Explorative Research on the Magnetostriction of Carbon Black Filled Polypropylene Composites

Abstract:

Carbon black (CB) filled polypropylene composites were prepared, with CB modified by coupling agent. Three phenomena could be observed during the course of the magnetostrictive properties measurement. The first was that a relative large magnetostriction of 115ppm, comparative with that of metallic material, was obtained. The second was that the magnetostriction was strongly dependent on magnetic intensity and time interval. And the third was that obvious hysteresis effect appeared which was seldom found for material of Tb_xD_1-xFe_2-y thought as typical magnetostritive material.
