摘　　要：Piezoelectric materials are capable of actuation and sensing and have been used in a wide variety of smart devices and structures.Active fiber composite and macro fiber composite are newly developed types of piezoelectric composites,and show superior properties to monolithic piezoelectric wafer due to their distinctive structures.Numerous work has focused on the performance prediction of the composites by evaluation of structural parameters and properties of the constituent materials with analytical and numerical methods.Various applications have been explored for the piezoelectric fiber composites,including vibration and noise control,health monitoring,morphing of structures and energy harvesting,in which the composites play key role and demonstrate the necessity for further development.压电材料同时具有驱动和传感性能,被广泛应用于各种智能结构中。圆形压电纤维复合材料和方形压电纤维复合材料作为两种新型压电复合材料,因其独特的结构而具有比压电陶瓷片更优异的性能。采用数值法和分析法对复合材料的结构参数及各组分材料性能进行评估从而预测复合材料的性能是目前的研究热点。压电纤维复合材料被广泛应用于振动及噪声控制、结构健康监测、结构变形及能量收集等领域,并能对上述领域的进一步发展发挥关键作用。
