采用模压成型法制备Fe78Si9B13非晶粉体/丁基橡胶压磁复合薄膜,研究了粉体粒径和薄膜厚度对其压磁性能的影响规律。结果表明:复合薄膜的阻抗随粉体粒径和薄膜厚度的减小而增大;阻抗变化幅度随粉体粒径的减小呈现先增大后减小的趋势,随着薄膜厚度的减小而减小。用复合薄膜压磁性能的等效电路模型对实验结果进行了理论分析,所得结论与实验结果相符合。

Composite film was prepared with Fe78Si9B13 amorphous powders as reinforced material and butyl rubber as matrix by means of compression molding,and influences of particle size and film thickness on the piezomagnetic property were studyed. The results show that the impedance of composite film increases with the decrease of particle size and film thickness;the rangeability of impedance increases first and then decreases with particle size decreasing,and decreases with film thickness decreasing. The experimental results were theoretically analyzed with equivalent circuit model of piezomagnetic property of composite film,and the conclusions are consistent with the experimental results.
