| Abstract: | Through the detailed analysis of 0-3 piezo-composite Yamada model,discusses the influence to composite material piezoelectricity constant D33 by the performance of components in composite material system,find out the reason that the reckoned result of Yamada model is higher than the experimental result.Presents the methods to enchance the piezoelectric performance of the material: diminishing the difference of permittivity between components,coating material with transitional permittivity on ceramic particles,these measures are valuable for improving the piezoelectricity performance of composite material. |
