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