Abstract

The current paper discusses the preparation of novel Fe-coated carbon fiber (CF@Fe) composites using metal organic chemical vapor deposition (MOCVD) for use as microwave absorbing materials. SEM, EDS, and XRD studies show that the MOCVD method can produce a uniform coating of iron on the CFs. Compared with common CF, the CF@Fe composites have higher resistivity and magnetic loss, which gradually increase with increasing iron content. At an CF@Fe weight fraction of 8 %, the minimum reflection loss (RL) is −38 dB at 13.4 GHz and a corresponding thickness of 2.5 mm. An RL exceeding −10 dB is obtained in the frequency range of 8–15 GHz and a thickness of 1.5–3.0 mm. The results indicate that the prepared composite has excellent electromagnetic absorption properties with lightness.
