Abstract

Recently, there has been growing demand in developing low-cost, effective structure health monitoring system for tidal turbine blades. Non-destructive structural health monitoring is essential for safety and reliability of marine kinetic energy related fields. In this work, with measuring the strain inside composites, we are developing a novel scheme to embed a resistive-strain-based thin-metal-film sensory into the blade sparcap that is made of composite laminates to determine structural integrity and presence of defects. The internal strain reading from embedded strain sensor under three-point-bending test standard is conducted. Experiment results shows that our proposed method will provide another SHM alternative to reduce sensing costs during the renewable green energy generation.
