冲击损伤下航空复合材料修复技术研究进展

摘要/Abstract

摘要： 先进复合材料在航空领域的广泛应用,尤其是在主承力结构方面的应用,对复合材料维护和修理工作提出了新的、更加迫切的要求。复合材料结构具有各向异性和非均质性的特点,对分层损伤和层间断裂十分敏感,此类损伤会造成复合材料结构强度和性能的大幅降低,进而对航空飞行器的结构安全造成灾难性的后果。冲击载荷正是导致此类损伤的最大威胁,因此,对复合材料结构的冲击损伤规律及其修复技术的研究成为近年来的热点和难点。从冲击损伤评估、无损检测和修复技术三方面综述了当前国内外的主要研究进展,展望了冲击损伤下航空复合材料修复技术的发展前景。

Abstract: Advanced composite materials are widely applied in aviation industry, especially in primary aviation structural components, which brings new and urgent requirements for composite structural maintain and repair techniques with high efficiency and reliability. The anisotropy and heterogeneity make composite materials highly susceptible to delamination and inter-laminar fracture, and this form of damage can sharply reduce the strength and property of the structure, which can bring catastrophic consequences to aviation aircrafts. For this type of damage is mainly induced by impact load, impact damage model and repair techniques of composite materials have been the focus of hot research. This article reviewes the main research progress of domestic and foreign. Firstly, impact damage assessment was introduced. Then, several advanced technologies of non-destructive inspection were listed to indicate the trend of intelligent and precise development. Three main repair techniques were enumerated, including bolting or riveting connection repair, adhesive bonding repair and injection repair. Last but not least, the prospects of developing tendency of repair techniques were presented.

Key words: aviation composite materials, impact damage, composite repair techniques
