The application discloses a
surface wave absorbing and suppressing
composite material, which comprises, from outside to inside, a wave-
transparent skin layer 1, a suppressing functional layer 2, an absorbing functional layer 3, a structural layer 4 and a reflecting layer 5, and each layer is fixed by an
adhesive layer; the thickness of the
surface wave absorbing and suppressing
composite material is 15-40 mm; the thickness of the
adhesive layer is 0.5-1 mm; the
surface wave suppressing efficiency of the surface wave absorbing and suppressing
composite material in a target
wave band is greater than 15 dB / m; raw materials are widely available, the preparation method is simple, and
batch production can be easily realized. Meanwhile, the
prepared material is reliable in performance and stable in quality; the prepared surface wave absorbing and suppressing composite material has good performances of resisting
mildew, resisting neutral salt spray, resisting
ultraviolet aging, resisting high temperature, resisting low temperature and the like, and can be better applied to marine environment.
