摘　　要：目前,复合材料不仅在飞机结构中得到了大量的应用,而且还应用到飞机受损结构的维修中。本文主要研究复合材料在飞机结构修理中的设计应用。基于有限元方法,在有限元分析软件ANSYS Workbench下,建立飞机复合材料铝合金板胶结修理三维有限元模型,利用复合材料专用模块ANSYS Composite Prep/Post,对复合材料修复的含损伤孔洞的铝合金板的强度、刚度进行数值分析,分析补片长度和厚度对飞机损伤结构修复效果的影响,进而设计出合理的复合材料补片尺寸,使其确保飞机结构安全性的前提下,同时保证了维修的经济性。Nowadays,composite materials are not only widely used in aircraft structures,but also in the maintenance of aircraft damaged structures. The application of damage hole repairing of aircraft with composite material is studied. Based on the finite element method(FEM),a 3 D finite element model of aircraft for aluminum alloy plate with composite material maintenance is established by FEM software ANSYS Workbench. The strength and stiffness of aluminum alloy plate are analyzed with the variety of patch length and thickness by ANSYS Composite Prep/Post module. Then a reasonable size of composite material patch is designed to ensure the safety and economy of the aircraft maintenance.
