Wave-absorbing ceramic composite material with continuous multilayer structure and preparation method of wave-absorbing ceramic composite material
The invention discloses a wave-absorbing ceramic composite material with a continuous multilayer structure and a preparation method thereof, the wave-absorbing ceramic composite material adopts ZrB2 nanoparticles and (ZrO2-SiO2) fiber reinforced SiOC ceramic, and the material is composed of a plurality of periodic unit layers. Each periodic unit layer comprises a ZrB2/ZrO2-SiOC layer and a SiO2-SiOC layer, and the ZrB2/ZrO2-SiOC layer and the SiO2-SiOC layer are arranged on the ZrO2 fibers in the ZrB2/ZrO2-SiOC layer are used as a skeleton, ZrB2 nanoparticles are dispersed in the ZrB2/ZrO2-SiOC layer as a wave-absorbing agent, and SiO2 fibers in the SiO2-SiOC layer are used as a skeleton. ZrB2 nanoparticles are also loaded in the matrix material of the upper layer, so that the upper layer has wave absorbing performance. The material is provided with the continuous impedance matching layer and the electromagnetic wave absorbing layer, so that the loss path of electromagnetic waves can be prolonged, and incident electromagnetic waves are attenuated layer by layer in the electromagnetic wave absorbing layers of the material and are fully absorbed.
本发明公开了一种连续多层结构的吸波陶瓷复合材料及其制备方法，该吸波陶瓷复合材料采用ZrB2纳米颗粒及(ZrO2‑SiO2)纤维增强SiOC陶瓷，该材料由多个周期单元层组成。每个周期单元层包含一层ZrB2/ZrO2‑SiOC层和一层SiO2‑SiOC层。ZrB2/ZrO2‑SiOC层的内部ZrO2纤维为骨架，ZrB2纳米颗粒最为吸波剂分散在该层中，SiO2‑SiOC层中SiO2纤维为骨架。上层的基体材料中还负载有ZrB2纳米颗粒，使得上层具有吸波性能。该材料具有连续的阻抗匹配层和电磁波吸收层，能够延长电磁波的损耗路径，使入射电磁波在材料的多个电磁波吸收层内被逐层衰减、充分吸收。
