Abstract

This paper developed a smart sandwich structure with functional grading design on the re-entrant honeycomb core. Functional grading schemes of linear and bilinear cell ligament angle variation have been proposed. The sandwiches with the grading-designed cores were 3D printed, and piezoelectric P(VDF-TrFE) transducers were inserted between the sandwich facesheet panels and the cores. The smart sandwiches were tested in terms of their piezoelectric energy harvesting performance. It has been found that the sandwich with the optimised grading scheme could exhibit a maximum 158.7 nW power at its resonant frequency and under 0.71 g RMS sinusoidal excitation. The power generated by the sandwich with optimised core grading scheme was almost 60% higher than the sandwich with non-graded re-entrant honeycomb core.
