摘要

玻璃纤维增强复合材料(GFRP)由于其重量轻、比强度高、耐腐蚀、电绝缘性能好等特性被广泛用于航天航空、管道运输等领域。由于其服役环境恶劣

容易遭受冲击形成局部材料损失缺陷

影响其结构完整性。对GFRP局部材料损失缺陷进行有效的无损检测十分重要。相比于其他GFRP无损检测方式

微波无损检测具有灵敏度高、非接触、无需耦合剂、快速等优势。围绕GFRP局部材料损失缺陷

集中探究基于微波反射测定法对该类型缺陷的无损定量检测可行性。实验结果证实了微波反射测定法对GFRP局部材料损失缺陷进行可视化定量检测的可行性。

Abstract

Glass fiber reinforced polymer（GFRP）material is widely used in aerospace

pipeline and other engineering fields because of its favorable characteristics including light weight

high strength

corrosion resistance and good electrical insulation

etc.Due to severe environments

it is prone to the localized material loss（LML）resulting from impact

which undermines the structural integrity of GFRP.Therefore

it is imperative to detect and evaluation LML in GFRP via effective nondestructive testing（NDT）methods.Compared with other NDT techniques

microwave NDT has the advantages in terms of high sensitivity

non-contact and efficient inspection without coupling agent

etc.Feasibility of microwave NDT of LML in GFRP in conjunction with microwave reflectometry is intensively investigated through experiments.The experimental results confirm the validity of microwave reflectometry for the visualization and quantitative evaluation of LML in GFRP.
