摘要

The carbon felt reinforced HfC-C/C and C/C composite integrated throats were prepared by thermal gradient chemical vapour infiltration process, and their ablation resistance was determined by using an equipment of solid rocket motor under the pressure of 7MPa. The effects of carbon hafnium on ablative properties of the integrated throat were investigated by scanning electron microscope (SEM) and energy dispersive spectroscope (EDS). The results show that the ablation behavior of the HfC-C/C composite integrated throat has characteristic of a steady ablation stage with constant linear ablation rate. Compared with those measured for the C/C composite integrated throat, the linear and mass ablation rates of the HfC-C/C composite integrated throat are decreased by 34% and 13%, respectively.
