This paper describes the fabrication of the metal-core lead zirconate titanate (PZT) fiber/aluminum composite using the Interphase Forming/Bonding (IF/B) method in the air and its characterization. In the previous studies, in order to simplify the fabrication procedure and reduce their costs, the optical fiber/aluminum composites were fabricated using a compact hot-pressing equipment which enables rapid heating to reduce oxidation in the air as a model experiment. In this study, the metal-core PZT fiber/aluminum composite was fabricated in the air and piezoelectric property of the embedded fiber was confirmed by measuring its polarization-electric field (P-E) hysteresis loop. In addition, its characterization was investigated by an impact test. As the impact test, a steel ball was dropped on the composite and the output voltage from the composite was measured by an oscilloscope. The results obtained indicate that the output voltage is proportional to the square root of impact energy, and the output voltage depends on the impact directions.
