ABSTRACT
With the development of piezoelectric ceramic fiber manufacturing technology, 3-D braided technology was applied to the fabrication of piezoelectric ceramic fiber composite. Ruan et al. (1999) studied the effective elastic constants, piezoelectric constants and dielectric constants of the 3-D twostep braided piezoelectric ceramic fiber composite by using 3-D connectivity model and an averaging technique. Based on an incompatible displacement finite-element method and the homogenization method, Feng & Wu (2001) examined the effective properties of 3-D four-step braided piezo-ceramic fiber composite.
