In this study, changes in the properties of neat, carbon and glass fiber reinforced polycarbonate via high dose rate gamma irradiation were investigated. Irradiations were carried out at dose rate of 737 Gy/h. Specimens were irradiated up to four different doses which were 10, 25, 50, 75 kGy. Total irradiation doses, irradiation dose, type and content of the additives were parameters used in estimation of radiation stability of specimens. Tensile testing, dynamic mechanical analysis (DMA), thermogravimetric analysis (TGA), attenuated total reflectance-Fourier transfor m infrared spectroscopy (ATR-FTIR), spectrophotometric analysis (for yellowness index) and scanning electron microscopy (SEM) were techniques applied for characterization of specimens. According to the results, End point criteria, which is specified for polymers used in radiated areas, were not observed in specimens by 75 kGy irradiation. Carbon fiber addition yielded more linear dependence than glass fiber regarding tensile strength values with respect to fiber content. Glass fiber and carbon fiber filled polycarbonates could be safely used in radiated areas up to a time at which total absorbed dose reaches to 75 kGy.

在这项研究中，研究了高剂量率伽马射线辐照下纯，碳和玻璃纤维增​​强聚碳酸酯的性能变化。以737 Gy / h的剂量率进行照射。样品被辐照至四种不同的剂量，分别为10、25、50、75 kGy。总辐射剂量，辐射剂量，添加剂的类型和含量是用于估计样品的辐射稳定性的参数。拉伸技术，动态力学分析（DMA），热重分析（TGA），衰减全反射-傅立叶变换红外光谱（ATR-FTIR），分光光度分析（泛黄指数）和扫描电子显微镜（SEM）是用于表征的技术标本。根据结果​​，终点标准，75 kGy辐射未在标本中观察到指定用于辐射区域的聚合物的聚合物。就纤维含量而言，碳纤维添加物相对于玻璃纤维的抗张强度值具有更大的线性依赖性。玻璃纤维和碳纤维填充的聚碳酸酯可以安全地用于辐射区域，直至总吸收剂量达到75 kGy。
