OPTIMAL SUBSTITUTION OF LIGHTWEIGHT MATERIALS IN AUTOMOBILES
This paper presents a relatively simple technique useful for determining the most economically attractive materials mix given the weights and costs of all material-component combinations and an overall weight target. The technique has been applied to a production mid-sized vehicle to obtain optimal material mixes for 26 structural components. The competing materials include mild steel, aluminum, high strength low alloy steel (HSLA), E-glass and five different graphite reinforced plastic hybrids. A computer program was developed to perform the necessary calculations. The results of several cases are presented and analyzed.
