Abstract
The use of polyamide modified by hydroxyaromatic compounds employed in the impregnation of reinforcing materials taking the form of a cloth of industrial fabrics for the manufacture of composite materials is described. The described use relates to composite materials and of their manufacturing processes. Also described, is a process for the manufacture of a composite article including at least: a) a stage of impregnation of a reinforcing cloth with a polyamide composition in the molten state, where the polyamide includes hydroxyaromatic units chemically bonded to the polyamide chain; and b) a stage of cooling and subsequently recovering the composite article.
