通过双层设计使水泥基吸波材料尽可能与空间波阻抗相匹配,同时具有良好的电磁波损耗特性,实验测试了水泥基吸波材料的吸波与力学性能,并对吸波材料进行了微观分析.研究结果表明,水泥基吸波板在2~18 GHz频率范围内低于－10 dB的有效带宽分别为3．7和10．8 GHz,水泥基吸波材料的力学性能优于基准材料,掺入0．5％碳纳米管可有效提高水泥净浆的抗压强度.
By double designing,absorbing materials make it possible that match with space wave impedance, meanwhile,which has excellent electromagnetic loss characteristics.Testing the absorbing properties and me-chanical properties of cement-based materials and having macro analysis about absorbing materials are necessa-ry.Result shows that with double cement-based in 2-18 GHz frequency range below -10 dB,the effective bandwidth of absorbing panel is 3.7 GHz and 10.8 GHz.Mechanical properties of double cement-based absorb-ing materials are superior to the reference ones.And the mixing of 5% carbon nanotube will enhance the strength of resistance of cement paste effectively.
