摘要

In a high volume fraction particle-loaded piezocomposite, somenferroelectric particles appear to be in contact, as in a 3-3nconnectivity material; others are isolated in the polymer matrix, as inna pure 0-3 connectivity material. Such a material can be considered as ancomposite of composites characterized by a 3-3(0-3) connectivity. Thisnpaper follows two others that have described a matrix method toncalculate all of the effective parameters of pure 0-3 and 3-3nconnectivity piezocomposites. These previous models are used to obtainnthe effective properties of a 3-3(0-3) composite. A proportion of 0-3nconnectivity in the composite is introduced, and the effectivenproperties are studied as a function of this proportion. Experimentalnresults compared with these predictions show that the model allows annevaluation of the proportion of 0-3 connectivity through the analysis ofnthe electromechanical performance of the composite samples
