity on erosion rate of syntactic foams. With increasing cenosphere content erosion rate decreases for all impact angles. Erosion rate decreases with increasing impact angle and with decreasing velocity. Good interfacial bonding of treated cenospheres enhances the erosion resistance. All the samples exhibit ductile erosive behavior, with maximum erosion at 30 degrees. The velocity exponent and erosion efficiency parameters confirm the ductile behavior of syntactic foams. POLYM. COMPOS., 40:2109-2118, 2019. (c) 2018 Society of Plastics Engineers
