Abstract
A vehicle body includes a hollow structural member having an inner surface. The hollow structural member includes a first metal or metal alloy. A structural reinforcement member is positioned in the hollow structural member and includes a stiffener including a second metal or metal alloy different from the first metal or metal alloy. A gap is provided between the stiffener and the inner surface of the structural member. An adhesive is secured to the stiffener. The adhesive is substantially dry to the touch prior to activation and is activatable to expand toward the inner surface to fill at least a portion of the gap. A frame is secured to the stiffener and is positioned between the stiffener and the inner surface of the structural member to maintain the gap prior to expansion of the adhesive. The frame is adapted to insulate the stiffener from the hollow structural member.
