【摘要】 通过电沉积技术在碳纤维表面制备了四氧化三铁磁性涂层。测试结果表明:通过电沉积法制备的磁性涂层均匀致密;磁性纤维具有优异的吸波性能,理论计算结果显示,当匹配厚度大于1.7 mm时,其最大损耗均低于-20 dB。这种磁性纤维有望实现复合材料的结构增强和吸波功能一体化。更多还原

【Abstract】 Electrodeposition technique was employed to fabricate Fe3O4 coated carbon fibers.The results showed that the Fe3O4 films prepared by electrodeposition were uniform and compact.The theoretical calculation revealed that the as-prepared magnetic fibers had excellent microwave absorption properties.When the matching thicknesses were larger than 1.7 mm,the minimum reflection loss were lower than-20 dB.The magnetic fiber is a promising material which may realize the integration of structural strength and functionality of composites.更多还原
