Abstract

Provided are a preparation method of a piezoelectric composite material, and the application thereof. The preparation method includes: step 1, designing a curved-surface 3D printed mesh mold and forming the curved-surface 3D printed mesh mold by printing; step 2, cutting a blocky piezoelectric phase into a plurality of small piezoelectric columns; step 3, inserting the small piezoelectric columns into empty cells of the 3D printed mold; step 4, filling gaps between the piezoelectric columns and the 3D printed mold with a non-piezoelectric phase such as an epoxy resin, and curing and forming the non-piezoelectric phase; and step 5, grinding, polishing, and ultrasonically cleaning a prepared sample, and then performing an electrode coating operation on the sample to obtain a curved-surface piezoelectric composite material.
