Abstract: With the comprehensive development of national defense equipment technology, the Mach number of hypersonic missiles continues to increase, and the missile radome must have outstanding mechanical properties, stable high frequency dielectric properties, high temperature resistance and ablation resistance to meet more stringent operating conditions. Compared with ceramic wave-passing materials, the strength and toughness of fiber reinforced ceramic based wave-passing materials have been significantly improved. Ceramic fiber is not only the key material to improve the strength of the radome, but also has a close relationship with the overall working temperature of the radome. This paper focuses on the research progress of wave-transmitting materials and fiber reinforced ceramic based wave-transmitting materials. The research status of common ceramic material substrates (oxide ceramics, nitride ceramics), oxide fibers reinforcement (including quartz fibers, alumina fibers, mullite fibers, aluminosilicate fibers), nitride fibers reinforcement (boron nitride fibers, silicon nitride fibers) and fiber reinforced ceramic based wave-transmitting materials were reviewed. In order to provide reference for the subsequent development of fiber reinforced ceramic based wave-transmitting materials.
