铁氧体Ba(Zn_(0.65)Co_(0.35))_2Fe_(16)O_(27)/环氧树脂复合材料板吸波性能与优化

The absorbing properties and optimization of the Ba(Zn_(0.65)Co_(0.35))_2Fe_(16)O_(27) powders/M-glass fibers/epoxy composite panels

首先采用化学共沉和高温助熔工艺制备铁氧体Ba(Zn0.65Co0.35)2Fe16O27粉体,用手糊工艺制备铁氧体/M-玻璃纤维/环氧树脂复合材料板,再用波导法测定复合材料的电磁参数。研究表明当铁氧体Ba(Zn0.65Co0.35)2Fe16O27含量不变时,复合材料板的吸波性能随板厚度的增加而提升,且试样反射系数绝对值增加的幅度随试样厚度的增加而变少。将M-玻璃纤维/环氧树脂复合材料置于非晶粉体/M-玻璃纤维/环氧树脂复合材料前端组合成多层复合材料结构,可以改善复合材料板与空气的电磁匹配性能,提高复合材料板的吸波性能。

After the preparation of the ferrite Ba（Zn0.65Co0.35）2Fe16O27 powders by chemical co-precipitation and high temperature flux techniques,then we make up the ferrite powders/M-glass fibers/epoxy composite panels by manual technology.And then we use waveguide method to test the properties of the panels.The research shows that when the content of Ba（Zn0.65Co0.35）2Fe16O27 powders is constant,the absorbing properties of the composite panels increased with the adding of the thickness of the panels.The electromagnetic matching performance between the composite panels and the air may be improved when the M-glass fiber reinforced epoxy composite panels are set in front of the ferrite powders/M-glass fiber reinforced epoxy composite panels to form the multi-layer composite structure,and then can improve the absorbing properties of the composite panels.
