Method & Evidence

AimTo evaluate the performance and impact of embedded piezoelectric fiber composite sensors (PFCS) on the structural integrity and health monitoring capabilities of composite materials.

MethodExperimental and Numerical Simulation

ProcedurePFCS were fabricated using micro-sized PZT fibers. Their performance characteristics (transfer function, sensitivity, nonlinearity, resolution, noise) were tested. Numerical simulations were used to analyze stress concentrations around the embedded sensors. Composite specimens (laminates and sandwich structures) with embedded PFCS underwent tensile, fatigue, flexural, and short beam strength tests. The voltage output of the PFCS was recorded during fatigue loading to correlate with stress amplitude changes.
