Title
(EN) A NOVEL AMIDE ACID OLIGOMER PROCESS FOR MOLDING POLYIMIDE COMPOSITES
(FR) NOUVEAU PROCÉDÉ D'OBTENTION D'OLIGOMÈRE D'ACIDE AMIDE POUR LE MOULAGE DE COMPOSITES DE POLYIMIDE
Abstract
(EN)
An amide acid oligomer (AAO) solution, methods of making the same, powder, AAO solution prepregs, AAO dry prepreg, imide prepregs, and fiber reinforced polyimide composites with high temperature resistance and excellent mechanical properties are disclosed herein. In some embodiments, a method of making an AAO solution includes dissolving an aromatic diamine and an aromatic tetracarboxylic compound in a solvent to form a mixture, wherein the solvent has a boiling point of less than l50°C; stirring the mixture at a temperature ranging from about 5°C to about 60°C for about 1 hour to about 24 hours to form a reaction solution; adding unsaturated acid anhydride to the reaction solution; and stirring the reaction solution at a temperature ranging from about 5°C to about 60°C for about 1 minute to about 180 minutes to form an amide acid oligomer solution, the amide acid oligomer solution having amide acid oligomer in the solvent.

L'invention concerne une solution d'oligomère d'acide amide (AAO), des procédés de préparation de celle-ci, une poudre, des pré-imprégnés de solution d'AAO, un pré-imprégné sec d'AAO, des pré-imprégnés d'imide et des composites de polyimide renforcés par des fibres ayant une résistance à la température élevée et d'excellentes propriétés mécaniques. Dans certains modes de réalisation, un procédé de préparation d'une solution d'AAO comprend l'étape consistant à dissoudre une diamine aromatique et un composé tétracarboxylique aromatique dans un solvant pour former un mélange, le solvant ayant un point d'ébullition inférieur à 150 °C ; à agiter le mélange à une température allant d'environ 5 °C à environ 60 °C pendant environ 1 heure à environ 24 heures pour former une solution de réaction ; à ajouter de l'anhydride d'acide insaturé à la solution de réaction ; et à agiter la solution de réaction à une température allant d'environ 5 °C à environ 60 °C pendant environ 1 minute à environ 180 minutes pour former une solution d'oligomère d'acide amide, la solution d'oligomère d'acide amide ayant un oligomère d'acide amide dans le solvant.
