Title (EN) METHOD OF THERMAL SPRAY COATING FIBER-REINFORCED COMPOSITE MATERIALS
(FR) PROCÉDÉ DE REVÊTEMENT, PAR PULVÉRISATION THERMIQUE, DE MATÉRIAUX COMPOSITES RENFORCÉS PAR DES FIBRES
Abstract:
(EN) A method of coating a fiber-reinforced composite material includes providing a fiber- reinforced composite workpiece, treating a surface of the workpiece to remove at least a portion of a polymer matrix and to expose fibers to a treated surface of the workpiece, and coating the treated surface of the workpiece using a thermal spray coating process. The treatment can include laser ablating or applying a peel ply process. The method yields a coated fiber-reinforced composite workpiece with the coating being bonded directly to the fibers via diffusion of the coating into the fibers, the formation of an intermediate compound at an interface of the coating and the fibers, or both.
(FR) L'invention porte sur un procédé de revêtement d'un matériau composite renforcé par des fibres, le procédé consistant à fournir une pièce en matériau composite renforcé par des fibres, à traiter une surface de la pièce pour éliminer au moins une partie d'une matrice polymère et découvrir des fibres afin d'obtenir une surface traitée de la pièce, et à revêtir la surface traitée de la pièce par un procédé de revêtement par pulvérisation thermique. Le traitement peut comprendre une ablation au laser ou l'application d'un procédé utilisant une couche provisoire. Le procédé permet d'obtenir une pièce en matériau composite renforcé par des fibres revêtue, le revêtement étant directement lié aux fibres par diffusion du revêtement dans les fibres, formation d'un composé intermédiaire au niveau d'une interface du revêtement et des fibres, ou les deux.
