Paper Abstract

In recent years, influence of volume, size and shape of particulate, stiffness of the polymeric matrix and mechanical preload on the magetostrictive property of polymer-bonded Terfenol-D composites have been investigated by several papers, however, few studies on the effects of the blending soft magnetic particles. In this study, polymer-bonded Terfenol-D composites composed with 20% volume fraction of Terfenol-D particulate and different volume percentage of carbonyl iron particle (i.e. 0, 10%, 20%, 30% and 40%) are fabricated. The changes of magnetostriction and magnetic permeability with changing applied field are tested. The experimental results indicate that with increases of fraction of carbonyl iron particle, the permeability of the composites increases, but the magnetostrictive property declines. The change of permeability is explained based on two ideal models, while the change of magnetostriction is explained from the perspective of energy transforming and mechanical property of matrix.
