This paper describes comparison of output voltages generated from the metal core piezoelectric ceramic fibers embedded in various matrix materials, that is, aluminum, CFRP (Carbon Fiber Reinforced Plastic) and epoxy resin. The piezoelectric ceramic fiber/aluminum composite was fabricated by the interphase forming/bonding method, and the piezoelectric ceramic fiber/CFRP composite was fabricated by hot pressing. In the case of epoxy resin matrix specimen, the fiber was coated with silver paste to form outside electrode and embedded in the resin. Oscillation tests were carried out to compare aluminum matrix and CFRP matrix and impact tests were carried out to compare aluminum and epoxy matrix. As the results, it was found that the aluminum matrix composites have better response and lower voltages than the other two.
