Mechanical and Electromagnetic Interference Shielding Behavior of C/SiC Composite Containing Ti3SiC2

In order to obtain the composites with the integration of structural and functional properties, Ti3SiC2 is introduced into C/SiC due to its excellent damage tolerance and electromagnetic interference (EMI) shielding properties. C/SiC–Ti3SiC2 has the lower tensile strength, while the higher compressive strength than C/SiC. The penetration energy of C/SiC–Ti3SiC2 in the impact experiment is improved at least three times than that of C/SiC, resulting from the improved damage tolerance. With the introduction of Ti3SiC2, the EMI shielding effectiveness increases from 31 to 41 dB in X‐band (8.2 to 12.8 GHz) due to the increase of electrical conductivity. C/SiC–Ti3SiC2 reveals the great potential as structural and functional materials based on the multi‐functional properties.
