摘　　要：介绍了真空紫外线的模拟和射流式真空紫外辐射模拟设备的工作原理、技术参数及特点,并利 用该设备及其它分析手段对环氧树脂浇铸体(EP648)和碳/环氧复合材料(C/E648)在真空紫外线辐照作用下 的出气、质量损失率、层间剪切强度和表面状态的变化进行了研究。试验结果表明:真空紫外线辐照导致材料 产生明显的出气效应,质量损失率呈现先递增后趋于平缓的趋势;17280esh辐照剂量下,EP648的质量损失是 C/E648的3.4倍,C/E648的层间剪切强度与辐照前相比下降了13.3%;环氧树脂破损较重,而碳纤维表面状 态基本完好,并对内部的环氧树脂起到一定的保护作用。The simulation of vacuum ultraviolet (VUV) and the working mechanism, technical parameters as well as characters of the gas-jet device for simulating vacuum ultraviolet were introduced. The outgas, mass loss ratio (fSAML), interlayer shear strength (δILSS), and variation in surface state of epoxy cast ingot (EP648) and carbon/epoxy composites (C/E648) under VUV were studied using the above device as well as other analysis means. Results show that VUV exposure resulted in obvious outgas effect, while mass loss ratio shows a trend of ascending followed by leveling off; the mass loss of EP648 is 3.4 times of that of C/E648 under dose of 17280 esh; δILSS of C/E648 after exposure is decreased to 13.3% of that before the exposure; the epoxy is damaged greatly, while the surface of carbon fiber keeps in good condition serving as a protection for the insider epoxy.
