Outline of Final Research Achievements

The metal-core piezoelectric fiber/aluminum composite is a unique piezoelectric composite that exhibits piezoelectricity even under the high compressive residual stress that occurs during embedding, however it is unknown about the stress state and the piezoelectric and mechanical characteristics under this stress. In this study, we conducted a survey to analyze the compressive stress field and evaluate the effect of improving the mechanical properties due to the stress, and obtained the following findings. 1) The compressive residual stress generated in the piezoelectric fiber by FEM analysis was about 1 GPa at the interface of the fiber, which was in agreement with the experimental results. From this result, it became possible to predict the stress state occurring in the piezoelectric fiber. 2) Compressive stress is triaxial stress, which is predominant in the longitudinal direction. This residual stress improves the fracture stress of piezoelectric ceramics up to about 1.6 times.

Academic Significance and Societal Importance of the Research Achievements

圧電セラミックスは非常に脆弱であり,また圧縮応力を加えると特性が低下するという性質を持っている.金属コア圧電ファイバ/アルミニウム複合材料において極めて高い圧縮応力が3軸応力状態で圧電ファイバに作用するが,このような応力状態においても機能が発現することが確認されている.この応力状態における圧電セラミックス機能発現のメカニズム解明において,本研究で得られた特異な応力状態を予測できる手法は学術的に非常に価値が高い.また工学的にも,圧縮応力により圧電セラミックスの破壊応力が約1.6倍に向上したことは,圧電セラミックスの使用範囲が大幅に拡大するという,極めて価値の高いものであると言える.
