Paper Abstract

Monitoring damage and repairing crack are the important problems in composite materials applications. In this paper, the method of self-diagnose and self-repair composite structures using hollow-center optical fiber filled adhesive is put forward. Based on this change, the measure method and experimental research of self-diagnose for the rupture location in composite structures are also put forward. To compare characters, experiments of composite with or without embedded optical fiber are performed. A general experimental system for self-diagnose and self-repair is given as an example. The key research issue is to diagnose the location of damage, to repair the crack and to compare the influence with or without embedded hollow-center optical fiber.
