3.1 Microgeometry of Piezo-Particulate Composites

The term ‘microgeometry ’ is often used along with the term ‘connectivity’ to characterise the specifics of the spatial distribution of components (or structural elements) in the composite sample. Interconnections between the composite microgeometry and specific connectivity pattern in the composite sample often facilitate a prediction of the effective properties for such connectivities as 1–3, 0–3, 3–3, etc. Figure 3.1 shows that knowledge of the connectivity and microgeometry is not sufficient to describe the composite architecture in detail. The next important term that makes this description easier is ‘microstructure ’. The term ‘microstructure’ is often used to describe the characterisation of the granular structure of FCs, air pores or channels and defects therein [9–13]. In the case of a composite, its microstructure is to be studied in the context of the microstructures of each component. The complex microstructure of many FCs can be an additional obstacle at the description of the composite and the prediction of its effective physical properties. Taking into account the ferroelectric nature of the main component of the composite, we should know specifics of the domain structure and its changes under external electric and/or mechanical fields.
