Structural health monitoring of composites for aircraft structures
This paper discusses about Acoustic emission technique where in the minute cracking noise sensed using both piezo-electric and fibre optic sensors. Fibre optic sensors could effectively be used as a sensor to measure Temperature, Strain, Pressure, etc. Surface bonded Piezo-electric and fibre optic sensors – Fibre Bragg Grating (FBG) are used to sense
Acoustic Emissions (AE), to gain insight into failure initiation and progression.
