Complex Permittivity of 3D Textile SiC/C/SiC Composites Fabricated by Chemical Vapor Infiltration at X-band Frequency

摘要：

　　Three-dimensional textile SiC fiber reinforced SiC composites with pyrolytic carbon interfacial layer (3D-SiC/C/SiC) were fabricated by chemical vapor infiltration.The microstructure and complex permittivity of the 3D textile SiC/C/SiC composites were investigated.The flexural strength of the 3D textile SiC/C/SiC composites was 860 MPa at room temperature.The real part (ε) and imaginary part (ε) of the complex pemitttivity of the 3D-SiC/C/SiC composites are 9.11~10.03 and 4.11~4.49,respectively at the X-band frequency.The 3D-SiC/C/SiC composites would be a good candidate for structural microwave absorbing material.
