Title
(EN) POLYMER MATRIX REINFORCED STIFFENING ELEMENT AND METHOD OF PRODUCING THE SAME
(FR) ÉLÉMENT RAIDISSEUR RENFORCÉ PAR UNE MATRICE POLYMÈRE ET PROCÉDÉ DE PRODUCTION CORRESPONDANT
Abstract
(EN)
A bend stiffener, and a method of producing the same, comprising an elongated cylinder of a polymer material, having a termination interface (4) on at least one end. An internal reinforcement matrix is provided comprising a first layer of a cylindrically arranged woven material (2). The material of the first layer is unwoven at the termination end, the unwoven fibers engage the termination member (3) and pass back over the first layer. The returning fibers of the second layer may be cut at a plurality of lengths to provide zones (10, 11, 12) of decreasing fiber density from the termination end.
(FR)
La présente invention concerne un raidisseur non flexible et son procédé de production, qui comprend un cylindre allongé formé d'un matériau polymère, possédant une interface de terminaison (4) sur au moins une extrémité. Selon l'invention, une matrice de renforcement interne comporte une première couche d'un matériau tissé (2) disposé de manière cylindrique. Le matériau de la première couche n'est pas tissé à l'extrémité de terminaison, les fibres non tissées se trouvant en contact avec l'élément de terminaison (3) et étant repassées par-dessus la première couche. Les fibres de la deuxième couche qui sont repassées peuvent être coupées à une pluralité de longueurs pour former des zones (10, 11, 12) ayant une densité de fibres décroissante depuis l'extrémité de terminaison.
