英文摘要 | The bamboo charcoal (BC)/SiC composite with a special honeycomb-like structure was prepared by an embedded sintering method with silicon powder and bamboo charcoal as raw materials. The morphology and phase composition of BC/SiC composite were investigated by scanning electron microscopy and X-ray diffraction. The dielectric properties of BC/SiC composite materials were investigated by a rectangular waveguide method. The results indicate that the main phases of BC/SiC composite material are β-SiC and amorphous carbon, and there is a small amount of α-SiC phase. The BC/SiC composite material has a honeycomb-like porous structure with three-dimensional aggregation structure layers, which have different diameter sizes and consist of interconnected SiC. The fracture toughness and bending strength of BC/SiC composite are 18.8 MPa·m1/2 and 34.5 MPa, respectively. The interface between the crystal structures of SiC/BC composite material improves the microwave absorbing absorption properties of SiC/BC composite. The maximum real part of dielectric constant of BC/SiC composite is 9.14, and the maximum imaginary part is 2.06. The lowest reflection coefficient is -10.16 dB at 10.7 GHz, and the effective absorption bandwidth is 2.1 GHz with the reflection coefficient of lower than -8 dB when the sample thickness is 2.5mm, showing the good absorbing absorpation performance of BC/SiC composites. © 2018, Editorial Department of Journal of the Chinese Ceramic Society.
