Abstract:
Analytical decisions for effective constants of a transversal-isotropic fibrous piezoelectric material with inverse polarization of the one-type phases taking into account conductivity and maxwell-wagner relaxation are received. The numerical analysis of unique dependences of the real and imaginary parts of effective constants of the composite from a polymeric piezoelectric material PVF from a volume fraction of fibers and the frequency of electric field is carried out. New effects are revealed: significant increase in piezosensitivity, dielectric permeability, conductivity and longitudinal module of shear.
Keywords:
piezocomposite, electroelasticity, maxwell-wagner relaxation, effective properties.
