An automotive vehicle frame reinforcement system has a skeleton member (16) designed to be placed in a cavity defined in a vehicle frame, such as a roof or pillar section. An expandable material (30), such as an epoxy-based reinforcing foam, is disposed on the skeleton member (16). Once the system is attached to the frame, the foam expands and cures during an automobile assembly operation, bonding the reinforcement system to the frame. As a result, the reinforcement system provides enhanced load distribution over the vehicle frame without adding excessive weight.

Un système de renfort de structure de véhicule automobile, comprend un élément ossature (16) conçu pour être placé dans une cavité délimitée dans une structure de véhicule, tel qu'un toit ou un montant avant. Un matériau expansible (30), tel qu'une mousse de renfort à base d'époxy, est placé sur l'ossature (16). Une fois que le système a été fixé à la structure, la mousse se dilate et durcit au cours d'une opération de montage du véhicule, liant le système de renfort à la structure. Ainsi, le système de renfort permet une répartition de charge améliorée sur la structure du véhicule, sans poids supplémentaire excessif.
