Verification of Robustness in Smart Composite Structures

Abstract:

In order to implement health monitoring methods in composite material structures that are being developed and manufactured, a series of preliminary tests was conducted. The aim was to check the influence of an implemented SMART® layer on a graphite-epoxy structure, its durability and its ability to detect changes in the structure. A series of preliminary tests was conducted, in order to check the mechanical and electrical properties of the plate-sensors system (strength, rigidity, PZT capacitance, response to voltage input). The outcome of these experiments showed that the SMART Layer® (by Acellent Technology Inc.) increased the graphite-epoxy plate's flexibility, and the piezo-sensors were found to survive this procedure with no distinguishable damage. Subsequently, experiments were performed, to detect changes in boundary conditions imposed on the plate. A visual verification indicating changes in boundary conditions or the presence of simulated damage was received.
