【 摘 要 】

The research aimed to find out the effect of the compound composition of magnetite (Fe3O4) and silica (SiO2) derived from natural materials silica are used as Fe3O4/SiO2 composite within the matrix of the Unsaturated Polyester Resin (UPR) as an electromagnetic wave-absorbing material. The research conducted by extracting magnetite from iron sand using co-precipitation method and silica extracted from rice husk ash calcination method. The experiment was conducted with compositing both of extraction product with a certain ratio in the matrix. The next sample is used as an electromagnetic wave absorbent composite material along with the UPR. Electromagnetic wave absorption tested on 8 GHz-12GHz frequency. The results prove that Fe3O4/SiO2/UPR material by the composition of the composite is 1:1 can absorb electromagnetic waves at a frequency of 10 GHz with an absorb range 14.5 dB.
