In spite of their environmental appeal, the use of natural fiber composites (biocomposites) for load-bearing applications has been restricted because of their low mechanical properties. However, the performance of biocomposite components can be overcome by using optimized designs. A finite parametric approach to material layout optimization was investigated and implemented to improve the performance of cellular structural components made from biocomposites. Unlike traditional topology optimization, the presented approach leads to optimized material layouts while permitting the use of multiple objectives and constraints. The optimization procedure was validated using benchmark topology problems. Small-scale component testing was conducted to evaluate the structural performance and manufacturing feasibility of the optimized solutions.
