This paper describes fabrication of a piezoelectric ceramic fiber/aluminum alloy composite using the Interphase Forming/Bonding(IF/B) method. A metal-core piezoelectric ceramic fiber is very fragile and reactive with molten aluminum, therefore general fabrication processes such as diffusion bonding and casting are hard to be applied. In this study, hot pressing condition was examined in order to embed the metal-core piezoelectric ceramic fiber without mechanical damage and loosing piezoelectricity to an aluminum alloy matrix instead of the pure aluminum matrix used in the previous studies. As the results, the proper hot pressing conditions such as temperature, pressure and period have been determined, and the piezoelectricity of the embedded fiber was confirmed by the measurement of P-E hysteresis loop. The proper hot pressing condition, that is, pressure and temperature are 2.2 MPa and 873 K, respectively enables to remove the coarse and fragile eutectic alloy phase from the composite.
