Abstract

A structural reinforcement system (10) for use with hydroform tubes (18) and other closed forms having a purality of members (12) designed to be secured to a closed form, such as an hydroform tube (18) used in automotive applications.
A bonding material (14), such as an epoxy-based reinforcing foam, is disposed on at least a portion of the outer surface of each of the plurality of members. Once the system is attached to the closed form, the foam expands and cures during an automobile assembly operation, bonding the reinforcement system to the hydroform tube and the members. As a result, the reinforcement system provides enhanced load distribution over the vehicle frame without adding excessive weight and further serves to reduce noise and vibrational characteristics of the automotive vehicle.
