Ferrite/carbon composite inorganic foam wave-absorbing material and preparation method thereof
The invention discloses a ferrite/carbon composite inorganic foam wave-absorbing material and a preparation method thereof. The preparation method comprises the following steps: preparing nickel-zincferrite wave-absorbing powder meeting requirements through a ceramic synthesis process, preparing resin slurry from the powder, dipping a proper polyurethane foam material into the slurry, taking outthe polyurethane foam material, removing redundant slurry, curing and drying, putting the material into an atmosphere protection pyrolyzing furnace, and pyrolyzing to form the ferrite/carbon compositeinorganic foam wave-absorbing material. The composite inorganic foam wave-absorbing material disclosed by the invention is low in surface density, has an efficient absorption characteristic in a P-Kuwaveband, has high power bearing performance, can be independently applied to broadband high-power occasions, and meets the RCS reduction requirement.
本发明公开了一种铁氧体/碳复合无机泡沫吸波材料及其制备方法，包括以下步骤：首先通过陶瓷合成工艺制备符合要求的镍锌铁氧体吸波粉体，其次将粉体制成树脂浆料，将合适的聚氨酯泡沫材料浸渍于浆料中，取出去除多余的浆料，将其固化烘干。最后将材料放入气氛保护热解炉中热解，形成铁氧体/碳复合无机泡沫吸波材料。本发明复合无机泡沫吸波材料面密度低，在P至Ku波段具有高效的吸收特性，且具有较高的功率承受性能，可单独应用于宽带高功率场合，满足RCS缩减要求。
