Abstract
A multiscale simulation was carried out using a two-stage homogenization process to improve the performance of flexible, printable magnetoelectric (ME) polymer matrix composites. A periodically-poled checkerboard structure discovered in the multiscale optimum design of ceramic composites was applied to particle-dispersed polymer matrix composites, targeting a composite of piezomagnetic (PM) cobalt ferrite and piezoelectric (PE) barium titanate, and its effect was computationally verified. As a result, the periodically-poled reversal checkerboard structure improved the transverse ME constant by approximately 8.3 times compared to a conventional laminated structure. In addition, we investigated the effect of the matrix polymer Young's modulus (Em) on the ME constant as a new design variable. Due to the trade-off between strain transfer and PM and PE properties, the multiscale simulation showed that the maximum value of the transverse ME constant exists when Em is in the range of 1–2 GPa.
