Abstract

Optical fiber sensors are promising as tools for damage and structural health monitoring (SHM) of aerospace composite structures. Hence many researchers have conceived various kinds of optical fiber sensors. The authors and Hitachi Cable, Ltd. have developed small-diameter optical fiber and its fiber Bragg grating (FBG) sensor for embedment inside a lamina of composite laminates without strength reduction. First, the authors' studies on the small-diameter FBG sensors for damage monitoring and SHM of composite structures are described. Then, some recent results in the current ACS-SIDE (Structural Integrity Diagnosis and Evaluation of Advanced Composite Structures) project are presented on optical fiber based SHM for some feasible applications in aerospace composite structures.
