Development of Substrate Formulation via Simplex Mixture Design

The intent of this paper is to demonstrate the benefits of using experimental design techniques in product formulations. In this example, an optimized product was developed using minimal experimental trials by the use of a simplex mixture design. The resultant product was tailored within mechanical property, weight, and cost constraints. The new formulation was developed, prototyped, and tested quickly in order to be available to substitute for a heavier, more expensive steel and aluminum part.
