Carbon Fiber Reinforced

The reflectivity of ferrocene-doped carbon fiber-reinforced cement-matrix composites against the electromagnetic radiation was measured in the frequency range of 8-18 GHz for different carbon fiber contents of 0.4, 0.6, 0.89, 1.33, and 1.78 wt% by mass of cement. The ferrocene was doped in 0.89, 1.78, 3.56, 4.89, and 6.27 wt% by mass of cement respectively. The maximum reflectivity reached -4.0 dB when the fiber percentage was 0.89 and the ferrocene was 3.56. The microwave was attenuated by 64 % through reflection. The minimum reflectivity -7.5 dB occurred when the fiber percentage was 1.33 and the ferrocene percentage was 4.89. The microwave was attenuated by 67.5 % through absorption. Prior to the fiber percentage of 0.89 and the ferrocene percentage of 3.56, the reflectivity kept rising.
