The results for a feasibility study on the inclusion of aluminum particles within cement/PZT composites are presented. The influence of aluminum on output voltage and power is investigated, which has not been done for piezoelectric-cement composites before. In the experiments, the amount of PZT was held constant at 50% (by volume), while the aluminum content was varied, 0%, 5% and 10% volume. The samples were subjected to g-loads that ranged from 0.5–2.0 g’s and frequencies between 200 and 250 Hz, while a resistive load of 1 ohm was applied to determine output power. The output power from samples containing 5% and 10% aluminum, produced ∼3.5 and ∼5.8 times more output power than samples containing only PZT and cement. We have also demonstrated that aluminum/PZT/Cement composites can be fabricated using a mix and cold-compression method.
