Abstract
SiC coating for carbon/carbon composites was prepared by pack cementation method. The effects of coating process on the microstructure and the mechanical properties of C/C composites were analyzed by SEM and three-point bending test, respectively. As the infiltrated Si improved the interfaces bonding during the coating process, the flexural strength and flexural modulus of SiC-coated carbon/carbon composites were both increased by about 10% than the naked C/C composites. In addition, the mechanism of the change of failure mode of SiC coated C/C composites and naked C/C composites was addressed.
