“…Moreover, the FBGs are suitable sensing elements for doing physical measurements where a kind of displacement is available. Examples of such applications found in the literature include the measurements of strain (Ling H. Y. et al, 2006), pressure (Peng B. J. et al, 2005), force , acceleration (Antunes P. et al, 2011), tilt rotation by an angle , temperature (Gu X. et al, 2006) humidity (Arregui F. J. et al, 2002), magnetic fields (Orr P. et al, 2010), cardiorespiratory function , gait function analysis (Rocha R. P. et al, 2011) and integration on wearable garments (Carmo J. P. et al, 2012b).…”

“…While the failure criteria are very well defined for traditional materials such as metals, the failure criteria are much more complicated for composite materials [1]. Hence real time structural health monitoring (SHM) is crucial for composite material structures In this aspect, there has been a recent interest in SHM of composites using fiber optics [2,3], acoustic emission [4,5], ultrasonic [6,7], x-ray radiography [6] and eddy current [8,9] methods. Fiber optic sensors suffer from the weakness of being highly invasive difficult to integrate during composites manufacturing process, and require expensive and complicated instrumentation.…”

Abstract-Time domain reflectometry (TDR) offers the advantage of distributed sensing using a single transmission line sensor. In the present study, a parallel plate type non-invasive TDR sensor for structural health monitoring (SHM) of composites has been designed, modeled and experimentally tested. Five layer unidirectional glass fiber/epoxy composite specimens are fabricated. Specimens included a damage initiator in form of a cut in the central ply. The TDR sensor detects sub-surface damage in the composite non-invasively as the effective dielectric constant of the composite decreases due to the presence of delamination cracks. Previous work done on dielectrostriction is used to model the TDR response to strain changes. Qualitative agreement between theory and experimental results for strain sensing are found.
