Impressive Results in Vesoul and Caenlymer components . The .–. ferroelectric ceramic / polymer composites combine high piezoelectric activity of a ceramic with the beneficial mechanical properties of a polymer. A polymer is often chosen as the piezo-passive material and is characterised by low dielectric permittivity and low elas

https://doi.org/10.1007/978-1-349-17275-7t determining the effective properties of composites offers challenges and difficulties, even in the case of relatively simple two-component piezo-composites with well-defined microgeometry. These difficulties are closely connected with functions that would describe structural inhomogeneities and th

These procedures become complicated due to electromechanical coupling in the presence of piezo-active components. The role of the ferroelectric components has been considered in detail, demonstrati
