ABSTRACT:
A process for the production of a panel, of the honeycomb support type clad on opposite sides with a skin of carbon/carbon or carbon/ceramic composite. A honeycomb support is produced by pyrolysis of a carbon cloth pre-impregnated with a thermosetting resin. Skins are produced from carbon cloth pre-impregnated with a thermosetting resin. The support and the skins are assembled with a carbon cloth pre-impregnated with a thermosetting resin between them. The assembly is polymerized and then pyrolyzed. Finally, a chemical infiltration in vapor phase is carried out for densification and reinforcement of the bonding of the assembly. Used in the production of structures requiring very high dimensional stability, such as those used in outer space.
