| Research Abstract |
This study deals with the fundamental study of a novel optical fiber sensor monitoring system to realize the damage tolerance design of aerospace composite structures. First,"Visualization of damage initiation and growth and its theoretical formulation"is conducted for current advanced composites as a basic background research for the following health monitoring development. Then two different optical fiber sensor monitoring systems are developed to monitor the damage evolution in aerospace composite structures. One is"Monitoring system with Lamb wave detection"and the other is"Distributed strain monitoring system". Both optical fiber sensor monitoring systems are designed to characterize the damage evolution in composite structures in particular. Combination of two systems provides a more reliable and accurate characterization of the damage evolution in practical aerospace composite structures.
