光纤智能结构自诊断、自修复的研究

Research on self-diagnose and self-repair using hollow-center optical fiber in smart structure

监测与修复是光纤智能结构系统研究的难点之一。本文的系统中 ,包括研制空心光纤及其性能、复合材料损伤、断裂的监测以及利用注胶方法来进行复合材料的自修复等。本文简述了空心光纤的传光机理 ,对自诊断、自修复系统的总体方案做了具体的研究和分析 ,并通过实验论证了该方案的可行性。

Monitoring damage and repairing crack are the important problems in smart structures. A new system of self-diagnose and self-repair in smart structures is put forward, including the manufacture of hollow-center optical fiber ad its performance, inspection of damage and crack in composite material, and using hollow-center optical fiber filled adhesive to repair automatically. Based on this thought, the mechanism investigation and analysis of light transmission in hollow-center optical fiber are made in brief. The whole system of self-diagnose and self-repair is put forward in detail. The experiment is made to confirm the method finally.
