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 maximize the filling rate in the hollow with the alloy, the effect of hot-pressing condition was mainly investigated. According to the results, most of the formed inner electrode is composed of the Al-Cu alloy produced during the holding stage of the hot-pressing at 873 K. The filling rate attained to almost 100 % at around the hot-pressing period of 3.0 ks.
