Abrégé
(EN) A thermoset composite material that my used in the fabrication of structural components including railroad ties comprise a substantially homogeneous blend of an amount of vulcanized rubber particles including a predetermined ratio of different particles sizes, and a thermoset elastomeric binding agent added to the vulcanized rubber particles. The blend may comprise about 30% to about 97% by weight of the vulcanized rubber particles, and the blend is subjected to compression molding at a predetermined temperature and pressure for a resident time period forming the composite material. The ratio of different rubber particle sizes is selected so that the composite material has a desired density or is within a range of desired densities.
(FR) Un matériau composite thermodurci pouvant être employé dans la fabrication de composants structuraux, y compris des traverses de chemin de fer, comprend un mélange essentiellement homogène d'une quantité de particules de caoutchouc vulcanisé incluant un rapport prédéterminé de granulométries différentes, et un agent liant élastomère thermodurci ajouté aux particules de caoutchouc vulcanisé. Le mélange peut comprendre entre environ 30 % et environ 97 % en masse des particules de caoutchouc vulcanisé, et le mélange est soumis à un moulage par compression à une température et une pression prédéterminées pendant une durée de temps de résidence permettant de former le matériau composite. Le rapport des différentes granulométries de caoutchouc est choisi de sorte à ce que la matière composite présente une densité recherchée ou soit comprise dans une gamme de densités recherchées.
