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.
