Structural Health Monitoring of Composite Structures with Embedded Fiber Bragg Gratings
The use of composite materials has expanded significantly across civil, aerospace, and marine structures in both new designs and retrofits, and structural health monitoring (SHM) plays a key role for in-situ assessment.Fiber Bragg gratings (FBGs) are one attractive sensing solution due to a number of advantages such as embeddability.In this work, the embedding process and methodologies will be discussed and full spectral interrogation of the Bragg spectra are observed before and after the cure process to assess the effect of residual post-cure strain fields on the Bragg spectra.A series of wetting, static and dynamic load tests onfiber reinforced polymer specimens are performed for FBG performance validation, and a bolted connection failure scenario is conducted for SHM algorithm validation.
