| 摘 要： | 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。

| Abstract: | The magnetic composites were prepared by mixing bisphenols A WSR-615 and glycidyl amine AG-80 epoxy resins and a high content of Fe-Si magnetic particles using hot-pressing process. The glass transition temperature and impact property of the epoxy resins and the impact strength and magnetization of the composites were investigated as a function of Fe-Si content and temperature. It is shown that the impact strength and the magnetization of Fe-Si/epoxy composites increase with increasing the Fe-Si content and are enhanced from 4.03 kJ/m2 and 162.07 emu/g to 7.16 kJ/m2 and 175.04 emu/g at 54 vol% to 66 vol% Fe-Si particles. The impact strength and magnetization of the composites are very lightly sensitive to the temperature change from-60 ℃ to 140 ℃, which is desired for practical applications requiring that the mechanical and magnetic properties are stable as the temperature changes. |
