The invention relates to the technical field of wave-absorbing composite materials, and particularly discloses a honeycomb sandwich structure high-temperature-resistant broadband wave-absorbing composite material based on Ti3C2Tx MXene aerogel and a preparation method of the honeycomb sandwich structure high-temperature-resistant broadband wave-absorbing composite material based on the Ti3C2Tx MXene aerogel. The high-temperature-resistant resin-based composite material wave-transparent skin, the honeycomb structure wave-absorbing layer and the high-temperature-resistant resin-based composite material reflecting skin are sequentially arranged from outside to inside, and the honeycomb structure wave-absorbing layer is of a composite material honeycomb structure filled with a high-temperature-resistant MXene composite aerogel material. According to the honeycomb sandwich structure high-temperature-resistant broadband wave-absorbing composite material based on the Ti3C2Tx MXene aerogel, the MXene composite aerogel material (the density is 2 mg/cm < 3 >-15 mg/cm < 3 >) and the light composite material honeycomb structure carrier are used, the defect that an existing wave-absorbing material is large in density is overcome, the effective absorption frequency band width can reach 10 GHz or above when the reflectivity is lower than-10 dB, and the wave-absorbing composite material is suitable for being used as a wave-absorbing material. The requirements of aerospace craft equipment on broadband wave-absorbing performance and light weight of the wave-absorbing material can be met at the same time.

    本发明涉及吸波复合材料技术领域,具体公开了一种基于Ti3C2Tx MXene气凝胶的蜂窝夹芯结构耐高温宽频吸波复合材料及其制备方法,所述蜂窝夹芯结构耐高温宽频吸波复合材料为多层结构,从外至内依次包括耐高温树脂基复合材料透波蒙皮、蜂窝结构吸波层、耐高温树脂基复合材料反射蒙皮,所述蜂窝结构吸波层为耐高温MXene复合气凝胶材料填充的复合材料蜂窝结构。本发明的基于Ti3C2Tx MXene气凝胶的蜂窝夹芯结构耐高温宽频吸波复合材料,使用MXene复合气凝胶材料(密度为2mg/cm3~15 mg/cm3)和轻质复合材料蜂窝结构载体,克服了现有吸波材料密度大的缺陷,反射率低于‑10dB的有效吸收频带宽度可达10GHz以上,能够同时满足了航空航天飞行器装备对吸波材料的宽频吸波性能、轻量化需求。
