摘　　要：复合材料作为一种新型材料,以其特有的优点已被广泛应用于航空、航天、建筑、桥梁等领域,复合材料的损伤修复已成为热点研究的项目。文中用现代光测技术,以飞行器上常用的复合材料作试件,用实时法测定了试件在不同激振力作用下的共振频率,再用时间平均全息干涉计量术拍摄了在特定共振频率下试件的原始状态、受损状态以及经光固化修复后的全息图。通过对拍摄全息图的比较和分析,结果表明,受损后试件的抗弯刚度减小;相对于试件的标准状态,光修复后试件振型基本恢复了原始状态,达到了较好的修复效果。实验验证了光修复技术应用的可行性,为光修复技术的应用提供了实验依据。As a typical new material,composite materials have been applied in the fields of aerospace,space,buildings,bridges and so on.Rapid repairing for damaged composites has become the hot topic of research projects.With common composite material for aircraft as test-piece,the real-time method was used to measure the resonant frequency under different excitation force by means of optic measurement technology.Holograms of original,damaged and the light-cured repaired test-piece were taken by using the average time holographic interference.After comparing and analyzing these holograms,a conclusion was drawn that bending rigidity of the damaged specimen decreased after damage.Optical vibration mode of the repaired test-piece basically has recovered to the original state,almost up to the standard conditions of specimens,which showed that composite materials had good repaired characteristics after mechanical damage.This experiment has proved the feasibility of optical repairing technology and provides an experimental basis for the application of light-repair in composite materials.
