Abstract

Il est décrit une méthode de fabrication dun échantillon tubulaire ayant un effet de pli prédéterminé consistant à fournir un outil dempilage ayant un élément de formation de cavité ayant une cavité qui ressemble à une forme souhaitée dudit au moins un pli; à orienter un matériau composite autour du mandrin à un angle denroulement pour former une boucle fermée; à positionner un outil de pli sur la boucle fermée; et/ou à générer au moins un pli avec une caractéristique prédéterminée dans une partie de la boucle fermée pour former un échantillon tubulaire. La caractéristique prédéterminée est au moins lun des éléments suivants : un emplacement de pli, un pli vers lextérieur, un pli vers lintérieur, une largeur de pli, une hauteur de pli et une longueur de pli. Selon un autre aspect, il est décrit un procédé de test de charge décalée dun échantillon composite tubulaire. Selon un troisième aspect, il est décrit une méthode pour déterminer les défauts admissibles pour un composant composite.
