A micromechanics method is developed to investigate the effects of porosity in the matrix and the polarization orientations of the piezopolymer matrix and the piezoceramic fibers on the performance of 1–3 piezoelectric composites. The Mori-Tanaka (MT) method is first used to homogenize the porous piezopolymer matrix, and then the MT method for piezoelectric composites is used to analyze the porous piezopolymer matrix with embedded piezoceramic fibers. Results show that the performance of the composites is significantly enhanced by the presence of pores in the matrix and further enhanced by the opposite polarization orientation of the matrix and the fibers.
