Laminated structures in Terfenol-D/Epoxy particulate composite were obtained via dynamic orientation by oscillating magnetic field. The mechanism of this process was studied and was explained by magnetorheology. The influence of related factors on laminated structures was investigated, including oscillating frequency, magnetic field intensity, particle size, and viscosity of epoxy matrix. A numerical simulation was conducted to model the evolutional process of laminated structures formation, and results consistent with our experiments were obtained. The dynamically oriented composites demonstrated an increase of magnetostriction by up to 300 ppm compared with statically oriented composites.
