This paper describes fabrication of a piezoelectric ceramic fiber/aluminum alloy composites by using the Interphase Forming/onding(IF/B) method and their characteristics. A metal-core piezoelectric ceramic fiber is very fragile and reactive with molten aluminum, therefore general fabrication processes such as diflusion bonding and casting are hard to be applied. In this study, it succeeded in embedding the metal-core piezoelectric ceramic fiber without mechanical and chemical damages to an aluminum alloy matrix instead of the pure aluminum matrix used in the previous studies. And output voltage characteristic of the piezoelectric ceramic fiber/aluminum composite was evaluated by impact test. According to the results, it was found that the output voltage generated from the composite is proportional to the square root of impact energy.
