Abstract
Carbon fiber (CF) was surface treated and then added to polypropylene (PP) to prepare composites. The magnetostrictive properties of the composites were investigated and the following phenomena were observed. Firstly, magnetostriction as large as 1163Â ppm was obtained in a magnetic field of 800Â kAÂ mâ1. Secondly, the magnetostriction is dependent on the magnetic field and time interval. With a constant magnetic field, the magnetostriction first increases linearly with time and then reaches a saturation level after an interval defined as the saturation time. On the other hand, for a given time interval the magnetostriction increases with magnetic field. Thirdly, with the magnetic field set to 0, the magnetostriction decreases continuously from the saturation value to zero over a considerable time. Finally, the magnetostrictive properties have a hysteresis effect, which is different from that of TbxDy1âxFe2ây, the typical inorganic magnetostrictive material.
