摘要
近年来 ,用复合材料贴片修补有缺陷 ,含裂纹或被腐蚀的金属结构件已成为十分引人注目的研究和发展课题。复合材料修补比传统的机械焊接 ,螺接或铆接具有多种的优越性 ,其中包括改善疲劳性能 ,恢复刚度和强度 ,均匀修补局部的应力分布 ,密封联接 ,减轻重量和增强抗腐蚀能力等方面。本文综述了损伤金属结构件复合材料贴片修补研究和发展方面的最新进展 ,主要包括材料及其技术发展 ,分析模型的有关研究 。
The use of composite patches in the repair of defective/cracked or corroded metallic structures has seen rapid expansion recently. Composite repairs offer various advantages over mechanical fastening or riveting, including improved fatigue behavior, restored stiffness and strength, even distribution of stress over the entire bonded area, sealing protection of joined assemblies, reduced weight and improved corrosion resistance. The purpose of this article is to summarize recent efforts into the research and development of composite repairs bonded to defective structures. This review focuses on analytical models, materials and technologies and experimental data or experiences related to adhesive bonded composite repair in cracked metallic structures.
