Title (EN) A REINFORCEMENT STRAND FOR REINFORCING A POLYMER ARTICLE
(FR) BRIN DE RENFORT POUR RENFORCER UN ARTICLE POLYMÈRE
Abstract:
(EN) A reinforcement strand (400) comprises a core (403) around which steel filaments (404) are twisted all with the same final lay length and direction. The steel filaments are arranged in an intermediate layer comprising N first steel filaments and an outer layer of 2N steel filaments circumferentially arranged around the intermediate layer. In the intermediate layer filaments will contact one another at a closing lay length that is determined by the number of steel filaments N in the intermediate layer, the diameter of the core and the diameter of the first steel filaments. By choosing the final lay length and direction equal to the between two and six times the closing lay length gaps will form between the intermediate layer filaments. The 2N outer layer filaments are further divided into a group of smaller (408) and a group of larger (406) diameter steel filaments.
(FR) L'invention concerne un brin de renfort (400) qui comporte une partie centrale (403) autour de laquelle des filaments d'acier (404) sont tous torsadés avec les mêmes longueur et direction de pose finale. Les filaments d'acier sont disposés dans une couche intermédiaire comprenant N premiers filaments d'acier et une couche externe de 2N filaments d'acier disposés de manière circonférentielle autour de la couche intermédiaire. Dans la couche intermédiaire, les filaments entrent en contact les uns avec les autres au niveau d'une longueur de pose de fermeture qui est déterminée par le nombre de filaments d'acier N dans la couche intermédiaire, le diamètre de la partie centrale et le diamètre des premiers filaments d'acier. En choisissant la longueur et la direction de pose finale de façon à ce que la longueur soit comprise entre deux et six fois la longueur de pose de fermeture, des espaces se forment entre les filaments de couche intermédiaire. Les 2N filaments de couche externe sont en outre divisés en un groupe de filaments d'acier de petit diamètre (408) et un groupe de filaments d'acier de plus grand diamètre (406).
