Title
(EN) COMPOSITE ARTICLE OF VARYING THICKNESS AND ITS PRODUCTION
(FR) ARTICLE COMPOSITE D'EPAISSEUR VARIABLE ET SA PRODUCTION
Abstract
(EN) A composite article (4) of fibre-reinforced matrix material incorporates crushable elements (7) e.g. tubing of braided filaments or yarns, which are at least partly crushed (at 13-16) to give the article reduced thickness in the area (9, 10) of the crushed elements. A method of producing such an article involves subjecting the fibre-reinforced matrix material to externally applied forces to cause different degrees of crushing in the element(s).
(FR) Article composite (4) en matière matricielle renforcée par des fibres, comprenant des éléments (7) déformables par écrasement, par exemple un manchon de filaments ou de fils tressés qui sont au moins partiellement écrasés (en 13-16) pour donner à l'article une épaisseur réduite dans la région (9, 10) des éléments écrasés. Un procédé permettant de produire un tel article consiste à soumettre la matière matricielle renforcée par des fibres à des forces appliquées de l'extérieur, afin de provoquer différents degrés d'écrasement dans le(s) élément(s).
