Resistance of fiber reinforced resin matrix composites to gamma radiation aging
摘要
Abstract
Fiber-reinforced resin matrix composites(FRP)are widely used in the nuclear industry,and inves-tigating 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 res-ins 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 in-frared(FTIR)spectroscopy.These resins were then combined with glass fiber(GF),basalt fiber(BF),and car-bon 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 prac-tical guidance for simplified engineering assessments of radiation tolerance in structural materials.关键词
