Abstract: SiBN(C) wave-transparent ceramic fiber, a key reinforcement for high temperature wave- transparent composites and radomes, is the structural and functional ceramic fiber with high temperature resistance, corrosion resistance, oxidation resistance and wave-transparent property. Combining with the advantages of Si3N4 fiber and BN fiber, continuous SiBN fiber is an ideal candidate as reinforcement in ceramic matrix composites for wave-transparent application. This paper reviewed the new progress of SiBN (C) wave-transparent ceramic fiber and predicted its future developments.
Key words: wave-transparent material; ceramic fiber; SiBN(C)
