▎ 摘　　要

NOVELTY - Impact resistant structural absorbing material comprises first fiber-reinforced plastic (FRP) skin, surface layer of wave absorbing core material, FRP middle layer, bottom layer of wave absorbing core material and second FRP skin stacked from top to bottom. The polyurea absorbing coating is arranged on outside of first FRP skin of structural absorbing material. USE - The impact resistant structural absorbing material is used for improving Ka band absorbing performance (claimed). ADVANTAGE - The method realizes broadband strong absorbing function of L, s, C, x, Ku and Ka bands on the basis of having impact resistant function and electrical performance reaches first-class index of radar stealth specified in gjb1411a-2015 camouflage requirements for surface to surface missile weapon equipment system. DESCRIPTION OF DRAWING(S) - The drawing shows a structure schematic diagram of an impact-resistant structure wave-absorbing material for improving Ka frequency band wave-absorbing performance. First glass steel skin (1) Polyurea absorbing coating (2) Absorbing core material layer (3) Absorbing core material bottom layer (4) Glass steel middle layer (5) Second glass steel skin (6)
