(EN) COMPOSITE STRUCTURES HAVING IMPROVED HEAT AGING AND INTERLAYER BOND STRENGTH
(FR) STRUCTURES COMPOSITES À MEILLEUR VIEILLISSEMENT THERMIQUE ET À PLUS FORTE RÉSISTANCE D'ADHÉSION ENTRE LES COUCHES
Abstract
(EN)
The present invention relates to the field of composite structures having improved heat aging, processes for making them, and end use articles. The composite structures of the present invention comprise a polyamide matrix resin composition comprising from 0. 1 to at or about 3 weight percent of a matrix heat stabilizer based on the weight of the polyamide matrix resin composition; a fibrous material and a polyamide surface resin composition comprising 0. 1 to 3 weight percent of a copper based heat stabilizer based on the weight of the polyamide surface resin composition; wherein: the matrix heat stabilizer is different than the copper based heat stabilizer; and wherein the fibrous material is impregnated with the polyamide matrix resin composition.

La présente invention concerne le domaine des structures composites présentant un meilleur vieillissement thermique, leurs procédés de fabrication et des articles d'utilisation finale. Les structures composites de l'invention comprennent une composition de résine matricielle de polyamide comportant de 0,1 à environ 3 pour cent en poids d'un stabilisateur thermique matriciel, sur la base du poids de la composition de résine matricielle de polyamide; une matière fibreuse et une composition de résine de surface de polyamide comprenant de 0,1 à 3 pour cent en poids d'un stabilisateur thermique à base de cuivre, sur la base du poids de la composition de résine de surface de polyamide; ledit stabilisateur thermique matriciel étant différent du stabilisateur thermique à base de cuivre; et ladite matière fibreuse étant imprégnée de la composition de résine matricielle de polyamide.
