真空电子辐照对碳纤维/ 氰酸酯复合材料的影响

利用空间带电粒子模拟设备模拟真空电子辐照环境,研究真空电子辐照条件下碳纤维/氰酸酯复合材料层间剪切强度和质量损失率变化规律,并利用XPS和SEM对辐照前后复合材料表面性质和断口形貌进行分析和表征。结果表明:150 keV真空电子辐照作用对碳纤维/氰酸酯复合材料表面影响较大,随着真空电子辐照注量增加复合材料质量损失率先快速增加后趋于平缓,而层间剪切强度先增加后略有降低。

Effect of Vacuum Electron Irradiation on Properties of CarbonFiber / Cyanate Ester Composites

The effect of vacuum electron irradiation on interlaminar shear strength and mass loss of carbon fiber/
cyanate ester composites was investigated by using space simulation equipment. XPS and SEM were used to characterize the composition and fracture micrograph of composites before and after electron irradiation. The results show thatvacuum electron irradiation of 150 keV has the influence on the surface of carbon fiber/ cyanate ester composites, andwith the increasing of irradiation fluence, the interlaminar shear strength of composites increases first, then decreases.The mass loss goes up quickly first, however, it tends to level off.
