摘要/Abstract

摘要： 纤维增强树脂基复合材料在核工业中有着广泛的应用,对其耐γ射线辐射性能的影响因素和性能评估研究可为耐辐射材料改性与开发提供参考。本工作以四种树脂和三种纤维为研究对象,首先通过辐照前后的拉伸强度测试筛选出表现最好的双酚A型环氧树脂(Diglycidyl Ether of Bisphenol A,DGEBA)和不饱和聚氨酯树脂(Unsaturated Polyurethane resin,UPU)两种树脂,并结合傅里叶变换红外光谱分析对其耐辐射机理进行了解释;然后将两种树脂分别与玻璃纤维(Glass Fiber,GF)、玄武岩纤维(Basalt Fiber,BF)、碳纤维(Carbon Fiber,CF)复合,制备复合材料,并进行了辐照前后的拉伸、弯曲、压缩、短梁剪切强度测试。结果表明:DGEBA与BF和CF的匹配程度较好,UPU与GF的匹配程度较好,复合材料的耐辐射性能需要通过多种机械性能测试进行综合评价。本工作为耐γ射线辐射纤维增强树脂基复合材料的设计提供了研究基础,为工程材料耐γ射线辐射能力的简易评价提供了有益参考。

Abstract: Fiber-reinforced resin matrix composites (FRP)are widely used in the nuclear industry, and investigating the factors influencing their gamma radiation resistance and performance evaluation methods can provide critical insights for the modification and development of radiation-resistant materials. In this study, four types of resins and three types of fibers were systematically evaluated. Initial screening via tensile strength tests before and after irradiation identified diglycidyl ether of bisphenol A (DGEBA) and unsaturated polyurethane resin (UPU) as the top-performing matrices. The underlying radiation resistance mechanisms were elucidated using Fourier transform infrared (FTIR) spectroscopy. These resins were then combined with glass fiber (GF), basalt fiber (BF), and carbon fiber (CF) to fabricate composites, which were subjected to tensile, flexural, compressive and short-beam shear strength tests before and after irradiation. The results revealed that DGEBA exhibited superior compatibility with BF and CF, while UPU showed optimal interfacial synergy with GF. Furthermore, the radiation resistance of composites required a comprehensive evaluation of multiple mechanical properties rather than relying on a single metric. This work establishes a foundational framework for designing gamma radiation-resistant FRP and offers practical guidance for simplified engineering assessments of radiation tolerance in structural materials.
