An automotive vehicle frame reinforcement system has a skeleton member designed to be secured to a vehicle frame, such as a roof or pillar section. An expandable material, such as an epoxy-based reinforcing foam, is disposed on the skeleton member. 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.
