| Abstract: | Carbonyl iron powder was added into the sizing agent of non-circular SiC fibers.Permeability of the systems was changed,and the property of microwave-absorbing was improved.The bandwidth corresponding to the reflection loss below -5 dB of trilobal SiC fibers/carbonyl iron powder increases by 1.6 GHz compared with single fibers,while the bandwidth of reflection loss below -10 dB increases by 2.48 GHz.And the bandwidth corresponding to the reflection loss below -5 dB of swirl-shaped SiC fibers/carbonyl iron p... |
