Feasibility Study of Delamination Detection with Embedded Optical Fibers

In this paper, we describe a novel approach for delamination detection, which 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 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.
