This paper presents fabrication and characterization of a metal-core lead zirconate titanate fiber/aluminum composite. In order to embed the fragile fiber, the IF/B method was used. The effects of fabrication conditions such as hot-pressing condition on the composite microstructure were investigated, and the optimum condition to embed it in the matrix without fracture and chemical reaction was obtained. Then, the effect of the very high compressive thermal residual stress working on the piezofiber on the output voltage characteristic of the composite was investigated by an impact test. The result obtained in this study indicated that the output voltage linearly increases with increasing strain up to the level much higher than that of the fracture strain of the fiber itself. Sensing capability of the composite embedded with several fibers was also investigated by another impact test. The results showed that the embedded fibers have possibilities to be able to work as distributed sensors to identify impact positions, and so on.
