Effect of Polymer-Ceramic Fibre Interphase Design on Coupling Factor in Low Fibre Volume Content Piezoelectric Composites

Figure 1

An illustration of the 1-1-1-3 hybrid showing the single fibre component on the left with the PZT fibre, a soft polymer interlayer to reduce the clamping effect, and an epoxide shell to control the fibre content in the transducer. On the left side, the PZT fibres embedded in an epoxy matrix and an electrode hybrid disc is shown.
