Influence of carbon preform density on the microstructure and ablation resistance of CLVD-C/C-ZrC-SiC composites

In chemical liquid vapor deposition (CLVD) technique, carbon preform density is a crucial factor to control the microstructure of C/C-ZrC-SiC composites, which also determines the ablation resistance. The effects of preform density on the microstructure and ablation behavior of CLVD-C/C-ZrC-SiC composites were studied. Results demonstrated the composites prepared from the preform with a density of 0.91 g/cm3 showed a dense microstructure and...
