| Summary | A description of the way to process 0-3 piezo-composite materials is presented. In particular, it is about the utilisation of a separation technique, taking advantage of the centrifugal force. The aim is to increase the amount of piezoelectric ceramic powder of the mixture with centrifugation. This process leads to a non-homogeneous two-ply material. The top of the sample is made of a clear resin ply and the bottom of a more compact layer. Another purpose of this work, is to show the good agreement of experimental results with those existing in literature, in terms of dielectric properties of the composite. A comparison between polyester and epoxy based piezo-composites is performed. This material could be helpful for the creation of an in-situ actuator, for the shape control of resin based composite structures. |
