上海民航职业技术学院毕业论文飞机复合材料损伤检测与维修姓 名:      专 业:  飞机结构维修  班 级:    完成日期:     指导教师:      上海民航职业技术学院毕业设计(论文) I摘要复合材料是由两种或两种以上的原材料,通过各种工艺方法组合成的新材料。其应用在航空领域越来越广泛。对于现代飞机来说复合材料的应用对减重、耐腐蚀和降低成本有着重要的作用。对飞机结构轻质化、小型化和高性能化起着至关重要的作用。复合材料在飞机上的应用日趋广泛,其应用和修理水平亟待提高。论文介绍了飞机复合 材料的损伤特征和可用于飞机复合材料损伤无损检测的目视、敲击、阻抗、谐振、超声、射线照像、红外热图和声发射等检测法,并结合实际介绍了不同类型复合材 料结构和缺陷检测方法的选择。关键词:复合材料;损伤检测;维修 上海民航职业技术学院毕业设计(论文) IIABSTRACTComposite materials are composed of two or more than two kinds of raw materials. Its application in aviation field is more and more extensive. For modern aircraft, the application of composite materials has an important role in weight loss, corrosion resistance and cost reduction. It plays an important role in the light weight, small size and high performance of the aircraft structure. The application of composite materials in aircraft is becoming more and more extensive, and its application and repair level need to be improved. This paper introduces the damage characteristics of aircraft composite material and can be used for nondestructive detection of visual, percussion, impedance, resonance, ultrasound, X-ray, infrared thermography and acoustic emission detection method of damaged aircraft composite materials, and introduces different types of composite structure and defect detection method combined with the actual choice. Key words: composite material; damage detection; maintenance 上海民航职业技术学院毕业设计(论文) III目录第 1 章 前言 ..................................
