Title (EN) TWO PIECE BONDED VEHICLE COMPONENTS FORMED BY SHEET MOLDING COMPOUND-RESIN TRANSFER MOLDING ASSEMBLIES
(FR) COMPOSANTS DE VÉHICULE COMPOSITES À DEUX ÉLÉMENTS FORMÉS PAR DES ENSEMBLES DE MOULAGE PAR TRANSFERT DE RÉSINE-COMPOSÉS DE MOULAGE EN FEUILLE
Abstract:
(EN) A vehicle component including a first cured outer layer of a molding composition having hollow glass microspheres and a predominant fiber filler of chopped glass fibers; a second cured inner layer of molding composition having a predominant fiber filler chopped carbon fibers in an epoxy matrix; and a bonding agent with elongation properties configured to accommodate the differential coefficients of linear thermal expansion between the first cured outer layer and the second cured inner layer.
(FR) L'invention concerne un composant de véhicule qui comprend une première couche externe durcie d'une composition de moulage contenant des microsphères de verre creuses et une charge prédominante de fibres constituées de fibres de verre coupées; une seconde couche interne durcie de composition de moulage ayant une charge prédominante de fibres constituées de fibres de verre coupées dans une matrice époxy; et un agent de liaison ayant des propriétés d'allongement configuré pour s'adapter aux coefficients différentiels d'expansion thermique linéaire entre la première couche externe durcie et la seconde couche interne durcie.
