Abstract

Fiber Bragg gratings may be utilized to monitor the structural integrity of key components of aerospace structures including composite parts, adhesive joints and deformation of surfaces. Key capabilities of this technology include the ability to measure multi-axis strain, strain gradients, and shear strain at multiple points along a single fiber line. This paper provides a brief overview of the utilization of this technology to provide diagnostics of the integrity of aerospace structures and monitoring the manufacturing of composite structures.
