Abstract
Resins and thermoset composites comprising them, these materials being able to be hot-fashioned. These compositions resulting from placing at least one thermosetting resin precursor, this thermosetting resin precursor comprising hydroxyl functions and/or epoxy groups, and optionally ester functions, in contact with at least one hardener chosen from carboxylic acids, in the presence of at least one transesterification catalyst whose total molar amount is between 5% and 25% of the total molar amount of hydroxyl and epoxy contained in the thermosetting resin precursor. Process for manufacturing these materials, process for transforming and process for recycling these materials. New solid forms of resins and of thermoset composites that may be used in the implementation of these processes.
