Abstract

Une barre en plastique capable de supporter des forces élevées de pression et de traction sert également à transmettre un couple. Des fibres (5) encastréees dans le plastique (1a) sont fixées par liaison de forme dans des rainures (6) transversales à l'axe de la barre et fixées dans des évidements (8, 9, 10) des arêtes (7) qui délimitent les rainures (6) de façon à transmettre le couple. Par sa résistance et sa capacité de transmission de couple, cette barre de compression ou de traction est particulièrement utile comme arbre cardan de véhicules à moteur.
