A REVIEW OF REPAIR TECHNIQUES FOR AVIATION COMPOSITE MATERIALS UNDER IMPACT DAMAGE

Abstract

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
