Active fiber composite and macro fiber composite are newly developed types of piezoelectric composites, and show superior prope此ies to monolithic piezoelectric wafer due to their distinctive structure咀. Numerous work has focused on the perforrnance prediction of the composites by evaluation of structural parameters and properties of the constituent materials with anal严ical and numerical methods. Various applications have been explored for the piezoelectric fiber composites, induding vibration and noise control, health monitori吨， morphing of structures and energy harvesting, in which the composites play key role and demonstrate the necessity for further development.
