With the rapid development of detection technology and the demand for operational performance,higher requirements have been put forward for radar stealth technology,honeycomb sandwich structure as a classical structural wave-absorbing material has made great development in recent years,this paper aims to com-prehensively analyse and summarize the characteristics,research status and application of honeycomb sandwich structure composites in the field of wave-absorbing stealth technology at home and abroad.This paper focuses on the key factors affecting the wave-absorbing performance of honeycomb sandwich structures,including the per-formance of absorbers,the design of honeycomb structures and the wave-transparent performance of skins,etc.It also analyses the advantages and disadvantages of different honeycomb sandwich structure wave-absorbing materials with respect to the key indexes of wave-absorbing bandwidth and absorption rate.In addition,this paper summarises the current development trend of honeycomb sandwich structure wave-absorbing stealth composites,summarises the current status of development,and gives an outlook on the future development direction.
