Research status and outlook of high temperature radar absorbing materials

Traditional radar adsorbing materials characterized by thin broad, light and strong can not fully satisfy requirements of advanced weapons with heat resistance, anti-oxidation, high strength and fracture toughness. Recently, high temperature radar absorbing materials have attracted much attention. Research progresses of three high temperature absorbers, including C, SiC and ZnO, were reviewed. Then ways to improve their microwave properties and mechanisms of their temperature respond behaviors were introduced. In addition, the coating and structural microwave absorbing materials were compared. On this basis, superiorities, research status and main problems of continuous fibers-reinforced ceramic matrix composites were elaborated. Based on these progresses, potential development directions of high temperature microwave absorbing materials were proposed.
