Study on Wave-absorbing Properties of Layer-by-layer Distributed Composite Thermal Insulation Materials with Different Contents of SmFeN/YSZ

  • 摘要: 雷达检测技术的快速发展对发动机等热部件的吸波性能提出了更高的要求。常用的隔热材料钇锆氧(YSZ)没有吸波性能,目前采用在其中添加吸波剂的方式实现对雷达隐身。基于此,本研究通过增材制造技术,将不同质量比的吸波剂钐铁氮(SmFeN)和基体材料YSZ进行层状叠加,制备了具有垂直于入射电磁波的相界面的吸波体,构建出SmFeN/YSZ复合材料界面模型。研究结果表明,将YSZ粉末与SmFeN金属颗粒按照不同质量比分层堆叠后,形成的SmFeN/YSZ异质界面提高了材料的微波吸收性能。当YSZ与SmFeN质量比为1∶1时,其反射损耗值达到最小,为-54.498 dB,有效吸收频宽达到最大,为2.5 GHz。
