The invention relates to the field of wave-absorbing materials, and discloses a porous carbon fiber wave-absorbing material, a preparation method thereof and application of the porous carbon fiber wave-absorbing material in a spacecraft shell. The porous carbon fiber wave-absorbing material is fibrous, nano-scale microporous structures are uniformly distributed in fibers, BET is 350-500m < 2 >/g, and 0.5-1.0 nm parts in the microporous structures at least account for 75%. The porous carbon fiber wave-absorbing material has a nano-scale microporous structure with specific BET and specific pore size distribution, is free of metal residues, not only has good wave-absorbing property and light weight, but also has good weaving property, is expected to break through the application method of coating a spacecraft shell with the porous carbon fiber wave-absorbing material as a coating in the prior art, and has wide application prospects. The material is directly woven to form the spacecraft shell with the wave-absorbing performance.
本发明涉及吸波材料领域,公开了一种多孔碳纤维吸波材料及其制备方法和在航天器外壳中的应用。该多孔碳纤维吸波材料呈纤维状,纤维中均匀分布有纳米级的微孔结构,BET为350‑500m2/g,且微孔结构中0.5‑1.0nm的部分至少占75%。本发明多孔碳纤维吸波材料具有特定BET和特定孔径分布的纳米级微孔结构以及无金属残留,该多孔碳纤维吸波材料不仅吸波性好、质轻,并且可编织性好,有望突破以往作为涂层涂覆在航天器外壳上的应用方法,直接利用该材料经编织后形成具备吸波性能的航天器外壳。
