Abstract: A series and parallel unit cell model of 1-3 piezoelectric fiber comp osites (PFC) is presented, and the macro parameters including mechanical and el ectrical parameters of PFC are obtained via this model. Along the fiber direction, the parallel model is used to describe the mechanical and electrical capability of PFC, and in the transverse direction, the combined model is used to catch the mechanical and electrical capability of PFC. The numerical results verify th e feasibility of the combinaed model for PFC.
Keywords: 1-3 piezoelectric fiber composites(PFC), series and parallel model, mechanical parameters, electrical parameters.
