摘要:
以水泥为基体,添加硅灰和粉煤灰、石墨和碳纤维、纳米TiO2和钢纤维为吸波剂的试样,对8~18GHz频段内的隐身性能进行了试验分析,结果表明,硅灰和粉煤灰、纳米TiO2和钢纤维与水泥复合制成的吸波材料具有良好的隐身性能,石墨和碳纤维与水泥复合制成的吸波材料的隐身性较差,掺合材对水泥基材料吸波性能的影响必须综合考虑,并不是越多越好,掺合材超过一定极限后,材料的透波能力增强,吸波性能便会下降.在设计时对试件实验数据进行计算机模拟仿真,得到水泥基复合吸波材料,材料的电导率、复介电常数、复磁导率、介质损耗角正切等是评价吸波材料的主要参数.当掺合材作为复合吸波剂应用时,两种材料的介电损耗共同发挥衰减作用,可以明显提高试件的吸波性能,而且可以拓宽频段,比单一吸波剂的添加有着明显的优势
Abstract:
The absorbing performance has been tested and analyzed by taking cement as matrix, blending material silica fume and culver zed fuel ash, graphite and carbon fibers, nano-TiO2and steel fibers for absorbing agent trial Sample, in the 8~18GHz frequency band, the results indicate that silica fume and culver zed fly ash, nano-TiO2 and steel fiber and composite cement which is made of absorbing material have good stealth performance. Graphite and carbon fiber and cement composite made effective absorbing materials. Blending material to absorb properties of cement-based materials, the impact must be considered together. When blending material exceeds a certain threshold, enhance its ability of wave transparent enhance while stealth performance will be reduced finally. By using ANSYS software for computer simulation of the specimen to test experimental data, the issue to be cement-based composite absorbing material in design, the electrical conductivity, complex permittivity, complex permeability, dielectric loss tangent, etc of the material are all the main parameters of evaluate absorbing materials. When blending material is used as composite wave-absorbing agent applications, two kinds of material’s dielectric loss plays an attenuation role in common. It can significantly improve the absorbing properties of the specimen, and also broaden the band, which is more advantageous than adding a single wave-absorbing agent
