Starting with a typical dual-service steel tailgate design, a computer (with some empirical help) carried out requisite finite element analyses to study alternative designs maximizing benefits of aluminum, steel, and fiber-reinforced plastic (FRP). Tradeoffs among yield, stiffness, and cost were investigated. Deflections and expense ruled out aluminum configurations, but the initial unit could be redesigned in high strength steel with a 25% weight and possible 10% cost saving. A preferred solution yielded an FRP unit using only two major component parts, saving 35% in weight, and costing about 15% more.
