The actual trend in composites industry is to use modified polymers as matrix to form materials and structures with better properties. In this regard this study is oriented toward finding ways to improve polymer properties based on natural tendency of starch to create its own structure when is dispersed into a liquid phase. A bi-component epoxy system was used to form particulate composites with various starch concentrations. Physical and mechanical properties of formed materials were investigated using appropriate methods to identify the maximum amount of starch to be added without changing the basic properties of epoxy matrix. The results are encouraging further studies regarding the possibility to use starch as primary dispersion in pre-polymer mixture in order to ensure better dispersions for powders which generally tend to aggregate.
