【Abstract】 The advantage and the ablation mechanism of C/C composites are demonstrated. A physical model of mechanical ablation is established mainly in terms of both the thermoelasticity mechanics and fracture mechanics. Then, the influence of environment and the appearance and disappearance of surface roughness are discussed. The mechanical ablation and thermo chemical ablation of C/C composites are analyzed. All these make some helpful discussion for thermal protection materials.更多还原
