Compared with other piezoelectric materials, 1-3 piezoelectric single crystal composite materials have excellent piezoelectric properties and better acoustic matching properties, which are better for preparing high-performance ultrasonic transducers. In this paper, the vibration mode and impedance characteristics of the composites were systematically investigated by the finite element software COMSOL, and the high-frequency Pb(In1/2Nb1/2)O3-Pb(Mg1/3Nb2/3)O3-PbTiO3(PIN-PMN-PT) ferroelectric single crystal/epoxy resin 1-3 composites were prepared by picosecond laser and their performance was characterized. The electromechanical coupling coefficient of the prepared 1-3 piezoelectric composites is 0.65, acoustic impedance is 19.96 MRayls. A high-frequency ultrasound transducer is fabricated by using the 1-3 composites. The transducer has center frequency of 17.68 MHz, -6 dB bandwidth of 84.38% and insertion loss of -25.4 dB.
