METHOD FOR THE OXIDATION PROTECTION OF ARTICLES MADE OF A CARBON-CONTAINING COMPOSITE MATERIAL |
摘要 |
Prior to applying an impregnation composition constituted by a solution of at least one phosphate, a part made of composite material is treated in depth by means of an aqueous solution that penetrates into the open internal pores of the composite material, and is then dried. The aqueous solution contains an additive which, after drying, imparts to the composite material, increased wettability by the impregnation composition. The additive contained in the aqueous solution is preferably constituted by at least one wetting agent that is soluble in water and non-ionic, such as an oxyethylenated fatty acid, an oxyethylenated fatty alcohol, an oxyethylenated alkyl-phenol or an ester of a high polyol.
