摘　　要：以树脂为基体,制备了非晶Fe-Si-B质量分数为20%-80%的环氧树脂基复合材料和酚醛树脂基复合材料.利用XRD、SEM 对所制备的材料进行物相组成和微观形貌分析,利用阻抗分析仪对其电学性能进行测试分析.测试分析结果表明,随着导电相含量的增加,复合材料介电常数、电导率均增加,且电导率和频率之间呈较好的指数关系.电抗在整个测试频段内均为负值,且随频率增加而减小,复合材料为电容性.In this paper,resin was used as matrix to prepare epoxy resin matrix composite and phenolic resin matrix composite,in which the content of amorphous Fe-Si-B powder vary 20wt% to 80wt%.The phase char-acterization,microstructure and dielectric properties of the composite were analyzed by XRD,SEM and imped-ance analyzer.The result suggested that both the dielectric constant and conductivity of the samples raised with the increase of the conductive phase,moreover,the conductivity showed a exponential relationship with fre-quency.The reactance decreased with the increase of frequency,and took a negative value over the testing fre-quency range which indicated a capacitive character.
