A reinforcement device may include at least one elongated reinforcement body having a longitudinal axis and at least one foamable member that produces a foamed product when heated. The foamable member is preferably disposed along the longitudinal axis of the reinforcement body so that the foamed product will extend along the longitudinal axis of the reinforcement body. Preferably, the foamed product bonds the reinforcement body to a hollow structural member in order to reinforce the hollow structural member.
