In a method for making a hybrid leaf spring, at least one layer of composite material (18, 20) is molded onto a metal primary leaf (16) using a mold (14) having an interior cavity (12) defined by at least one cavity wall. Heaters (36) for independently controlling the temperature of the metal primary leaf are also provided with the primary leaf and the layer of composite material being positioned in the mold adjacent to one another. A layer of adhesive (26, 28) is positioned between and in engagement with both the layer of composite material and the metal primary leaf. A controller (42) having heating data stored therein is employed to actuate the heater in response to commands generated therefrom causing thermal energy to conduct into the adhesive material and the layer of composite. This method minimizes adhesive cure times which is a common problem with prior art methods in which the metal primary leaf acts as a heat sink, drawing heat away from the adhesive layer.

L'invention concerne un procédé de fabrication d'un ressort à lames hybride dans lequel au moins une couche d'un matériau composite (18, 20) est moulée sur une première lame métallique (16) au moyen d'un moule (14) possédant une cavité interne (12) définie par au moins une paroi de cavité. Des appareils de chauffage (36) sont destinés à réguler de manière indépendante la température de la première lame, cette première lame et la couche de matériau composite étant adjacentes l'une à l'autre dans le moule. Une couche adhésive (26, 28) est placée en contact entre la couche composite et la première lame métallique. On utilise un contrôleur (42) dans lequel sont stockées les données de chauffage afin d'actionner l'appareil de chauffage en réponse à des commandes générées par ce dernier, ce qui entraîne la conduction d'énergie thermique dans le matériau adhésif et la couche composite.
