摘　　要：研制一种2-2型圆管压电复合材料。将压电陶瓷圆管沿轴向方向均匀切割,把环氧树脂浇注于切槽,经打磨和蒸镀电极,制成2-2型压电复合材料圆管。对压电复合材料圆管的压电和介电性能进行测试,结果为谐振频率388 k Hz,带宽11.2 k Hz,声阻抗18.05 Pa·s/m3,相对介电常数859,声速3 200 m/s,d33常数480 p C/N,振动位移89.5 pm。该压电复合材料圆管适合做水平全向宽带换能器。A kind of 2-2 type piezoelectric composite circular tube was developed. By cutting circular piezoelectric ceramics along the axial direction, and putting the epoxy resin in the groove, the 2-2 type piezoelectric composite circular tube was formatted, and then was polished and evaporated electrode. The piezoelectric and dielectric properties of the material were tested. The results show as follows： the resonant frequency is 388 kHz, bandwidth is 11.2 kHz, acoustic impedance is 18.05 Pa·s/m^3, relative permittivity is 859, sound velocity is 3 200 m/s, d33 constant is 480 pC/N, vibration displacement is 89.5 pm. The piezoelectric composite circular tubes are suitable for horizontal omnidirectional broadband transducer.
