Carbon/carbon composites with an apparent density higher than 1.80 g/cm 3 were prepared using a multi-step densification process. This consists of a pre-densification step followed by pitch impregnation/pyrolysis (I/P) cycles carried out under modera

International audience; We report on an in-situ monitoring of graphite oxidation using a high temperature environmental scanning electron microscope. A morphological transition is clearly identified around 1040 K between hexagonal pits at low tempera
