Latest Patents

One of Alain Nale's latest patents is a method of protecting products of composite material against oxidizing. This method involves forming a coating on the composite material, which contains a mixture of a non-oxide refractory ceramic in finely-divided form and at least one refractory oxide that provides healing properties by forming a glass. The binder used is a polymer that acts as a precursor to a non-oxide refractory ceramic, which is transformed into a ceramic to create a protective layer. This layer consists of a non-oxide refractory ceramic phase and a healing phase, forming two interpenetrating lattices. A final heat treatment step may be performed at a temperature higher than the softening or melting temperature of the healing phase.

Another significant patent is a process for obtaining an article made of a carbon-containing composite. This process protects the composite material against oxidation by densifying a porous fibrous texture with a matrix. The material is impregnated under vacuum with an alkaline compound in a liquid solution, dried, and heat-treated to create a continuous auto-cicatrizing internal protective coating. An additional external protective layer made of a wear- and oxidation-resistant material may also be applied.
