The Cf/SiC/Ni and Cf/MoSi2/SiC/Ni composites were prepared by a hydrothermal reaction-sintering method using glucose, Si powder, and carbon fiber as raw materials and nickel as a catalyst, respectively. The phase composition, microstructure and absorbing properties of Cf/SiC/Ni and Cf/MoSi2/SiC/Ni composites were characterized by X-ray diffraction, scanning electron microscopy and waveguide, respectively. The results show that SiC nanowires are grown sparsely and unevenly in the Cf/SiC/Ni composites. The minimum reflection loss at 8.20 GHz is -14.61 dB, and the effective absorption bandwidth is 0.23 GHz when the thickness of the grown SiC nanowires is 1.5 mm. The massive SiC nanowires are grown densely and uniformly on the surface of carbon fiber of Cf/MoSi2/SiC/Ni composites. The minimum reflection loss is -34.14 dB at 9.10 GHz, and the effective absorption bandwidth is 2.18 GHz when the thickness of the grown SiC nanowires is 2.0 mm. Compared to Cf/SiC/Ni composites, the wave absorbing properties of Cf/MoSi2/SiC/Ni composites are improved. It is indicated that MoSi2 is a key factor improving the structural and absorbing properties of Cf/SiC/Ni composites.
