| ABSTRACT |
|
Generally the piezo-composites have superior hydrostatic response characteristics than PZT ceramics due to both the stress amplification effect in axial direction and stress reduction effects in radial direction. This paper described material properties of a 1-3 type piezo-composite that fabricated with ceramic injection molding (CIM) technology. The electro-mechanical performances of the composite have been analyzed using FEM and the physical properties of the composite have been measured with the vol% of the PZT ceramics. Based on the results, the $k_t$ increased rapidly as the vol% of the PZT ceramics increased up to 30 vol% and saturated the constant value in the above region. Also the experimental results have good agreement with the simulation values of the composite. Finally we developed the composites having high piezoelectric properties than the PZT ceramics with the CIM technology. |
