Abstract
The invention relates to a composite material element (), the composite material comprising a microfissured matrix () in the form of a three-dimensional interconnected network () of microfissures exposed on the surface of the ceramic matrix, an additive material () consisting of a flux or glass being dispersed in the matrix, the additive material () being a material which, when the composite material is brought to a predetermined temperature, softens and migrates by capillarity in the network () of microfissures () to said surface of the element. The quantity of additive material dispersed initially in the matrix is in a sufficient proportion compared to the matrix intended to coat a surface () of the composite material element left exposed so as to create a gas-tight barrier.
