- Abstract
The reception parameters Q[sup *, sub 33] and Q[sup *, sub h] of modified fiber composites based on high-e[sup FC, sub 33]/C[sup FC, E, sub 33] ferroelectric piezoceramics (e[sup FC, sub 33] is the piezoelectric constant, c[sup FC,E, sub 33] is the elastic modulus) are considered as functions of the electromechanical properties and the porosity of the components. Pore configurations at which the values (Q[sup *, sub 33]² ≈ (Q[sup *, sub h])² ≈ 7 × 10[sup -9] Pa [sup -1] for the polymer matrices of 1-0-3 composites are much higher than for conventional ternary composites are analyzed.
