A Brief Discussion on Structural Damage and Detection and Maintenance Methods of Aircraft Composite Materials

Abstract

With the development of aviation industry,the application of aircraft composite structures is more and more extensive.The composite structure has the characteristics of light weight and high strength,which plays an important role in improving the performance and economy of aircraft.However,composite structures are also vulnerable to damage,such as cracks,delamination,fatigue,impact,etc.In order to ensure the flight safety and prolong the life of aircraft structure,it is necessary to study and apply the damage detection and maintenance methods of aircraft composite structures.In this paper,the classification and causes of structural damage of aircraft composite materials are discussed,and the methods of damage detection and maintenance are discussed.
