Piezoelectric ceramic-epoxy lattice structures: a hybrid manufacturing approach for enhanced electro-mechanical performance
Source abstract
Abstract
Piezoelectric composites are widely studied for applications in electronics, automotive, and aerospace systems. This work introduces a novel strategy to enhance performance by reinforcing Barium Titanate (BTO)-epoxy composites with 3D-printed zirconia triply periodic minimal surfaces (TPMS) scaffolds. Using digital light processing (DLP) and resin infiltration, Gyroid and Primitive Piezoelectric Ceramic-Epoxy Lattices (P-CELs) were fabricated and compared with a bulk control. The Primitive P-CEL exhibited the most favorable response, with an elastic modulus ~20% higher than the Gyroid and ~5% higher than the bulk control. Its normalized piezoelectric coefficients were markedly improved, with d33 enhanced by ~2570% and g33 enhanced by ~120% relative to the bulk control. Cyclic loading of the Primitive P-CEL produced specific voltages ~575% greater than the control and ~60% higher than the Gyroid P-CEL. These results demonstrate that hybrid TPMS architecture effectively couples mechanical integrity with amplified electromechanical response, establishing a pathway towards next-generation high-performance piezoelectric devices.
