Abstract
In this study, the composites containing carbon black(CB) or carbon fibers were prepared, and the microwave absorbing properties and the absorption mechanism of them were investigated and discussed in the frequency range of 2－18 GHz, respectively. The optimum mass fraction of CB has been found as 6%, and the carbon fibers were discovered to absorb radar wave either under parallel or vertical polarization, the suitable gap distance between each bundle of which was 5 mm. According to the results of the single constitute absorber samples, the structured composites with the two kinds of absorbers combination were fabricated and studied at 2－18 GHz. The top layer absorbers affect the absorption performance a lot; the maximum reflection loss of composites with CB as top layer absorbers was －31.8 dB with the frequency range of 2.4 GHz below .10 dB, and the other type with CFs as the top layer absorbers obtained the reflection loss peak value of －31.4 dB with 2 GHz below-10 dB.

Keywords: radar absorbing structure; composites; carbon black; carbon fiber.
