(CPT) ceramic/epoxy composites have been prepared by Burn Out Plastic Spheres(BURPS) method and vacuum impregnation of epoxy. The piezoelectric properties of CPT/epoxy composites have been investigated as a function of initial pore size and CPT volume fraction. The piezoelectric coefficient(d
33
), dielectric constant, piezoelectric voltage coefficient(g
33
), electromechanical coupling factor(K
t
) and thickness frequency coefficient(N
t
) increase with CPT volume fraction than initial pore size. |
