This paper presents fabrication of an aluminum-based piezoelectric composite using hollow piezoelectric ceramic fiber. As the piezoelectric ceramic fiber is very fragile, the interphase forming/bonding (IF/B) method proposed by Asanuma was applied for embedding it in an aluminum matrix without losing its functions, and also forming an internal electrode inside the hollow fiber by filling the Al-Cu alloy produced during the IF/B process. In order to clarify the forming process of the internal electrode, the effects of hot-pressing condition and process on forming rate of the electrode were investigated. According to the results, most of the electrode is found to be composed of the Al-Cu alloy produced during the holding of the hot-pressing at 873 K. The filling rate in the hollow with the produced Al-Cu alloy attained to almost 100 % at around the hot-pressing period of 3.0 ks.
