Unexpected failure in structures such as airplanes, bridges, and dams can have catastrophic effects. Structural health monitoring (SHM) is a way to monitor the integrity of such structures so that any critical deformation can be detected and acted upon immediately. Compared to most current SHM systems, which are applied to a structure's exterior, this research aims to introduce a polymer optical fiber (POF) based system that is an integral part of the construction material. Due to their fiber-like structure, optical fibers are well suited to be incorporated in textile composites. 3D orthogonal woven (3DOW) preforms are an excellent host for optical fiber sensors because the yarns are arranged in straight paths. During composite fabrication, a POF can be woven directly alongside yarns in the 3DOW preform, creating a smart composite. This allows access to interior locations where other sensing methods may not be able to detect. The overarching objective of this research is to prove smart composites composed of POF sensors embedded in 3DOW composites can function as viable structural health monitoring systems. Testing of this system mimics accidental impacts that can occur during a structure's lifespan by exposing the smart composite specimens to multiple low energy impacts at a localized site. The composite sensor system efficacy is then evaluated by establishing a relationship between the sensor's location, composite damage, and the resulting POF signal. This is used to determine the best location for optical fiber sensors to be placed within the composite so that they can accurately predict structural damage before failure occurs. More effort is needed to bring the optical fiber sensor technology to a fully mature readiness level. A market study also accompanies this work, which aims to identify technological trends and future end uses of the optical fiber sensors through a strategic text-based analysis method.
