Abstract

The detection of delamination damage is important in ensuring the safety of composite structures. In this paper, a novel approach for delamination detection is described. The new approach involves (1) the application of a moving load on the composite member, and (2) measurement of total extension in embedded optical fiber(s). A theoretical study indicates that with the new approach, a single loading test can provide sufficient information to deduce the delamination location (in both the length and thickness directions) as well as the delamination size. Multiple delaminations can also be easily detected if there is no significant interaction between them. While further analysis and experimental work are necessary, the feasibility and potential of the proposed delamination detection technique has been established.
