U.S. Marine Corps High Mobility Multi-Wheeled Vehicles (HMMWVs) are equipped with heat-treated aluminum body panels that cannot be welded and must be repaired by riveting sheet metal patches onto them, a process requiring power tools available only at a maintenance facility. This program demonstrated the feasibility of developing a field-applied, corrosion-resistant, permanent repair patch for ground combat support vehicles. A unique, low temperature cure (LTC), hydrophobic composite matrix resin material and a water-based, sol-gel surface treatment were used to attain the corrosion-resistance and mechanical properties required for the Vehicle Repair Patch (VRP). All materials developed for the VRP application process were environmentally compliant, containing no volatile organic components (VOCs) and no chromium-based compounds. The results of our efforts to develop a user-friendly prototype field repair patch kit for military and commercial vehicles will be presented.
