Oxidation and ablation of 3D carbon-carbon composite at up to 3000 °C Original Research Article

The reactivity of fine-weave pierced 3D carbon-carbon composites in air at temperatures up to 3000 °C was studied. The corrosion morphology and microstructure of oxidized samples were investigated by XPS, SEM, and XRD techniques, and the non-equilibrium nature of the oxidation process was pointed out. A thermochemical ablation model of CC composites controlled by gas phase diffusion and reaction kinetics was developed.
