Abstract
The influence of the aspect ratio and volume fraction of ferroelectric ceramic inclusions in a 0-3 matrix on the hydrostatic parameters of a three-component 1-3-type composite is studied to demonstrate the important role of the elastic properties of the two-component matrix on the composite performance. Differences in the elastic properties of the 0-3 matrix and single-crystal rods lead to a considerable dependence of the hydrostatic response of the composite on the anisotropy of the matrix elastic properties. The performance of a 1-0-3 0.92Pb(Zn1/3Nb2/3)O3-0.08PbTiO3 SC/modified PbTiO3 ceramic/polyurethane composite suggests that this composite system is of interest for hydroacoustic applications due to its high hydrostatic piezoelectric coefficients dh∗ ≈; (400-500); pC/N and gh∗ ∼ 0.1 V.mN, squared figure of merit dh∗gh∗ ≈ (30-40). 10-12Pa-1, and electromechanical coupling factor kh∗ ≈; 0.5-0.6.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
