采用双酚A型WSR-615和缩水甘油胺型AG-80环氧树脂为基体,以Fe-Si磁性颗粒为填料,通过热压成型方法制备了高含量磁性Fe-Si颗粒/环氧树脂复合材料.研究了环氧树脂基体的玻璃化温度和冲击强度及Fe-Si磁性颗粒含量对Fe-Si/环氧树脂复合材料的冲击强度和磁化强度的影响及温度敏感性.研究结果表明:随着磁性颗粒含量的增加,Fe-Si/环氧树脂复合材料的冲击强度和磁性能增加.当磁性颗粒体积分数由54 vol％增加到66 vol％时,Fe-Si/环氧树脂的冲击强度和饱和磁化强度分别由4.03 kJ/m2和162.07 emu/g增加到7.16 kJ/m2和175.04 emu/g.Fe-Si/环氧复合材料在-60℃～140℃范围内的温度敏感性低,符合实际应用对复合材料稳定性的要求.
