利用模压成型法制备了丁基橡胶压磁复合薄膜，并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：复合薄膜的阻抗随着粉体粒径和薄膜厚度的减小而增大；阻抗变化幅度随着粉体粒径的减小呈现出先增大后减小的趋势，随着薄膜厚度的减小而减小。用复合薄膜的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 from the Fe78Si9B13amorphous powders as reinforced material and butyl rubber as matrix by means of molding to shape, and influences of particle size and film thickness on the piezomagnetic property is also studied. The results showed that the impedance of composite film increases with the smaller particle size and the thinner film thickness. The results also showed that the rangeability of impedance increases first and then decreases with decreasing particle size and decreases with the thinner film thickness. The experimental results are theoretically analyzed with equivalent circuit model of piezomagnetic property of composite film and the conclusions are consistent with the experimental results.
