Pyrolytic Densification of Porous Carbon-Carbon Composite Materials

摘要

This paper examines the densification of the pore space of a carbon-carbon composite material through methane pyrolysis at a reduced pressure and the dynamics of the pyrolytic saturation process. The morphology and microstructure of the pyrolytic carbon are compared to those of the main components of the parent carbon-carbon composite material. The composite is characterized by hardness tests before and after the pyrolytic densification of the carbon matrix.
